DexCool in GM Engines

Lorraine of Canonsburg PA (10/07/08)
dex coolant problem intake gasket replaced, and now a blown motor.

out of a car

Joeleen of Independence MO (10/04/08)
From reading the Dex-Cool Lawsuit against GM my car should qualify, but because it is a 1999 Cavalier and has 148000+ miles I guess it doesn't. Basically, I could never keep coolant in the car. It would not leak anywhere that I could see, but would run hot alot and low on coolant.

Just last week the car went less than 3 miles and went all the way to the red zone. It was shut down to cool off and then would not start again. So now we have it tore apart hoping all the needs to be fixed is the headgasket and at the worst case the head.

Allison of Jonesboro GA (10/01/08)
my car is leaking antifreeze from the head gaskets, causing the car to over heat and not hold any antifreeze, as soon as you refill the resivor it immediately pours onto the ground causeing you to stop because the low coolant light comes on, you must stop to replace the coolant after it cools, this happens as little as 1-2 miles after placing and filling the resevior with fresh coolant.

damaged the heads and with the car with over 150,000 miles it's explained that the heads can not be removed and rebuilt or new ones added for it will shut the entire motor down because the motor will not be strong enough to handle new heads, so I'm advised to purchase a new motor which is 3500.00 from the manufacture uninstalled.

Robert of Dunkirk IN (09/27/08)
having problems with 2003 montana you can smell antifreeze when you turn heater or air through the vents. it trys to over heat but fans keeps it from happeing. it goes all the to the red. couldnt get cap off when finally did there was rusty color sludge real thick gooey stuff in the raditor.

have appt. to get it flushed it looked realy nasty. they say to only use this product in the manual but it seems it hurts it not help it.

Steve of Sacramento CA (09/18/08)
I have owned a 97 Blazer since 98. It has a 4.3 V-6 and came with Dex-Cool. My first DC (Dex-Cool) problem waswith the coolant resevoir, the hose from the radiator to it was plugged with sludge.I drained and re-filled the resevoir and radiator with DC. A few months later, my mechanic advised me to keep an eye on the radiator as it seemed to be filling up with sludge and had a small leak. Next the water pump failed and my mechanic told me it was plugged with DC sludge. He replaced that and advised the radiator will not last much longer, he flushed the system again and re-filled with DC. Six months later I had an intake manifold gasket leak and the coolant hoses were collapsing. My mechanic replaced the intake gasket, the radiator, flushed the system again and replaced the coolant hoses, the heater hoses, the watr intake and the thermostat and we switched to green coolant. No further problems in 12 months. But now I see I am aced out of the Ca class action suit not by mileage, I have 120k on my Blazer, but by time!!! The suit allows for claims only if repairs are done within 7 years of the vehicles age, mine is a 97. What a crock. Now I know I will NEVER buy another GM vehicle.

Marion of Cedarville NJ (09/16/08)
engine collant leakage all gaskets in engine had to be replaced

$800.00 in repairs

Linda of Knoxville TN (09/15/08)
I have been having trouble with my 1997 Monte Carlo over heating. I had the radiator flushed & refilled about a year ago because I thought It was really dirty and full of rust, then I found out the Dex-cool causes this. That was after I had to have a new water pump put on the car. I also had to replace the radiator cap because so much gunk had built in it that it wouldn't work. I have always made sure my radiator was filled properly. Also, my air conditioner will not cool properly and I have to keep adding coolant to it. If a class action law suit is filed against GM I would very much like to be contacted concerning this matter.

Barry of Dayton OH (09/14/08)
I bought our 2002 silouhette new and we had a problem with the intake leaking but it was under warranty so we had it fixed.Well every since then it seems to run alittle hot and we smell coolant but can't see it leaking anywhere.if someone can help please let me know.thanx

Michael of Canisteo NY (09/14/08)
Coolent leak needed lot of engine and cooling system repairs. The coolant ate the gaskets in the engine and caused slug to enter the engine and damage the cooling system. this caused many problems many hours larbor no car to drive for a long time and at great csot to me.

The repairs were extremly expensive and I was with out my car for a very long time and residual problems as well.

Mike of Nixa MO (09/08/08)
I have a 1999 chevy S10. I was travelling down I-44 when the lower heater hose blew and I had to have the vehicle towed to my mechanic. I thought this would be a simple, inexpensive fix. However, to my suprise, the mechanic told me he performed a pressure test of the system and dexcool antifreeze began to shoot out of the head gasket, exhaust manifold gasket, and exhaust. He then removed my radiator cap and it had so much sludge on it that the spring mechanism would not work. The radiator was full of sludge that looked like Alabama red clay. I then noticed that around the thermostat housing it also appeared to be leaking. Upon further inspection the DEXCOOL coolant had eaten the end of the metal line and that's why it was leaking. My thermostat was stuck open because it had so much sludge in it and would not work.

I have since had to spend $1500.00 to repair my vehicle. I had to replace the radiator, thermostat, thermostat housing, water pump, head gasket, exhaust manifold gasket, and had to have my head sent off to a machine shop to be checked and machined and cross decked. Then after all this is was still leaking antifreeze and now I have had to replace the freeze plugs on the driver's side because the pH level was so high it was eating them from the inside out. I called the 1-866 number listed on the website for the lawsuit and was told that because my engine is a 4 cylinder, I am not included in the litigation. I then contacted GM customer service via there 800 number and was told the same thing. When I asked to speak to a supervisor they said they couldn't give me that information. I think this is a great injustice to the American public because GM knows that DEXCOOL is causing these problems and they are not standing behind their products. I also feel that the 2.2L 4 cylinder engines should be included in this lawsuit because my mechanic is an ASE certified mechanic and former GM mechanic and will testify that DEXCOOL coolant was and is the culprit in my situation and several other vehicles he has had to repair as a result of DEXCOOL. Any help with this matter would be greatly appreciated

Frank of Angwin CA (09/02/08)
I bought a Olds 99 Alero 3.4 used back in 2007. It had approx 120,000 miles on the engine. I went on a trip to Tenn from Missouri (the state I bought the car from). I had a major leak and had to replace the hoses. I noticed the coolant was thick and sludge look to it. I added new coolant and hoses and I still have problems with over heating and just recently have had the gasket replaced because it was leaking coolant. The eng temp always runs hotter than normal. I was told the coolant was causing my problems with the gasket problems and the overheating. Help Thanks Greg

Saul of Los Angeles CA (08/26/08)
My car had overheated when i used this product of dexcool and which caused my head gasket to be filled with water and liquids inside the engine, and caused my radiator to leak

engine trouble and paying over $900 in repairs of replacing a radiatior and repairing a head gasket

Jon of Chelmsford MA (08/25/08)
Dexcool used by General motors to cool my Buick Century engine

Sludge has built up in my coolant.Engine oil leaks into my engine coolant.

Marsha of Dublin GA (08/25/08)
I am currently purchasing a 2002 malibu. I have been having problems with the tempeture for quite some time now. The irst incident happend early last year I would smell antifreeze in my car through the vents. I always keep my eye on my temp. guage it will always read norm. Over time my temp. hand would go up but not past normal. Last Nov. my car ran hot raditor fluid was just spewing from where I do not know. So I called my boyfriend he put water in my car and we took it to a mechanic who could not find a leak and replaced it with DexCool. Few months after that I found myself having to have to top my coolant off maybe every two weeks. I took my car back to my mechanic and he told me I need work on my intake manifold gasket which would be $1200.

My mechanic charged me $1200.00 for the services and labor. My temp. hand still reads above normal. I cant afford all this Im paying for this car I am still making payments. I am a single mother of two.

David of Bthlehem PA (08/24/08)
Just found out I need all new gaskets for my 99 olds Alero because dexcool is dissolving them. Same over heating as the thousands of other people are having. How do I find out about the class action suit?

$1656 and two days without my car which I CAN NOT DO. That's over a months pay for me.

Druann of Equality AL (08/20/08)
We have spent $2500 on our Buick Century that had Dexcool in it. We feel it is from the Dexcool. That is what the mechanic indicated.

Sherry of Pasadena MD (08/20/08)
took my car to get the oil change and the man told me to check out the pending law suit with GM about Dexcool coolant causing brown sludge build in the radiator and needing to be flushed and clean out before something happens.

Renee of Elizabeth NJ (08/18/08)
I have a 2001 Chevy Monte Carlo. Using Dex Cool coolant has caused me to get my Manifold Intake, Headgasket, and Radiator replaced!...It cost me over $1500 to get all parts replaced!

First my radiator started leaking brown fluid..then my car couldn't accelerate like it normally did...then my enginge started making a grinding noise...everything happened within a week span!...

Brian of Douglasville GA (08/16/08)
I paid 16000.00 for a 2003 chev 4x4 truck. The price would indicate that I had purchased a vehicle in good condition. Less than 1 year I had to replace the radiator and head gasket and hose. I had to disconnect the hose to my heater because of leaking from the core. I have already spent 2500.00 and can't afford to fix the heater. I have never nor have any of my friends owned a vehicle that had these problems even after 10 - 14 years.

Something unusual had to cause this problem. My problems are exactly like those I have been reading about, but my vehicle was out of the age range for the dex cool. Same problem, same sludge, same brand of vehicle.

Tman of T Dot OTHER (08/14/08)
DEXCOOL is the best you guys are haters and losers

Akemi of Rialto CA (08/14/08)
I am a single mother with 2 children and I totally depend on my car to get me to work. My car started making noises and running hot. I took it to a mechanic and he told me that there was a problem with these cars running hot due to the anti=freeze used in the car. I own a 2003 Grand Prix and this is a hardship of me having to put so much money into a car that I solely depend on and still have to pay the car note. I am frustrated....

I took it to the mechanic and he removed and replace the intake manifold due to a busted pipe and corrosion that makes my car overheat. I am just happy it did not crack the heads. I was charged $553.46. The mechanic told me to look up the problems that I had and put in a claim for it.

Griselda of El Paso TX (08/12/08)
used dex cool as owners manual stated...i drive a 2005 cadillac cts 3.6 liter..after so 1000 miles my car started to leake some type of fluid..brown muddy type fluid, some kind of sludgy liquid ( really bad)..i do understand there has been some issues with dex cool...no having problems with leakege

full internal cooling system damage...

Tammy of Ashland PA (08/11/08)
I have a 2004 Chevy Impala that had to have the head gaskets replaced at67,000 miles which cost me 1372.55 to have fixed. Dexcool is supposed to be so wonderful, but yet I am taking my car back to the dealer today to have it fixed again. My car keeps overheating and I have no heat. The car now has 75,000 miles on it and I should not be having these problems.

Colleen of Hornell NY (08/10/08)
We had a very difficult time with our Delta 88 when using Dex-Cool. The temperature gauge continued to read hot and we ended up having to replace the gasket, and upper intake manifold.

As stated above, we ended up replacing the gasket and upper intake manifold and finally got rid of the car because we were concerned for our safety.

Jill of St. Clair Shores MI (08/07/08)
I have a 2003 Chevy Venture van and started to have problems with it overheating this past winter. Also when temperatures became very cold the engine knocked terribly until my vehicle warmed up good. I had this checked out at serveral shops to see if I would get the same diagnosis. I did get the same diagnosis from each place - that the coolant Dexcool that is used for the engine in this van has caused the gaskets to wear which is causing the coolant and oil to mix, and also slowly leak, causing me to get oil changes more often and have the fluids topped off more often than the recommended 3,000 mile change. I have been given an estimate to fix this problem ranging from $700.00 and up depending on how bad the damage is from this coolant. I am astounded at the amount of complaints on the WEB for this problem and that GM will not recall this and fix the problem. In my opinion with the way the American car industry is suffering right now, this is part of the reason why.

Ruben of Phoenix AZ (08/06/08)
I bought a 2002 Pontiac Grand Am with 80,000 miles on it, and it seemed like Dex Cool coolant had been used since bought. I started having overheating problems due to a bad thermostat, and then water pump failure, and according to the mechanic it was a clogged radiator. After replacing those parts the problem was still there, upon returning to the mechanic he rechecked it and found a problem with the intake gaskets. He said the gaskets were worn out and crystallized, It was also sucking in air through the gasket, causing the car to overheat and lose power. It would also leak all the water and coolant through the reservoir tank making the overheating problem worse to the point of not being able to drive the car anymore. I also found brownish sludge coming out from the engine, it looked like mud. I still don't know how the head gaskets are at this present time but the way it looks I'm pretty sure I'll be having problems in the future. However, I will keep records of all the expenses that I could face.

Heidi of Grandville MI (07/31/08)
The product caused me to have an intake gasket leak and I hear there is a suit against the company that I want to add my name to. I have a 2001 pontiac aztec

I had to pay out alot of money to fix it. and take time off from work.

Carroll of Satillite Beach FL (07/30/08)
My wife and I have a 99 pontiac Bonneville 3.8l and a 2000 GMC Sanoma 4.3 vortec. The bonniville intake started leaking at about 50,000 mile in witch I had to replace the plastic intake. I put on an after market part on and did it myself, cost about 200 dollars, this was about 3 years ago. About one year ago my 4.3 vortec intake started leaking I have only added alumaseal to the system for now but it needs the dexcool flushed out and I am anticipating the leak to come back.

Cost of replacing both the intake on the Bonniville and cost of the repair pending of the GMC Sonoma

Christopher of Fairfield CA (07/23/08)
I am currently going through the ringer due to the cooling system in my 2003 Chevrolet Impala. I have been having problems with this vehicle for over a year now as I purchased the vehicle in 2003 used with approximately 15,000 miles on it. I took it in to a Chevrolet dealer to find that a few seals and gaskets, the water pump and the thermostat need to be replaced for a fee that exceeds $1,000. Although I have my situation meets all the requirements necessary to be eligible for the class action lawsuit, I have found that I am ineligible due to the fact that I did not have this work, that I now need, done by May 30, 2008 as it is now July 23, 2008.

I have been running around like a mad man because I do not know what to do. Due to these unfortunate events, I was pressed to purchase an extended warranty for $1,500 which only covers internal parts. Now I am to pay over $1,000 for my vehicle to be repaired and it has been sitting at the dealership for a week now. I need help...

Andrea of Warner Robins GA (07/23/08)
WE bought a new Oldsmobile Silhouette van in March 2002. It has around 106,000 miles on it now. We have had 3 separate repairs (air conditioner, radiator, and internal gaskets)made to the cooling system in the last 3 months. The total for all 3 repairs is going to be around $1,700. After having the third repair done we began to research this problem online and found out about the different class action lawsuits against GM Dex-Cool. We feel we should be covered for most of the repairs since this is due to defective parts that we should have been informed about.

Multiple days without vehicle, rental car, and expensive out of pocket cost.

Janet of Quincy MA (07/20/08)
Bought a used 2003 malibu that was in the show room as a superior cream of the crop vehicle. After about 6 months the car started to act up so we took it in and after a few hours was told everything was fine. A few months later we were back in the dealers repair center and were told it needed a new engine as the coolant had eaten the head gaskets. We had purchased an underwriters policy for the vehicle so the rebuilt engine only cost us $500.00 when in fact I feel it should have cost us nothing. We were never told that there was a problem with the coolant type or anything at all. If the company knew of the potential problem then why would they put thousands of lives at stake. My only regret is that We went back to the same Co. several times and purchased vehicles from GM. I dont think I will be doing that in the future. Foriegn is now the way to go for sure.

Susan of Hornell NY (07/15/08)
I have experienced major car repairs due to coolant leaking. It has effected gaskets, belts, oil, radiator, water pump and hoses.

It has cost me thousands of dollars and created feared for my safety. I had the car towed because I was too fearful of driving it.

Lisa of Armagh PA (07/15/08)
Replace Several coolant parts due to overwelming sludge, also overheating, 2 water pumps, 4 termastes, 1 raditor, any many gassests.

Monica of Westland MI (07/13/08)
dexcool problems Subject: later year models? July 13, 2008 So what is being done for those of us who have a newer vehicle (2005 Pontiac Grand Am) that is exhibiting the same problem - sludge AND leaking at lower intake manifold gasket? Are we just stuck with having to pay to have the repairs done. I know GM has stated they fixed the problem, but I sure have the same thing going on with my 2005 car.

Carol of Danville OH (07/11/08)
I purchased a 2000 Chevrolet Malibu in May of 2001. At the time of purchase, the car had less than 30,000 miles on it. Within the year, the car developed terrible over heating issues. I took it in numerous times only to be told that the anti freeze DEXCOOL was leaking out and had to be replaced....and that you could only use DEXCOOL in my car. After another frustrating year of over heating, adding DEXCOOL etc I took the car in to my mechanic who informed me that I had to replace the intake manifold gasket for a cost of $800.00. I had the work done, but after seeing the numerous complaints about the DEXCOOL, I have to wonder why GM never sent anything out, was never required to notify consumers that a product that was the new answer to anti freeze was ruining engines. In a country where we spend more time and money on ridiculous matters,why when discovered, would we not require a major automaker to disclose information that is critical to not only automotive safety, but also the financial safety of consumers who buy their products. Is something being done to advise consumers of this problem...or reimbursing those that had to have extensive work done? I am all about personal accountability,and I am for being an adult and sucking it up, but I do not believe that GM should be allowed to get away with not even notifying consumers that there was a problem, or giving us instructions, advise or counsel on how to prevent or fix the problem before it became too costly.

Jill of Canisteo NY (07/09/08)
I had bought A 2000 Pontiac Grand Prix GT with 37,0000 miles in 2004. It had taken me 14 years to get the car I had always wanted. You can imagine my excitement when I drove off the car lot. That is where it ended! I had to take that car back almost every 2 Weeks to have something fixed in it.I had to have so many things fixed in it that I can't remember them all! I did have to have the transmission replaced at 46,000 miles because the bearing inside had fallen apart. That job had cost me around $1800! I continued to have more and more problems. I had to have 4 ignition coils replaced. I started to have ( what i found out later) was a major problem . My car started to act funny. The check engine light started to flash on & off, my temperature gauge light came on, and I had hardly any power. My car wouldn't drive over 20 miles per hour. I had to have it towed. I couldn't take it to the gm certified dealer that I bought the car from because they were no longer in business. I took it to a private garage to have it serviced once AGAIN! They took a look at my car and told me the bad news. I needed to have the SAME ignition coil that I had just replaced ,replaced again, Intake Gasket,Upper Intake Manifold,Radiator Hose(x2), Valve cover Gasket, 2 Oxygen sensors,Coolant Elbow, Water Pump, Serpentine Belt, Thermostat,And Antifreeze.This job cost me $1351.17!!! And thats not all. After I had this job done, 2 WEEKS LATER, I was driving on my way home from work and my car started to act up once again, but this time was the worst. IT STARTED ON FIRE!!!!!!!! And let me just say that when you are a mother and your children ride in that car that is now on FIRE it is one of the scariest things that could happen. I again. I no longer have that car but I can say that I'll be paying on the repairs for a long time!!

Amy of Ypsilanti MI (07/08/08)
Same issues with the gasket on the intake manifold and was also advised to use Dex Cool. We understand there is a class action lawsuit regarding the Dex Cool. However, we are interested in finding out how to get involved.

Matthew of Omaha NE (07/07/08)
I have a 2003 Chevy Impala LS and it only has 50,897 miles on it and I have to spend over $800.00 to get the coolant leak fixed on the intake manifold. I know that it is from the DEX COOL. This stuff is definitly not the 100000 mile antifreeze. This antifreeze is supposed to be orange and it is a rusty color.

I am going to have to pay over $1300.00 dollars to have the gaskets replaced on the intake manifold, as well as one of the head gaskets. Not only that but I am going to have to have my radiator flushed. This Dex Cool coolant is the worst coolant ever created and it is costing the end consumers thousands of dollars. I will never purchase another GM product again. However I do not want to pay to have this fixed as it is not my fault that the DEX Cool is crap!

Natasha of Cincinnati OH (07/07/08)
I had been having an antifreeze leak. Took car into Courtesy Chevrolet on 7-7-08. There,the mechanics made me aware that I had an intake manifold leak that may have cause anti-freeze to leak into engine. I was told that GM was aware of this problem and that they were responsible for reimburstment of any repairs made arriving from Dexcool leak.

Eliot of Van Nuys CA (07/07/08)
I took my 1998 Camaro 3.8 V-6 to a mechanic to determine why my coolant is leaking. It is now a $2200 expense to repair faulty intake manifold gasket and other leaks I beleive are caused by the Dexcool that GM uses. I had it flushed at 50000 miles by the dealer and also at 54000 by the replacement of the water pump. The class action lawsuit looks like I am excluded because the repair is after may 2008, and the age of the car. I only have 94000 miles and have babied this car since I got it. How can I get my money from GM?

Angela of Park Hills MO (07/07/08)
I have one of those cars involved in the class action suit with Dexcool over the coolant damaging the gaskets. I called the number in the lawsuit paperwork to find out how to get in on the suit only to learn that they are limiting the time in which the failure and repairs happened to 7 years. I bought my car a 2000 Chey Malibu used in 2004 or 2005, would have to search through files to find the exact year, and only this year began experiencing the problems associated with the dexcool ruining the gaskets and I also just learned about the problem of the dexcool ruining the gaskets. I don't believe it fair that they are one putting a time limit, as some cars are not driven hard or extensively enough for the problem to manifest itself or that the problem may have begun but was misinterpreted as something else; two I believe that a recall needs to be done now so that those like my self can get this issue resolved. The problem only gets worse as time passes and not everyone can afford to pay $1000's of dollars to have the cars repaired.

Nader of Chicago Ridge IL (07/07/08)
I recently purchased a 1999 monte carlo. I take to get an oil change and a radiator flush. After the man flushs the coolant, he replaces it with dex-coolant. After about 5 minutes i relize that all the coolant has disappeared. I asked him why it did that and he replied it's normal, so he refils it with the same antifreeze. When i got home i see the low coolant sensor pop up. I open the hood and see that the coolant is very low. So i just go ahead and filled it up with the same coolant. One day I get home and turn off my car, then i see it start to smoke. I then hear a sizzling noise in my engine. My friend told me it was the antifreeze mixing with the oil. Now i don't drive my car anywhere because i don't have the money to fix the problem. I then look online to see if anyone had the same problem as me, and suprisingly it seems as dex-coolant is causing problems for everyone. I regret buy the car now.

L of Denver CO (07/02/08)
I just paid over $1000 to have my car fixed. The mechanic took the cover off the engine and showed me how all this coolant was leaking all over the inside of my engine,and causing all sorts of problems for my car. He was the one that told me to look into this situation that GM had some class actions suites against it for this very reason.

Over $1000 in damages due to this situation.

Elvalon of Eads TN (07/01/08)
I am crying!!! I purchased a $40,000.00 so called #1 in the nation, vehicle brand new in 2004. Why did I do that? I have had nothing but problems, problems, problems 6months into having it and ongoing! The latest, I just found out today 6/30/08 why my 2004Yukon has been making a really awful noise after it sits for awhile. Leakage from the DexCool is running into my engine causing the heads and no telling what else all sorts of damage! It is not right that I have to pay for something they officially created! It will be known by the president or somebody what GMC is doing...Number 1, selling poor quality cars and Number 2, at high quality prices! I make my money honestly and would feel better I guess, if I had not been robbed Blue Collar style. They are robbers in diguise

Marion of Wirtz VA (06/30/08)
I need to know more about the Dex Cool Problem. We bought a 2000 Olds Alero in Nov of 2007 and Just this month it started leaking, we have been using Dex Cool.

We had to take the 200 Olds Alero to an auto repair shop and have them fix it. The o rings had let loose and the water jacket (Ibelieve it's called) was cracked in several places.

John of Ashland PA (06/30/08)
We have used Dex-cool in our 2001 Olds Intrigue since new ( stated in owners book) We have had nothing but problems since about 2004 with engine problems we have taken it to certified GM dealers who said the head gaskets on this engine were bad, after that was fixed (or so we thought) it happened again, then we went to a local mechanic that said it is a recurring problem. We still got it fixed again!!

William of Lebanon TN (06/30/08)
The 2000 Cheverolet Impala that i purchased because of the coolant system and use of dex-cool over heats and has caused damaged to the motor i am unable to drive or use my only source of transportation

Wanda of Knoxville TN (06/29/08)
The water pump blew a gasket in 2006 on My 2000 Chevy Malibu and recently needed a 665 dollar replacement of the Intake Manifold Gasket....I am now hearing I should be in with a Class action suit for the Dex-Cool anti-freeze causing these problems.

Dinotra of Plantation FL (06/26/08)
Heard that there is a class action law suit about the company and them only making the vehicles to use the coolant call 'DexCool. This coolant is destroying engines and cars and heating system, leaving customers out of a car and cash because they are not covering the damage. There is currently a class action suit going on and now I am having the same issue. I have a 2006 grand prix and the car guide states that the Dex Cool is the only coolant you can use and the coolant should last 150,000 miles. I am @ 50,000 miles and my car is leaking coolant all over the roads and grass and over heating. This is a problem in over 1,000 GMC car owners and this is sad because gas is high enough, along with insurance and car notes, I can not afford to pay the dealer to fix this problem because this Dex Cool is faulty coolant, caused muddy, rust color damaged to the engine and ultimately will damage the engine and its parts causing over $5,000 in damage. I have to pay to have the car looked at. This muddy rusty slop is laa over my engine parts and under the hood. Its bad enough I cant afford gas, then its insurance and then a car note now this.

I am a single mother of 3 kids. We depend on this car and i never had an accident or any damage to the car resulting for a accident or engine damage. This is going to be an expensive mess. I call GM today and asked where there any recalls and asked if they new anything about a coolant spill and the rep lied and said nope and anything dealing with a spill will be my out of pocket expenses. I though something was fishy and I looked on line only to find over 2,000 complaints about GMC forcing this garbage in our Coolant systems. They give you no other choice. It comes with the orange rusty goop and you have to keep using it but if the car gets damaged from it they want to be held not liable. I am stressed out because I do not have another car or any other forms of transportation. This stuff is all on my grass and drive way and it is bright and it stains. The apartment complex advised me I need to do something bout my car ASAP because it is causing concerns for the residents. This is a shame if it cause this many lawsuits before how can the issue still not be happening? I have a Grand Prix that was running well and now it is running hot, temper gauge is toogling and the mess is all under the hood and engine. Then it states if you spill any on the engine it can cause major engine damage. i don't know this sounds like a set up. I mean i neevr seen anything like this rusty goopy mess. You can not use anything else. If you mix it they will say this is why thecar is causing damage so the light green cheap coolant is out. you have to buy this $13 dollar killer coolant and pray you done blow up. please Please please help me.

Carl of Nebo IL (06/26/08)
I have been using the dex-cool coolant. And have been experencing difficulty with my car for a long period of time. And have came to the realization that dex-cool coolant that I have been told to use in my car is causing problems.

Dallas of Anacoco LA (06/25/08)
i bought a second hand 1998 chevelot tahoe from an individual and suffered from the same coolant system failures that i have been reading about.. i changed an water pump. 2 freeze plugs that had coroided and within a month of that i had to have the intake gasket replaced.. which was without a doubt the first thing that failed due to the coolant used and it caused all the other problems... on another note i have owned a 1990 gmc pick up, a 1992 chev. suburban, a 2003 chev. cavalier and a 1998 chev.tahoe.. i have had to replace the fuel pumps in every one of the and the 1998 tahoe twice... i believe that GM fuel pumps which are located in the fuel tank and are very expensive to replace are a company defect. i know several other individuals that have had the same problems with GM vehicles ranging from 1996 to 2004 year models.... coolant system failures (water pumps and or intake gaskets) and fuel pump failures.. i still like GM products in spite of the problems i just wish they would off set some of the cost to reapair by at least supplying the parts to replace the ones that are factory defected or inferior. these part failures are way to common.

Merrill of Long Pond PA (06/25/08)
My 2003 Impala uses DEXCOOL in it and so far since I have owned the car it has turned into a mud like solution and I had to pay to have the system flushed and the car has less than 90,000 miles on it

John of North Royalton OH (06/25/08)
I have a 2002 Chevy Impala and had to replace the Intake Manifold Gasket and Coolant Level Sensor in 2005. The car only had 31,139 miles.

Aaron of Nebo IL (06/25/08)
i found out today that dex-cool is bad for any one's car. and i have been using it a lot in last couple of years. and have been fixing my car every so often.

sometimes my car won't even start. i smell antifreeze just driving down the road. Antifreeze leaks.

Lisa of Mission Viejo CA (06/22/08)
I own a 2002 Chevy Venture. Over the last 12 months I have had non-stop problems with coolant-related issues. The car first began to overheat and we replaced the radiator and intake manifold. We continued to find coolant leaks and replaced parts as our mechanic deemed necessary. Recently we found out that there is a leak in the head gasket and the repair cost is $2200. We have already spent over $5000 in repairs on this car over the last 12 months and are now going to junk it. (Other problem included replacing the fuel system.) Our mechanic believes that all the coolant problems are related to Dex Cool.

Carla of Morganton NC (06/20/08)
I have a 2000 Buick Regal, currently it is not running. The check engine light has continously came on and eventually the car just stopped. I've spent 500.00 + to have repairs made including the gasket covers and it the light still continues to come on. The catalyst converter seems to be the problem.

I'm wondering if this is related to the problems everyone else is having. I have had to go in debt for another vehicle until I can have it repaired.

Malinda of League City TX (06/19/08)
I purchased a 2003 Pontiac Grand AM in December of 2002. I have maintained it very well. Last year, around 80K miles, I started having problems with it over heating. I can't list all the things that have been replaced on the car. In February I took the car to a mechanic. He looked that the nasty gooey residue that was left in the cooling unit, hooked up the car to the diagnostic machine, which did not detect that there was a problem with my car, and told me that there was a possibility that there was a cracked head gasket or motor clock. Even if that was not the issue, just to remove the motor was costly. Of course with the way shops are now days, I took it to another reputable shop for a second opinion. Same thing. This repair place stated that several people had brought in their GM cars with the same issue of continuous overheating and that it could be due to a blown or cracked head gasket, or cracked motor block. After searching around, I found a shop that would completely rebuild my motor for the amount that it would be to repair the head gasket or motor block. I had the motor rebuilt. After the repairs, the car ran fine all of 4 days. Back again was the light coming on saying low coolant and the car running hot. Finally I looked online to see if there were any complaints about Grand AM's overheating, and found all these problems that people were having with the dex-cool. Of course all the problems that were listed were the problems I was having. One article I read stated that GM contacted the dealerships and the dealerships were supposed to contact the consumer. It also reported that GM was handling things on a case-by-case basis. I never got any such notice. I now read that GM is telling people, in so many words, SOL.

Steve of Boulder CO (06/19/08)
The original intake manifold gasket design for my 1999 Olds Silhouette 3.6 liter engine is a plastic gasket. At 70,000 miles this gasket deteriorated and I needed to have the replacecd... $1400 Olds service center charge. I recently completed a 1200 mile vacation with this vehicle & now at 104,000 the gasket is again leaking. The design of this gasket is inferior.

Amanda of West Deptford NJ (06/17/08)
I own a 1999 Chevy Venture and have reoccurring problem with keeping antifreeze in the system. I have tried several mechanics to alleviate this problem. My current mechanic has stated that the reocurring problem can be a result of the dex cool coolent. My latest bill will be around $800.00. Is there any reimbursement for me? I am hoping that there will be no more expenses due to the dex cool and I love my venture.

David of Waterville ME (06/17/08)
In the early fall of 2003 my wife and I bought a 2002 Olds Alero coupe with the 3.4 V-6 engine, it was a GM Program car with less than 15K miles. The car performed flawlessly until about 40K when I began to notice coolant level dropping over a period of a couple weeks. I simply topped it off. There was no indication of a problem. At 41K, my wife started the car to go to work and the motor made a noise like there was no oil reaching the top of the motor. I checked the oil level--that was ok, so I restarted the engine the noise came back, but it only lasted a few seconds. I called a repair man (not GM) and I drove it to his place. It was there we discovered that the intake manifold was leaking slightly at both ends. However, the noise I described indicated an internal problem. I had him remove the intake, that is when we discovered that the gaskets had failed and allowed coolant to enter the valve line, mixing with the oil and turning what used to be oil into a black, nasty GUNK!! I called GM and all I got was a big run-around. The end result is the top-ed being rebuilt at my expense ($2500.00+). GM said it was a simple part failure and since it was way past the warranty period, they could not help. I have bought my last GM product.

Robert of Chesaning MI (06/13/08)
1999 Pontiac Montana - Replaced Air Intake Gasket - Replaced Head Gasket - Replaced Radiator All prior to 100,000 miles, due to Dex-cool. 1998 Chevy Lumina LTZ - Replaced engine due to Air Intake catching fire. At 108,000, due to Dex-cool. 2003 Chevy Impala - System is completely jelled up and need flush. No telling what damage has been committed. At 120,000, due to Dex-cool.

Rebecca of Caruthersville MO (06/12/08)
I have a 1997 Pontiac Gran Prix and have had overheating problems since I bought it in 1998. Is there any other coolant I can use besides Dexcool?

Raymond of San Antonio TX (06/11/08)
DEX-COOL & GM Cars I have a 2003 Chevrolet Malibu with about 80k miles, this vehicle had a tendency to run hot. In Feb 07 I took it to the dealer for a check up and repairs, I was informed that I had a coolant problem. The GM Dealer claims the repairs to the coolant system were repaired. Since that time I have twice had coolant problems which have cost me lost wages, loss of employment not to mention -- money. Recently, I came across an article in Parade Magazine, identifying a Class Action Suit against GM because certain vehicles, of which mine is one, were experiencing coolant problems. Specifically with the Dex-Cool coolant. I spoke with a representative identified in the article and was informed that reimbursement offered did not come close to the actual cost of repairs. As luck would have it, immediately prior to discovering the article my vehicle began to run hot and was in for diagnostics and repairs. The problem identified was a coolant problem which, had over time melted and warped other parts of my vehicle. The cost of these continuous problems has been huge. I lost a position that was very difficult for me to obtain. I lost my only source of income and still, I had to pay the cost of the repairs and am still without a vehicle. In my opinion GM has failed to accept responsibility for what seems to be a manufacturers defect.

Jerry of Ooltewah TN (06/11/08)
over heating, coolant system gone out

had to have rear intake manifold gasket repaired, fixed the coolant system several times

Debra of Ooltewah TN (06/11/08)
had to replace rear intake manifold gaskets, air conditioner fixed x 2, fixed over heating lots of time and had less than 70,000 miles the first time I started having problems. The paint job has peeled almost all the way off on all these cars.

rear intake manifold gaskets, paint peeling off, air conditioner fixed x 2, loss of radio due to never given a code to enter once the battery was disconected while working on the car

Terry of Selmer TN (06/11/08)
This is not a complaint. This is not a plug for GM. I have worked extensively for over thirty years on General Motors Vehicles, as well as just about every other piece of machinery that we created. Working in the Automotive Service Industry and being a Consumer as well has taught me that a lot of the information given as Manufacturer's Suggested Maintetnance has not been followed by service technicians for the most part, and refused by the consumer. I have found specifically over the years, several incidents of pure neglect on the part of the consumer that accelerates the end of the engineered life of a vehicle. With proper maintenance, I have seen these suspect engines go 500,000 miles. With poor maintenance, well 36,000 to 40,000 miles is a long time. We tend to go after the big guys to ease the pain of our own neglect. Nothing last forever. I realize that it is difficult to make payments on a vehicle, and suffer the cost of maintenance, and the cost of fuel within the same paycheck. Ford has it's 3.8L Head gasket leak problem, due to lack of maintenance, or incorrect installation procedures, as well as Chrysler's numerous leaks and failures with it's we can't decide if we want to be Dodge, Chrysler, Mercedez, Mitsubishi... mentallity. All manufacturer's have their problems, whether automotive, medical, residential, and on and on. However, remember that we the comsumers drive the market. Waste not, want not. It is a matter of supply and demand. Don't put all the blame on THEM. Take a look at your practices. Plainly put,if you don't flush you toilet, it is going to get dirty. Clean it, repair it or replace it. We build them, we buy them, we make a living with them, they carry the most precious cargo in the world, our friends, families, and most importantly our CHILDREN, who can grow up to build a better product, and a better world. SO TAKE CARE OF YOUR VEHICLES! If you can't afford to maintain it, buy a Bicycle. Consequently, bicycles have a maintenance schedule too. Just food for thought.

Dennis of Redding CA (06/10/08)
I purchased a Chevrolet Baretta with a V6 engine new in 1996. Shortly after the warranty expired the cooling system problems began. The intake manifold gasket was leaking and was replaced by the Dealer service Department at a cost of $1000. That was only the beginning. I have went through another gasket repair 5 years later and it's leaking again. I have had a rod knock since the first repair due to coolant in the oil. I have also had to replace the water pump six times along with the radiator and thermostat. That is $4 or $5000, probably more, in repairs and the second manifold gasket happened on vacation that was another several hundred dollars in travel expenses waiting for the repair to get done. The car is now 12 years old I would have gotten another car instead of fixing the 2nd manifold gasket, however like I said I was on vacation and stuck miles away. It is leaking again and for some reason I was looking into another GM car. Never again. This has been a problem with Dexcool and GM since the mid 90's and it continues to be one. In my study of used vehicles I found a lawsuit settlement for the manifold gasket problem. At 40% of $800 it would only be about $300 on $5,000 worth of repairs but it would be bedtter than nothing. Without the original paperwork it is probably a moot point unless I am still in the GM data base for the first dealer repair. Dexcool was supposed to be the 100,000 mile coolant that's if you don't have to replace it everytime the cooling system needs repairs because of it.

Dawn of Sunland CA (06/10/08)
STRANDED - My First GM - Original Owner 1999 Cutlass Oldsmobile - Nothing but Grief. I purchased this vehicle brand new. At approximately 40,000 miles I was stranded on the freeway missed 2 days of work and incurred room and board expenses. I was stranded and stuck with due to overheating and had to have the thermostat replaced due to the DexCool coolant crystalizing. A month later I was dumping more monies while still making car payments and had to replace the intake manifold gaskets and another thermostat. I am just beside myself to monitor coolant and overheating. This is just wrong! GM and Dexcool need to Step Up To The Plate take responsibilty for the stress they have caused soooo many people.... Stranded on the freeway 4 different times. Now today I have been informed that I am looking at a repair that ranges from $1800-2500 and if the engine block is cracked a new engine cost. I am now without transportation to work, due to this coolant sludge that is all throughout the engine and the mechanic has informed me of the need to replace the HEADGASKET and that there is potential that the ENGINE may all together need replacement. I spoke with GM today and they blame it on Dexcool. GM has had no problem endorsing the Dexcool sticker on their engine and Endorsing Dexcool as the only coolant to use. I do not have the funds to pay for this extensive repair and I am outraged, this has been an ongoing issue especially as first time owner and an original owner.

i have a 99 pontiac grand am which is told that i was to use dexcool with my car!

i have had 3 blown head gaskets about to have to get a 4th replaced; With the car only having 76,000 miles on it!

Jacqueline of Hebron KY (06/08/08)
I have a 2002 Oldsmobile silhouette,I have since spend approximately $2000.00 to fix dex cool system .Every year I am spenting an extreme amount of dollars on repairs .My engine is over heating again GM said they cannot do any thing about it.

Dustin of Catawba VA (06/07/08)
My Chevrolet S10 came with Dex-cool in it from the factory. About 2 years ago i noticed i wasnt getting heat from my vent, when i went to check everything out i noticed a rusty colored substance with a mud like consistancy in my radiator. i flushed it and replaced it with green antifreeze, last week my truck over heated and the problem was even worse this time.

My truck overheated, my heater core is gummed up, replaced thermostat twice, i payed a mechanic to flush the system 3 times and the coolant is still murkey brown. I am probably going to have to replace the heater core, water pump and radiator if this problem continues.

Robert of Dayton OH (06/07/08)
GM Pontiac Grand Am intake manifold gasket has to be replaced at a cost of $900 and the mechanic and blogs say this is a GM problem with Dexcool that GM settled for to reimburse customers affected.

Shannon of Joplin MO (06/03/08)
My 1999 Oldsmobile calls for only Dex-cool for the coolant system. it has since turned to sludge despite flushing and renewing coolant. This has built up on my engine parts and I know will soon destroy it due o clogs and erosion.

Tabatha of Joplin MO (05/29/08)
My 95Chevy S10 truck has given me nothing but problems. First off, head gaskets, then the motor completly blew. I have only had the truck a couple of months. I bought it from another person and about 5months after I got it it blew up on me. I just found out about the claim and would like to be involved if possible. My truck has cost me over 3000 so far for repairs. This is not including the newest engine and installation. Is there any options for me?

Keith of Troy MO (05/27/08)
I own a 2001 Chevrolet S10 Blazer. I just spent over $1400 in repairs to replace the heater core and intake gasket. I just recently received a class action suit letter against the DexCool antifreeze becasue it causes these repairs to be needed. My 2001 Blazer however is not included on the list. It stops at 2000. It should include mine as well. I also own a 2004 Monte Carlo that IS on the approved list, but it has not had any repairs yet. It still has low miles. What should I do about it? How can I get my Blazer included in the suit?

Robin of Maple Heights OH (05/26/08)
I've had several problems with my Pontiac Aztec as a direct result of DexCool antifreeze. I couldn't pass my emissions test due to engine light continuing to stay on. Even after I had diagnostic tests on my car the mechanic still couldn't figure out why my engine light continued to stay on. I ended up spending over $500.00 to get my car repaired so I could pass the emissions test and get my license plate sticker. My engine light was still on. They ended up giving me a waiver due to the amount of money I spent on car repairs. On May 22,2008 I took my Pontiac Aztec to the shop because I was having the same problem and more. My engine light was on and my car was overheating. The mechanic diagnosed my car again and told me I needed my intake manifold gaskets replaced, coolant temperature sensor, themostat and gasket replaced. He told me the cause of my problem was DexCool antifreeze. I had to take a week off of work ,because I have to have an automobile to work, and pay over $800.00 for car repairs all related to DexCool. How can I get reimbursed for my expenses or who do I contact.

Scott of Amity Harbor NY (05/22/08)
My 1999 chevy Tahoe had the head gaskets redone at 45,000 miles from chevy. I maintain this truck extremly well. Recently my intake manifold gasket let go causing antifreeze to go into the oil which the motor devloped an engine knock(crankshaft bearing. I had a certified jasper installer put in a new engine. I was then told about a class action suit. with dexicool. How do I get invovled with this between the head gaskets being done 2x's and a new engine this has cost me 6,600 dollars .

being with out my car for 8 weeks in total and approx $1,600 for the first head gasket replacement from huntington chevy, $850. for the 2nd head gasket replacement. $4,500 for a complete engine from bridgewater motors.

Joseph of North Ridgeville OH (05/21/08)
MY Heater Core is shot due to the Dex Cool coolant which corroded and clogged the core. No Heat during winter.

Kenneth of Victorville CA (05/20/08)
February 6, 2007 we had our 2003 Buick LeSabre serviced. At this time we were informed that the upper intake gasket was leaking coolant and we should have it repaired. We declined at this time as the estimate was $410.00. The car had 57,006 miles. We were never informed of the Dexcool brand of anti-freeze that was being used in GM vehicles and this product was wearing the manifold gasket. We had our vehicle serviced on 4/30/08 and the upper manifold gasket was replaced. We were still never informed of the problem that Dexcool was causing to the gasket. Our grandson had his Pontiac Grand AM serviced today at a different facility and was told about Dexcool and the problem it is causing to the upper manifold gasket. He was also told to go online and search Dexcool as there may be a reimbursement from GM to have the gasket replaced.

GM should have had a recall on these gaskets or at least informed the owners of these vehicles. We had to pay for the repair/replacement of the manifold gasket and now our Buick has 70,179 miles and GM won't reimburse for vehicles over 60,000 miles. If we'd had known about this problem in Feb. 2006 when the car had 57,006 miles, we could have had it repaired then,prior to the 60,000 limit.

Ron of Saginaw MI (05/18/08)
I have a 98 Buick which uses Dex Cool anti freeze. I just had to spend $750.00 for repair, as the buick dealer said my anti freeze was leaking, due to the chemicals used in the Dex Cool used in GM cars. The chemicals had eaten the inner seal, and they had to take many parts out of the car to replace the seal, plus new anti freeze. While waitng for my car which took half a day, two other people came in with the same problem. Is there any way I can get the company to refund the money I had to spend because of their bad anti freeze?

Victoria of Pittsburg CA (05/18/08)
Had to replace head gasket and heater core because of Dexcool ate through the gaskets in radiator.

Nancy of Romulus MI (05/14/08)
Hi, All your stories sound familiar. I was adament about changing the oil and taking care of my Pontiac Transport SE Minivan. Adding Dex-cool became a common thing and it was expensive. I kept a mixed gallon in the back cuz it went....where? It is a closed system, or at least it supposed to be. I replaced the radiator at 27,000 miles. The water pump at 45,000 miles. Adding coolant all along. At 102,000 the head gasket blew and I had to buy a new engine. Guess what....I had to continue to add the dex-cool within a week of replacing the engine! I'm totally discouraged. Nancy in Michigan

Maria of Morrsonville NY (05/12/08)
Subject My Car: Pontiac Bonneville 2003 Purchased new November 2003. I noticed at 3,000 miles that my car's antifreeze overflow tank was low (no leak visible on the ground) I informed the mechanic at Knight's. They refilled the holding tank with the labeled (dexcool) antifreeze. I was told this was not unusal. To my surprise early in 2004 a MFG Bulletin was mailed to my attention. Engine coolant may leak at the upper intake manifold throttle body gasket, or at the upper intake manifold to lower intake manifold gasket. This condition may result in a low engine coolant level & higher engine... I immediately brought my car and this bulletin to Knight's attention. I left the car during my eight hour workday. When I returned they claimed they changed the gasket. However, the overflow tank continued to be low or empty. Every 3,000 miles the oil was changed & overflow tank re-filled by knight's or jiffy lube. Again informed Not unusual. Regardless if my oil change was due or early- each long trip I took I would have an oil change service & holding tank re-filled concerned... as I would ponder to myself why? is that tank never on the labeled line? Presently at 76,000 miles February 2008 I had an antifreeze flush service at another garage Warren Tire in Plattsburgh. I parked the car in my home garage-no visible leak. By May 2008 I had drove the car a minimal 100 miles. I checked the overflow tank and it was empty. I returned to Warren Tire in Plattsburgh. They perform the first that I'm aware a radiator pressure test. Results: Cooling system pressure test, coolant reservoir empty. Advise Customer: Engine has coolant leak between upper and lower intake manifold. Possible gasket. I contacted Parker Chev Olds Pontiac Inc. where I purchased the car in Champlain, NY 12919-4806 518-298-8272 (622 state route 11) I spoke to Matt who inform me that Knight's has made two claims to GMC regarding my car claiming that two gaskets were replaced on two separate occasions. Both times Knight's collected payment from GMC. I feel this is complete fraud! My car is now scheduled to have Parker replace this gasket or gaskets for an out of pocket expense estimated price of $623.09 possible 10% higher if bolts break. They need the car of 1-2 days. Knight's never requested extended time with my car. The service complete by the end of my eight hour work day. Thank you for your time. Maria Haley mhaley@cvph.org

Michael of Oglesby IL (05/08/08)
Simply put there is antifreeze in my engine oil due to degradation of the intake manifold and head gaskets by Dexcool Antifreeze.

950 dollar replacement of the intake manifold gasket resulted in a waste of money . The engine is ruined.

Richard of Dade City FL (05/08/08)
I bought the 2003 chevrolet in my name and it is now in my wifes name. it was bought new it is a 2003 impala I was told by the dealer that dex cool had eaten the gasket and now the dex cool is in the oil. And there is nothing that they can do for me. they akso said they have had a number of cars with the 3400 engin. I do belive gm should make the repair as now I have no car and don`t have the money to repair it as the dealer said it would cost 41800.00 TO FIX IT

Picchioni of Willow Springs IL (05/08/08)
engine still overheating after repairs! 31,000 mile only Is DEX-COOL causing the problem?

Karen of Medina OH (05/08/08)
My 2000 Olds Alero has 20,100 miles on it & I've been told Manifold gaskets must be replaced as anti-freeze is leaking.

Wade of Denver IN (05/07/08)
I had a leak coming from somewhere on the engine, so I took it to a mechanic to be looked at. The intake gasket was eaten away from the Dex cool. I have a 2002 Chevy Monte Carlo, with 68000 miles. Is this going to keep happening?

I had to have it replaced. It cost me $400.00 without vehicle for a couple of days.

Jim of Rowlett TX (05/04/08)
I have a 2000 astro van w/86000 mi. my intake gasket leaked and my engine is being overhauled. I have dexcool I flushed it at 50000 miles and put prestone in at that time. I also used mobil extended performance, that 6.00 a quart oil. so I am not using either one of them again.

Bodie of Louisville CO (05/02/08)
My 1992 subaru started leaking antifreeze last winter.

I took my 1992 Subaru to the dealer because it was leaking antifreeze. Apparently, the antifreeze, Prestone Dex-Cool, may have damaged the head gaskets and now I am facing a $2000.00 repair bill. The dealer identified the coolant as Dex-Cool right away and indicated this may have been the cause. I bought this stuff because it was suppose to be good for engines with aluminum radiators and I even emailed Prestone and got a return email stating OK to use it in my car.

Alfredo of Anaheim CA (05/01/08)
Dex Cool is continuing to ruin my gasket my malibu is leaking coolant I already had a machanic check it out and I was given an estimate as well as the solution to the problem with my vehical. I have a wife & child & a elderly grandmother whom I am her care giver and I don't know how I'm going to provide for my family with out proper transportation I need a solution to the finances that are going to cover the cost please help?

Pat of Center TX (04/30/08)
Had another problem with our 1999 Pontiac Montana. This is the third or fourth time in recent years the same problem has occured. Vehicle requires Dex-Cool product. Gaskets have detoriated each time . This time, it will require a NEW MOTOR. Gasket problems with the Dex-Cool product, has caused us major repair. Cost this time is over $4000.00,the time prior, $1500, the time prior another $1000 . I think GENERAL MOTORS should absorb the expenses. , since we were told, verbaly and in our Manuel, to use nothing but DEX-Cool.

Charles of Westland MI (04/29/08)
Went to check about the GM Dex Coolant recall. I have brown sludge in my radiator. They said it was from a bad valve cover caused by the Dex Cool and they can't do anything about it but to contact GM. They also told me that to replave the valve cover gasket would be about $900, but GM will only pay about $400. I'm having trouble trying to join the recall lawsuit...

Michael of Linden MI (04/29/08)
My intake is leaking due to Dexcool antifreeze. My truck was a new purchase. I am now experiencing antifreeze in my oil. I have always used dexcool when Ive had it flushed they put the dexcool back in. The radiator cap went first.

Jerry of St. Louis MO (04/28/08)
I have a 2000 Chevrolet Venture. The intake manifold gasket failed in 2002 less that 10,000 miles out of warranty. A $1200 repair. Mechanic told me I'd be back. Guess what? The vehicle is heating up almost immediately upon starting again, so the problem has resurfaced.

Roger of Franklinville NJ (04/27/08)
I'm a used car dealer, I hate the dex-cool product, it completely ruins alot of the used GM vehicles, maybe they planned it, who knows, I find so many of the GM used cars to have leaking intake and head gaskets, its a real problem!

We had to fix several GM autos with head gasket problems. HOPEFULLY YOUR READERS KNOW YOU CANNOT MIX ORANGE AND GREEN COOLANTS, IT TURNS TO MUCK.

Lisa of Dundalk MD (04/27/08)
Today I had my temperture gage replaced. I have had my car for 7 years and really never had this much problems. I've used dex-cool only and this year my car reached over 100,000 miles and i am having hugh problems with over heating and my dex-cool running out. I work partime and yesterday I had to take the bus. 3 busses to get home from my partime job. I had the dm dealership checked my car today and the temperature gage needed to be replaced and the coolant reservor. I was told that the cap was not tight enoungh and the temperature gage is leaking. I always trusted gm but thanks to dex-cool. No more.

Frankie of South San Francisco CA (04/23/08)
ive spent about 4000$ because of the faulty dex-cool coolant in my 2001 chevy impala 3.4 and now i think its messin my car up again please help

Benedict of Statesville NC (04/21/08)
My 2002 Pontiac Montana is leaking coolant through a gasket. I was told that the Dex-Cool anti-Freeze is the problem. My car was serviced once for this problem already. Now I'm going to have to pay up to $1000.00 for a repair bill. Someone needs to listen to all the people with the same problem.

Greg of Fairfield OH (04/21/08)
Dexcool in my 1999 Pontiac Grand AM SE has cost me a lot of money in repairs. I have replaced the gaskets several times, the water pump several times, and have had to flush and fill at least 4 times since owning the car. The gaskets are now leaking again and I have to add dexcool on a weekly basis.

Connie of Normal IL (04/12/08)
I have a 1997 Olds. 88 that had to have extensive repairs done to it. The bill was almost 1400.00 and I feel was due to the Dex-Cool related problems. The intake gasket and upper intake failed and dumped coolant into cylinders and it locked up and we had it towed to dealer for repairs. I would like to be involved in any settlement from GM in this manner and would like to know who to contact about this. Thank You

Ed of Pensacola FL (04/11/08)
2002 Chevrolet Venture intake manifold gasket failed. At the time I was unaware of class action litigation (and potential settlement) against GM regarding Dexcool coolant and gaskets and general problems related to Dexcool.

Felicia of Swartz Creek MI (04/06/08)
I have 1996 Blazer that came with the orange coolant. Also, I have purchased a 2003 Buick Century that I have had since November.

My Blazer has always had some sort of problem with it. I replaced the radiator a few months after having it. I have replaced the water pump, a couple head gaskets, and fuel pump. I don't know if the fuel pump had anything to do with it but still it's fustrating. I bought it for 3000 and I have spent the same amount on repairs. After all those repairs, it still has problems. During the hot summer months, it cuts off at every stop light. As for the Century, it was fine until I decided to fill it with Dexcool, after reading the manual. Not long after I put it in, it started running harder and making this ticking noise. It then dawned on me, after hearing the news about Dexcool, that this was the root of my car problems. I am very upset because I have two great cars and this crap has ruined it. Who is going to pay for all this?

Cindy of Kansas City KS (04/02/08)
Purchased 1998 Pontaic Bonneville.  DexCoolant ate gaskets out twice Incurred repair bills to repair heads and engine. Made formal complaint to GM on January 15, 2001.

Phil of Overland Park KS (04/01/08)
I have a 2001 s-10 chev. blazzer with 90,000 miles. I've purchased the vehicle in 2001 since then I've replace the water pump around 45,000 miles and just replaced the intake gasket due to losing anti-freeze that damaged the gasket. My mechanic advised me that he has replaced several of these on GM products because of the coolant called Dexcool that GM puts in their vehicles. Superior Chevrolet has always service my vehicle since new and advised me of the leak but wanted a ton of money to fix it. I know GM is aware of this problem but offers no help or willing to honor its warranty. I've been a loyal customer and have always bought chev's in the past and the future chev. purchases are to. My mechanic did fix my problem for now but I'am worried about having more. Is there anything you folks can do to recover my lost money.

Rowleen of Columbus OH (03/31/08)
Bought a used car damage done to engine and gaskets due to Dex-col coolant. Over $3,000 to repair.

Denis of Inverness FL (03/31/08)
after reading complaints about dexcool causing engine problems why are they getting away with saying they have no knowledge of it ?

Doris of Pontiac MI (03/31/08)
I own a 1196 Chevy Blazer built by Gm and have used Dex Cool. I have had to replace many parts and now my engine is gone, making a lot of noise I am either going to have to replace it or purchase another car. I am retired now and living on a fixed income and this has caused me a big headache, because, I am spending money that I can't afford.

Matthew of Independence MO (03/31/08)
Electrical problems and heater core problems and lower intake maniford problems with 2002 Buick Rendevous. The car used Dexcool which GM specifically uses and caused lots of issues.

Amy of Olathe KS (03/31/08)
I have a 04 Grand Prix and my coolant light keeps coming on and going off and my passenger side floor board is always soaking wet. I took my car to O'reilys and they told me that the light has something to do with the coolant. I havent really noticed the difference in temp.. My transmission fluid was leaking and I had the gasket replaced and havent had a problem with that since but my floor board keeps getting soaking wet and wont dry and the coolant light goes off and on when its cold out.

Shelly of St. Louis MO (03/27/08)
I own a 1998 Chevy Malibu and it now has over 100,000 miles. Recently my car started leaking Antifreeze, I only use dex-cool because thats what the vehicle manual said to use and that is what any automotive place uses when getting my oil changed or a flush and fill. I was told by CarX that I needed to get my intake manifold replaced last year. After reading all all info on Dex-cool, I now know it is the problem. I had the same problem in my 1987 Transam in 1in my 1990 and my Pontiac Grandprix. I will most likely have to replace my water pump as well and get all the dex cool flushed out. hopefully I have not damaged my motor. This is horrible if GM knew this product would cause problems and i hope we the consumer can get our money back that we have spent getting these problems fixed. This saturday I'm taking my car to Car X for them to confirm what needs to be done and what will be the total cost. I cannot drive my car right now for fear that I might blow my engine. this is just not right.

Yanko of Eastpointe MI (03/25/08)
I have an 2003 Montana and the head gasket is leaking and I am @#$$%^ now I have to spend 1000 dollars or more to get this fixed I want to be reimbursed, stupid GM idiot engineers you suck! And DEX-cool BLOWS the big one.

Sandra of Warren OH (03/25/08)
I purchased my 1999 Buick Century new in 1999. I had this car serviced by Valvoline, the oil and everything was maintained by Valvoline for years. I took it in and told them my heater was only heating when I would turn a corner. After changing oil and all it still was not heating right. my boyfriend took the cap off the radiator and it was full of rusty looking sludge and foam. I called valvoline and told them I had just had my car in and I had found this gunk in my radiator and I told them since I advised them about the heating priblem they would have had to open the radiatro cap and if they did they would have seen that gunk. I was told they could flush it for me for $89.95. I called around and got a price for a flush from Zip Lube and after taking it in to have it done he told me, he has seen this a lot with GM products and he changed it after flushing. He said it might need flushed again because the gunk will keep coming to the top. my my low coolant light started coming on, and I took it in for them to check again, and it wasn't hot, he said that the sencor must be gunked up. The low coolent light stays on all the time now, and it does not overheat because I keep an eye on it. Now the heater has gone out, in the middle of winter and I will be taking it in to have it fixed. I can hear what sounds like water gurgling behind the dash which I had never heard before. From what I have been hearing, this DEX-COOL antifreeze that GM put in my car is the problem, Valvolone kept adding the same stuff all the time I had taken the car in to them and I was told that it was required. I feel that gM has done Me a disservice by putting something into my car and requiring it which they have known for years not that it was ruining cars. This should have been a recall factor many years ago before it came to this point. I am on a fixed income and don't have the money to keep flushing my radiator every year and replacing what this crap has ruined.

Robert of Central Square NY (03/25/08)
I have the same problem with my 1997 Monte Carlo as many others do. My vehicle is being worked on as I am writing this. Last week I had the water pump replaced. Today, it's the gasket. I've been reading about the Dex-Cool problem and all the repairs related to it on different websites. Each complaint seems to be describing my car, exactly. The air conditioner never worked right since we bought this car two years ago. When I had the water pump repaired last week, the guy showed me all the sludge in the radiator and said I needed to get the radiator flushed. Did that. Now it's being repaired because of the gasket. $1,000 later. If GM knows about this, then why didn't they stop this Dex-Cool Antifreeze a long time ago? My car has 187,000 miles on it. The mechanic checked out the entire car to see if it was worth getting the gasket done. He said everything is in excellent shape except for this. Do I have a choice? I can't get a used car that is in this good of shape for $1,000. But, having seven children, I can't afford this type of repair. This has pushed me even further into a financial hardship. Thanks GM!

Joyce of Hemet CA (03/24/08)
I am trying to resolve the same problem many have obviously had with using dexacool in their radiators. I have a 1999 chev. Blazer and when I open the radiator cap the coolant looks like someone threw mud in it. The radiator shop said they have experienced many dissatisfied, unhappy GM customers with the same problem. I called the Chevrolet customer assistance number 1-800-222-1020 and was told they never heard of such a complaint! After reading everone elses complaints, I can hardly believe that. The dealership told me the same thing- that it was news to them!

Jim of Melbourne FL (03/24/08)
My 1999 Buick Pk. Avenue suddenly stopped running, I had it towed to a garage where it was diagnoiced with a engine that had siezed up. The mechanic determined that the cause of this was the intake manifold which leaked and mixed the anti-freeze with the oil. I will have to have the motor replaced as well as the radiator.

Carol of Cincinnati OH (03/24/08)
My Saturn uses Dexcool, and this is the second time I have had to pay nearly $600.00 for the manifold gaskets. In fact, this time I have a leak in the entire cooling system caused by dexcool. I want my money back from these repairs!!!!! This is crap.

Dan of Rockwall TX (03/22/08)
I have a 1999 Buick Regal which I purchased new in May, 1999. I have now had multiple repairs to the cooling system. Initially I heard a noise that sounded like water 'sloshing around' inside the car dash, but only the first thing in the mornings. Took it in and the Buick dealer had to replace the intake manifold (plastic!) along with some gaskets and Dex-cool. Next time it was another gasket under the throttle body assembly that had started leaking and I was getting a 'low coolant level' warning light although there was no sign of any leakage. Just the other day, I had to take it in again and this time they said that my radiator was very clogged up and needed to be replaced or flushed ($500-$800), my heater core may be bad too and possibly some water pump problems. I had noticed that my coolant bottle was getting a red looking gunk in it but since GM literature stated that there was no maintenance required of the cooling system for 150,000 miles I was not concerned. I mean, after all, I always take this vehicle into a GM dealer for their high dollar oil and filter chanegs and get their free inspections each time and they always said the cooling system was fine so who am I to question their Mr. Goodwrench experts. I had heard of a class action lawsuit about a year ago against GM and Dex-cool damages. When I asked my Buick dealer service representative about it, he knew nothing about it, but when he called me about my many recent cooling problems, somehow the local GM service representative just 'happened to show up' at the dealership and they went over my cooling system problems with the servcie technician and concluded that all of my problems were caused by someone mixing green glyucol based coolant with the Dex-cool in the engine. I mentioned that no one other than a GM dealer has ever touched my car, but also knowing that now since I have a GM technician, a Buick dealer service writer and GM representative on record that I had green anti-freeze in my car. I am fighting a losing battle my myself. I have already signed up for a class action lawsuit but have heard that a federal judge recently ruled that there could be no national class action suit. Any class action suit would have to be on a state-by-state action. I am interested in making GM live up to their responsibilty for a faulty product and to their 150,000 mile cooling system warranty. My car has 103,000 miles on it.

Grace of Albany NY (03/16/08)
At 47,000 miles, my Malibu needed a full intake manifold replacement due to the poor engineering of the gaskets in the manifold. They are destroyed by Dexacool anitfreeze. This is a common problem with this engine and their solution was to release a new design intake manifold gasket w/bolts that have a thread locker adhesive added. You can purchase them at the GM dealership and take them to your mechanic. Unfortunately I found this out AFTER I spent $683.00 replacing the unit only to find out that in another 40,000 miles or so the same thing will happen. General Motors should have sent out letters to their car owners - I am the original owner- telling them about this problem or at least to the dealers. I think a class action law suite should be initiated.

Sandra of Albuquerque NM (03/10/08)
Dex cool in 2001 chevy malibu purchased used in December of 2007. The coolant has caused engine problems with gasket need to be replaced.

Scott of Houston TX (03/05/08)
I have also had an issue with te Dex Cool and leaking intake manifold gasket. At this point I am holding my breath and hoping that it was only the intake gasket and there is no damage to the head gasket, heads, or engine block. This leak occured in my familys 2002 Oldsmobile Shiloutte. I am very disappointed that GM would allow this to happen to so many consumers. Car reapirs and expensive. They can also be very dangerous and risk lives. An engine seizure in city traffic could cause serious injuries and even death. The irnoic thing about this is that my wife purchased the Oldsmobile while I was deployed to a combat zone. I am an Army mechanic and usually take care of our vehicles. I wasn't home to take care of our Ford Windstar and it was having a lot of issues that my wife was paying to have repaired. She was pregant and had three other children to care for so she sold the other car and bought the Oldsmobile so she wouldn't have to worry about a faulty engine. 4 years later, I'm getting ready to deploy again and will be leaving my wife with an unreliable vehicle. If she trades this one it, it will be for a Honda.

Tim of Noblesville IN (02/28/08)
Head gasket and intake manifold gasket both had to be replaced, costing us close to $2000. GM knows of these faulty gaskets and should have recalled the vehicles and replaced them all. We paid about $23,000 for this vehicle new.

Larry of Oklahoma City, OK (02/26/08)
We took our 1998 Buick Century with 41,500 miles on it to City Chevrolet in Oklahoma City and found That our intake manifold gasket had been eroded by Dexcool coolant. We are now faced with an $800.00 bill to replace the gasket, and flush the coolant system. What should have been a $30. oil change has turned into a nightmare. We want GM to be held accountable for what this coolant is doing to engines and how corrosive it is. With this many miles, I shouldn't have had to even flush the cooling system yet!!!!!!!

William of Lodi OH (02/22/08)
After spending a few days reaserching my Venture's problems on the internet, I thought that I had discovered that G.M. had put faulty intake gaskets in many of their vehicles. I've found one site that is a petition to G.M. and the B.B.B. to recall the gaskets. Another site pertains to a class action lawsuit against G.M. that has been initiated in Canada over the gaskets. Your site says that DexCool is to blame. I sure don't know what is causing the failures, I just know that I'm a two-time victim! Starting with my 1999 Venture. Had to replace the intake gasket and water pump, for about $800. within a year, a coolant leak started up again. What do I do? Well, being the dedicated chevy man that I WAS, I went out and bought a 2003 Venture! Bought it from a chevy dealer 6 months ago. I did not start driving it then, I wanted to get every last mile out of my 1999, befor sending it to the dump. I suppose I'll hang on to that '99 now, and see if any lawsuits pop up! Back to the 2003... Two weeks ago, it was finally time to start driving the new one. The heater didn't work. I took it to the dealer, whom stated- intake gasket is shot. Needs $700. in repairs. They sold me a van with a bad motor, then they want me to pay $$$. to fix it! needless to say, I left there, and do not intend to return- ever. They did fill the radiator up, and the heater DID work for a few days. when I checked the radiator, the coolant level was very low. apparently, the coolant level sensor doesn't work either. the temperature guage never said I was overheating, but the next day, the motor started knocking VERY loudly when it's cold. This vehicle has only had license plates on it for exactly two weeks now, 79k miles, and it has had a bad knock now for 3 days! If it's not overheatng damage, then it's likely to be damage from coolant in the oil, contamination. What are the damages?? I do not know yet. I'm too scared to find out, because I can't afford it anyway! sure hope G.M. is forced to own up to their mistakes like Ford had to!

Brian of Caldwell ID (02/20/08)
I own a 1998 Oldsmobile Cutlass, and just had it serviced. I was shown where the dexcool is now leaking on either side of the intake manifold, and with the coolant flush and replacement of the coolant with the reliable green coolant, plus replacement of the thermostat, it will cost a measley $1,000. This vehicle only has 68,000 miles on it. I have already personally replaced the intake manifold and water pump on my daughters 1997 Saturn. I was looking at trucks now that I am near retirement, but I will never own another General Motors product and will purchase either foreign trucks or a Ford. I will keep my receipts in case General Motors ever does loose a case or a class action suit as far as dexcool erosion is concerned and maybe one day I will get my repair costs back.

Cainon of Morenci MI (02/18/08)
I own a 1999 chevy silverado. As it has been a good truck in general i too want to voice my complaint on this coolant. I have now had 2 heater cores put into this truck-at a cost of $850.00 each time. I purged out the dex cool for the old green stuff because i could see mud and crud all over in my coolant system.

First of Augusta GA (02/18/08)
We have a bus with a GM chassie that has Dex Cool in it. We have 48,000 miles on the bus. We are beginning to experience problems with gaskets and the radiator is gummed up. We are looking to pull the radiator next week and attempt to save it. We will flush the system and replace the Dex Cool with conventional fluid. Our prayer is that further damage can be avoided.

Richard of Appleton WI (02/16/08)
My 1998 Oldsmobile Intrigue has Dex Cool for antifreeze, I've fixed major gasket leaks twice, and had to replace the intake manifold, which had large pits in it, and was junk. I've never seen a intake in that bad of shape. My Pontiac has had gasket problems, and so has my son's Chevy, all have Dex Cool.

Carman of Deltona FL (02/15/08)
My car was leaking coolant. I took it to Firestone Auto service and to have a coolant flush done and was told that I needed to have the manifold and gaskets replaced. So today my car is in the shop, when they started doing the job they found that the water pump was bad. Also the the plugs need to be replaced. The guy told me it is just snow balling. Not sure what else they may find.So far the bill is $1,100.

The Gaskets, water pump, and Manifold intake set had gone bad because of Dex Cool as per Firestone Auto Care technician

Thomas of Chelsea MI (02/14/08)
I have a 1996 Buick Century. Despite what the GM dealer has said Dex Cool has caused many problems in my vehicle. Sludge started at about 20,000 miles, I have had to flush the system about ever 10,000 miles, replace intake gasket, and water pump. I have talked to trusted mechanics and they said Dex Cool is the problem. My car currently only has 73,000 miles on it. I switched to a different coolant and the vehicle runs much better, but I believe that the damage has been done and problems will continue to occur. It would be nice if GM would fess up to their faults, since from what I have seen and heard, this Dex Cool problem covers many years of production vehicles on the road today.

Rod of Huron SD (02/13/08)
I have a 1997 GMC Jimmy and started having problems with it overheating. It had dex cool in it.

Robert of Mercerville NJ (02/12/08)
My daughter goes to school at University of Iowa. She has a 98 chev. calvalier. The car started overheating. I told her not to drive it when the temp gauge reads hot. I said she should take it to the chev. dealer nearby thinking the problem is just a stuck thermostat. The service manager told her they would diagnose it. He also said the fee would be $88 cause that is what the labor cost is per hr. The car was there 8am. the next morning. Not hearing from the service manager all day she called at 5pm. He said they were just bringing it in and couldn't diagnose it till tomorrow. I finally called him around 12pm the next day and was told the car had a warped cylinder head and the cost for repair would be $2,250. The car never had an antifreeze leak that my daughter ever noticed. Ifound a couple of other repair shops in the area and asked one of them for a second opinion. I called the chev dealership up and told them that was to much money to put out on a 10yr. old vehicle. The manager said fine and she could get the car after she pays the bill. A few days later she took the car to the other repair shop and left my phone # with them. I recieved a call within a few hrs. The owner of the repair shop said he has gone over the car and can't find a thing wrong with it. He thought maybe I was confused about the warped cylinder head. He said sometimes the thermostat gets stuck and the car will overheat. Just what I thought. I told him what the dealership said and he said that definetly was not the case. He asked me if he could change the thermostat and the temp. sensor. Isaid yes. He kept the car another day and everything seems fine. His bill was $230 a lot less then the dealership rippoff would have been. This fellow was courteous, kind and honest. I always thought that dealership service was honest and accurate. I own 4 GM vehicles and will never take them back for dealership service again. For them to try and rippoff a young out of town college student telling her she needs all kind of work done on her car when its only a minor repair is TERRIBLE.

William of Wasilla AK (02/12/08)
GM Antifreeze has corroded and destroyed the heater core and other parts of my daughters 1998 blazer, despite the vehicle having only about 30,000 miles. I have been to multiple GM dealers who all denied there was any association with their coolant.

Thomas of Galloway NJ (02/11/08)
Sludge in radiator...had to have replaced. Manifold gasket had to be replaced also. Had transmission replaced. Could they have been a result from using the Dex? Again having transmission problems.

Brenda of Lake Orion MI (02/10/08)
I too am a victim of having a very costly repair on my 2003 Buick Rendezvous because of DexCool. Last month I noticed my car had a leak. I first thought it was transmission fluid but when I took it in to have it looked at I was told it was coolant that was leaking and that my head gasket needed to be replaced. I had no choice but to fork over the $2000.00 it cost for the repair and they needed to keep it for 5 days to complete the job. I knew nothing about this problem until I started to do some research online. I'm disgusted at GM for not doing a recall. I know there is a class action lawsuit against GM and their use of DexCool in the state of Missouri. What about other states? Something needs to be done. I always believed in buying American made cars. Not anymore after this. No wonder the American auto industry is suffering.

Rebecca of Reading PA (02/07/08)
i had a 1998 pontiac grandam and got rid of it because intake manifold gasket was bad. ithan bought a 1998 buick century with in 6 month it to started to leak .i reasearched and found out it was a common problem with gm .i contackted gm and was told take it to the dealer .the dealer confirmed it was the intake gasket and it would cause me 700 to fix. so with no other options i paid the 700.i thought this was the end of my problems nope 2 months later it started to leak again took it back to dealer was told it was anther gasket it would cause me 700 more.at this point i couldnt afford it so now i have no car.gm should recall this but they wont when i called them they denied it was a known issue

Sale of Honolulu HI (02/04/08)
After reading the instructions in my vehicle's owners manual, I proceeded to follow the books advise by adding this antifreeze to my vehicle, but it wasn't long before the low coolant light started flashing again and now I believe there's a problem with my cooling system, so I searched the internet and to my suprise, there is an article warning GM car owners of using this type of antifreeze. I never knew about the law suit but now I would like to add my name to the list.

Poor engine performance, costly repairs, psychological stress that I've been through because of this product.

William of Waynesboro GA (02/01/08)
I purchased my 1996 GMC Yukon SLT with 5.7L engine new in April of 96. Within 20K miles, I could smell engine coolant, and the fluid in the overflow tank was turning dark. The dealer flushed/refilled the system. At 35K miles the same thing happened again, and the dealer repeated the flush/refill and replaced the radiator cap. At 60K miles, coolant levels began to drop, developed a rusty color and brown sludge--so had to repeat the procedure (with Dex Cool) at my expense. Finally at 80K miles I got smart and went with the tried and true conventional green antifreeze.

Unfortunately, the damage had been done, and today, at 112K miles, I'm fighting the slow (1 gal. Every 5K miles) internal leaking of coolant using various leak-stop products; but afraid I'm fighting the inevitable of complete head and intake manifold gasket failure--along with failure of water pump, radiator, and heater core. Fortunately I have the ability to perform needed repairs myself. GM has done a tremendous disservice to their customers by not producing a quality product nor admitting to the problem and offering a reasonable fix. Too bad CUSTOMER LOYALTY doesn't mean anything to GM. I love having an SUV, and soon it will be spelled TOYOTA Land Cruiser.

Alicia of Marana AZ (02/01/08)
My husband owns a 2001 Chevy Silverado, and we just got it back from the auto repair shop where we had to have the water pump replaced. The mechanic (a friend of the family, so no worries about him fixing things just to make money) said that the DexCool corroded the gasket, and the water pump had to be replaced. He also insisted that we flush the system and no longer use DexCool, which he referred to as that orange [expletive] in the truck. Knowing he had our best interests in mind, I gave him the green light to fix the problems. $430 later, I can only hope that this was the extent of the damage done by DexCool. We will now only be using green coolant in our vehicles.

The repairs cost me approximately $430, including tax and labor.

David of Chicago IL (01/30/08)
Spent over 300 dollars replacing faulty plastic intake gaskett on 2001 Chevy Malibu 7 months ago. Now vehicle is again losing antifreeze through blown head gasket.

T of Union MO (01/29/08)
This is a follow up to a previous posting I had made about my issues with the coolant system (and other odd, unexpected repairs).

I was informed today by the local dealership that $1000 will fix my current problems because I had 2 leaks in my lower intake gasket. And, for another $500, they are having to replace my driver's hub assembly because it is loose and worn. Still yet, a 2002 model Pontiac GP SE, little over 5 yrs old and at 91,000 miles, I'm sadly disappointed and am being drained financially from starting over with another vehicle. I do trust this dealership because they did good faith work in April of 2007 for my bad catalytic converter, which I neglected to mention in my last correspondence, that went out just a couple hundred miles past the 80,000 mile warranty. See...one bad turn after another on the road of life with General Motors these days. And, I have all the repair statements to show it.

How do I get on the class action suit against GM & On Star. GM sold me a Avalanche 2500 3/4 ton 2002 They are not making that 3/4 ton anymore and I can not get the ON Star Up Grade I am a 100% disabled Vietnam Veteran I need both those issues for safety. To me I payed $40,000 for false advertising, please advise me should I take this civil if there is no class action suite T

We are using Dex Cool in our chevy malibu..as recommended by GM, and now have damage to the engine.

Suzanne of Lake Orion MI (01/27/08)
I am also one of those GM owners with the replaced Intake Manifold Gasket,and My Water Pump replaced too. Now I found out that my Head Gasket has a crack in it and is leaking Coolant into my oil. I own a 1996 Pontiac Grand Prix SE, the car is 12 years old. It was given to me by my deceased Parents. This car means the world to me and I am worried sick that I will soon lose it if the Head Gasket blows. It burns me that a big Corporation like General Motors are so blind, deaf and above all stupid when it comes to taking care of their customers after they buy their products. This type of nonsense has been going on for years and years. All GM thinks about is the BOTTOM LINE.

I am having problems withthe cooling system,using DEX_COOL.At presant I am haveing intake gasketsreplaced on a 1997 chevy S10 blazer with the 4.3 engine.I had changed the coolantabout 4 years ago.The vehicle has 128900 miles.I am hopping that it did not ruin my head gaskets. My mechanic who I have used for several years said this is the most corrisive collant he every ran across. Also been told this by othermechanic and auto store personel I am on disability and did not need this problem.I had 2029500 miles on my 1988 blazer S10 with the green coolant.and never replaced an gaskets

Intake gaskets needs to be replaced ,and maybe the head gaskets.I hope the rest of the drive train are ok.

T of Union MO (01/26/08)
I purchased my '02 Grand Prix in 2002. It was a program car and upon the first oil change, the service shop showed me the sludge from the Dex Cool. Within two years, on cold days, my low coolant light would come on indicating I would have to add more. This went on until the beginning of 2007. After receiving the class action notification and consulting several service techs, I made the switch to the traditional anti-freeze. That was great until October 2007. As would luck would have it, the day I made my last payment, my check engine light came on and that cost me another $275. I was told the system did not look like it had been flushed properly when the switch was made and that it had to be done. I was also told I needed a new thermostat. It's now January and I'm experiencing problems. On a bitter cold day, my car's temperature was fluctuating up between 160 to 210. It would not produce warm heat in the cabin. When I called my local service shop, they suggested that it may be the intake. Looks like, according to other's testaments, that it may cost me up to $1000 for something like that. I've been a pretty loyal GM and Pontiac owner, but this car has failed my expectations. I had the entire front end replaced before 36,000 miles due to rack leakage and bad wheel bearings. I've had a fan relay go bad. The stereo display acts up on some days. It keeps blowing the bulb in the rear window brake light. And, now the coolant. I also know a co-worker who just had to have a new engine in their Envoy because of the Dex Cool situation. How sad when their vehicle was even newer than mine. I ask what's next for GM?? Or maybe, I shouldn't ask and just get rid of it before the nickels and dimes start!

Kenneth of Lock Haven PA (01/26/08)
I have a 1999 Pontiac grand am and i fouund out that the antifreeze was leaking onto the garage floor. I took the car to anastos brothers and they had to replace the intake manifold. This is the second time this has been replaced because when i first purchased the vehicle and it was under warranity McEndtyre also had to replace it. About two months later i had to get the oil changed in my car the mechanic found out that there was sludge in my oil. I then again took the car back to Anastos Brothers at which time they then again tore the engine apart and had to replace the engine manifold. Two weeks after taking it there and getting the manifold replaced the car was heating up and i took it back to anastos brothers and they had to replace the head gasket and the intake manifold again, they also had to flush the engine. The car has started to make a loud tapping noise and is now going back to the garage for furth3r repairs.

Karen of St. Louis MO (01/18/08)
Purchased a 99 Chevy Blazer for our daughter for college in October 06. At 84,000 miles started leaking antifreeze and the repairman said the antifreeze looked like sludge and this is a common problem with GM vehicles. Had to have intake manifold gasket replaced to the tune of $700.00. At 85,000 mile had to have the heater core replace to the tune of another $731.00. This is unacceptable and we will never buy another GM product nor will we let any of our 4 children buy one either. I have a 98 Ford F-150 Econoline van with 180,000 miles on it and have not had half the problems with this GM Blazer. It is a piece of junk. What a shame

Mark of Meridian ID (01/17/08)
Hello, I would like to comment on the Dex coolant issue. I have read all the complaints because I just got back from having my system flushed. (I would like to caution you all about shops taking advantage of you and charging you for things that were not needed.) Let me explain. I paid to have my system flushed and thermostat replaced at Midass suggestion because my heater was blowing cold air. $230 they charged me and it did not fix the problem. There was a happy ending to this story because when I took it back they flushed the system again and my heater is now working. Some shops may tell you that you need work that is not really needed. For instance your heater core may be plugged and instead of replacing it you may be able to flush it. In defense of my statement about shops telling you things that are not true, I had Brunel Tire Factory replace my front differential seal two times and now for a third time this weekend. The last time they told me I had a coolant leak and led me to my truck to show me. Low and behold they show me a green trail of coolant dripping from my engine. It is a good thing I did not fall for it and only because it was before Christmas and I could not afford the money It was only when I took my truck in to have it flushed that I realized I do not have green coolant it is orange or red coolant I will leave it up to you to figure out how I happened to have green coolant dripping through my engine Anyway, I have not had the problem with leaking gaskets as many have had and I will not say that your leak was not legitimate. I will say however that I will be flushing my system every two years at least because I think the Dex coolant may have a tendency to gum up easier if it is not changed out more frequently. Regards,

Joe of Wichita KS (01/16/08)
2003 Pontiac Aztek overheating, engine hot light comes on ,Antifreeze sludge 2001 overheating ,low coolant light comes on ,smell burning anti freeze.

Sharon of St Louis MO (01/15/08)
I have a 97 Lumina and of course used the Dex cool per Chevy recomendations and had to have extensive repairs done to my car. Not only did they have to replace the gasket, but they had to replace the manifold and the head.

Albert of Bloomington IL (01/15/08)
dexcool ruined 1996 gmc jimmy engine.

Fletcher of Arlington TX (01/15/08)
At 85k miles my car started getting hot, smelled coolant, and idled rough. Mechanic just called me and told me coolant in cylinder due to intake manifold gasket. Since then i have read all kinds of complaints and come to find out, GM knows dex-cool causes this issue, yet they want to take no responsibility for it. How is there no RECALL at this point. Issue is going to cost me around $1000 to fix. Anyone ever gets a class-action; I'M THERE WITH YOU because this is ridiculous.

John of Kansas City MO (01/14/08)
On January 11,2008 during a maintenance service checkup at Midas Auto Service Experts. I John/Shirley Douglas was inform by a Midas Technician, that our car manifold gasket has failed under it's coolant systems, it has been leaking and running out and building up around the car's engine block, and that is the cause of the burnt fluid odors...

Greg of Pinson AL (01/14/08)
I carried my 199 Pontiac Grand Am GT to the shop two weeks ago and had to have an intake manifold gasket installed. The mechanics, who I have used for years, informed me that it was the dexcool antifreeze that ate through the gasket. My car being older it took it as part of car ownership. A week later, I took my wife's car in, same exact problem. Both cars cost me $2000.00 that I could not afford. I went to do some service on my dad's Pontiac Montana and the reservoir was empty. I haven't gotten his into the shop yet but I wouldn't be surprised if it is leaking also.

Fhad of St. Ann MO (01/11/08)
My dex coolant isn't to be replaced yet but it is already steaming and overheating.

It is destroying my engine.

Gary of Prattville AL (01/11/08)
I join the ranks of dissatisfied GM customers who've had problems with Dex-Cool anti-freeze. The Dex-Cool in my 1999 Chevy Suburban destroyed the water pump and intake gasket allowing coolant to flow directly into the engine block. The coolant did not last as long as advertised - ~95K instead of 150K, and I understand it actually laster longer than most other people who've experienced the same problem. The question still remains - why would the manufacturer continue to use a product they know is so corrosive? Bottom line for me: although I love the Chevy Surburban, my next vehicle will not be a GM product. Can you say, Honda, Toyota, or BMW?

Greg of Lindsborg KS (01/08/08)
2001 Chevy Monte Carlo with 56,000 miles leaking Dexcool from intake manifold! Known problem by General Motors! GM will not help cover expence of this known problem they are having with many many GM vehicles!

Sheryl of West Bloomfield MI (01/01/08)
GM has had a lot of class action suits claimed against them for a faulty gasket. This has caused thousands of auto owners costly repairs. I've been searching the internet and found several sites with these two issues: Dexcool antifreeze and a faulty gasket. Apparently, the anti-freeze and or the gasket is the culprit. I have that problem in two vehicles.

Jeremy of Boise ID (12/31/07)
In Feb. 07 I found out that my 96 Pontiac Grand Prix had a leak in the lower intake manifold gasket and was leaking coolant into the oil. The car had close to 130,000 miles, so I wasn't all that surprised. I performed the work myself and saw that the heads were pitted where the manifold sits. That's when I read about the complaints about Dex-Cool. During the same month, my co-worker with the same car also had the same problem. My aunt has a 2000 Chevy Malibu that also had the same issue.

I recently purchased an 03 Pontiac Bonneville which has 35,000 miles. I smelled antifreeze and started looking around. The lower intake manifold was leaking coolant to the outside of the engine. I was so mad since I had the car for only about 6 months. A car with 35,000 miles should not have to go in for about $1000 worth of repairs to the engine. GM and Dex-Cool states that the coolant is good for up to 100,000 miles. I'm barely 1/3 of the way there. I should have drained the coolant the day I bought it and put the regular green coolant in. My other GM cars have been drained and replaced with regular green antifreeze. I'll never put this stuff in my vehicles again.

Physical damage to the metal parts of the car's engine, and the headache of getting the vehicles fixed.

Carole of Denton TX (12/28/07)
I have a 2003 Chevy Malibu that has almost 60,000 miles on it. I am having to have the manifold and intake gasket fixed and there is oil leaking into the coolant. My extended warranty company will not cover the Fluid Flush saying they do not know how oil gets into the collant. After reading other complaints I see that this may be a Dexcool issue. Now that I know this- I think back to my Pontiac Grand Am that I sold to my brother. It had to have a new water pump, radiator, and then the heater core failed as well. All could be related to Dexcool.

Michael of Helena MT (12/27/07)
ive owned my 2002 chevy venture for about 4 months now it has roughly 112,000 miles on it, i understand this is a lot of miles, but i've owned 3 other GM vehicles and never had a major problem with them, but anyways, 1 month after purchasing the vehicle the AC condenser blew a hole in it and i had to fork out 2,000 for that, and right now im in the middle of a new blown head gasket that formed the day i got a coolant flush from jiffy lube, i took it back to jiffy lube before i knew about the blown head gasket to see if it might have had a clog since it was overheating and wasn't blowing any warm air. Drove it across the street to a mechanic then they told me it was a blown head gasket, ive been hearing A LOT of these same problems happening and also some stuff about class action lawsuits... im wondering if the dexcool (which is the worst fluid ever designed) isn't deteriorating the headgaskets causing them to blow so easily... any information or remarks would be appreciated

Thomas of Kaukauna WI (12/12/07)
We experienced a loss of heat in our 1996 Lumina. I noticed a lot of pasty gunk around the radiator cap. I brought car to our mechanic. He informed us of the Dex-Cool issues and said our lines were very corrated and our water pump needed replacing because of the build-up. He cleaned the lines and installed a new water pump with a cost to us of $215.25.

Bob of Jenison MI (12/10/07)
i have a 1999 gmc yukon bought brand new,have already replaced water pump and intake gasket, now am losing coolant and overheating not leaking on the ground,probably a head gasket,after reading all the problems on this website i am inclined to believe it is a problem with general motors and the dex- cool coolant.

Carla of Palatine IL (12/07/07)
I purchased a new 2000 Chevy Monte Carlo with approximately 325 miles. In January, 2005, I noticed some antifreeze dripping in in the cabin on the passenger side. When I took the car to a local mechanic, I was informed I needed a new heater core. This was replaced and new antifreeze was added per GM guidelines. February, 2007, I had to have the radiator flushed again due to a dark sludge in the radiator that was mistaken for oil. The same mechanic that replaced my heater core also informed me that I had a head gasket leak and the oil was seeping into the radiator. When I took the car for a second opinion, it was discovered that this appearance is the result of Dexcool breaking down in the vehicle under normal use. January 2007, I had to have the radiator replaced because all gaskets were leaking and the car would not hold the antifreeze. This radiator replacement is only good for 40,000 miles.

Gary of Grass Valley CA (12/05/07)
As with many others I read about, Dexcool seems to be a problem. About a year ago the local dealer told me that the back of the intake manifold is leaking radiator fluid but not to be concerned unless/until the water gets in the crankcase. The repair is about $900.00. From All the complaints I read about, and over several years, many with leaking intake manifolds, General Motors should step up the the plate and do something about it.

Dan of Lone Jack MO (11/26/07)
Wife's 2001 Impala LS started having mechanical difficulty (accelerater pedal has to be tapped loose in the mornings) a couple of years ago. Took car to local Chevy dealership, but they said they didn't know what the problem was. Then took the car to our local Firestone and they knew exactly what the problem was - the coolant DexCool.

Joe of Rockton IL (11/26/07)
Intake Manifold Gasket needs to be replaced on 2003 Buick Rendezvous at 85K miles, appears GM DEXCOOL culprit. Coolant was warranty for 100K miles. Car is out of warranty. So I'm stuck with cost.

Melodie of Parma OH (11/24/07)
I spent $906.00 on Feb 6, 2006 for the intake set at Rad Air in Garfield Hts., Ohio. Dexcool is involved here. I took my car in today, Nov 23, 2007 for a standard oil change and am told that the engine oil is starting to get contaminated with coolant/antifreeze which indicates that the lower intake mainfold gasket may be deteriorating and requires replacement. This is the same thing that occurred in 2006, and I understand there may be a class action lawsuit with GM about this very thing. I have all the receipts and paper work, and would like to be included, if possible. Thanks

Lee of Clinton TN (11/23/07)
I'm interested in a filing a class-action lawsuit against the makers of Dex Cool used by GM. On 8/14/07 I brought my car into my usual mechanic for a standard oil change, at which time, the owner of Auto Medic, Kim, informed me that I had transmission fluid mixed in with the coolant and that my cooler lines in my radiator had a leak. I had to get a new radiator and it cost me $703 including tax/labor. When I returned to pick up my car, I asked him if he used Dex Cool and he said yes, that's what the recommended coolant for GM cars is.

I mentioned that there have been a lot of problems with Dex Cool, eating right through radiators, gaskets, spark plugs, etc. and he agreed that he had seen alot of problems with the Dex Cool being used as a coolant. At that point, he mentioned to me that it would probably start eating away at my manifold gaskets eventually, but there's nothing I can do about it as long as I keep using the Dex Cool.

Fast forward to Nov. 15th, my coolant light kept coming on, but at the time, I thought it was my battery logo. I continued to drive to work that week and Thanksgiving week until Wed. the 21st I made an appt. with Fox Chevrolet for Friday the 23rd of Nov. (today)(Auto Medic was closed) I initially thought my alternator was going bad again.....I just had it replaced 1/2/06. Today, (Nov. 23rd) when I brought it in, upon further inspection, the mechanic advised me that it was actually the coolant light coming on and that the intake manifold gaskets were leaking coolant. He brought me over to take a look under the hood and sure enough, coolant had leaked all over my engine.

I believe the Dex Cool was a direct cause of the leak. I've done alot of research on the product and I also had my mechanic at Auto Medic say the same thing. When I returned home today, I called Fox Chevrolet and advised the Service Mgr. (Terry Kennedy) that I DID NOT want Dex Cool put back into my car. I asked him to replace it with another coolant. He said it wouldn't be a problem.

I believe GM is negligent in not only still marketing the product Dex Cool, but they advise all service mechanics to use this product, and they specifically tell them Do not use a replacement coolant. Today's estimate is $772.00. My car is a 2002 Chevy Malibu LS. I purchased it in 2003 and it had 19,000 miles on it. I did all my homework prior to purchasing it. I paid CarFax a fee to find out if it was a rental (it was not) or if it had been previously wrecked (it hadn't) and also to find out if the mileage had been tampered with (it hadn't). These problems should not be happening to a 5-yr. old car. It only has 38,000 miles on it.

David of Lathrop MO (11/23/07)
My wife was complaining about smelling antifreeze while she was driving. I popped open the hood and did see some antifreeze on the side of the engine. I had it washed off and drove it to the garage, to have the oiled changed. The mechanic at the garage notice the antifreeze once again and told me of a similar problem they had with their son's car. I took it to a garage here in town, I bought the car as used, so I had no warranty. Sam's Garage, made a phone call to a GM employee, who said, unofficially, that they were having problems with the Dex-cool.

Taina of Lilburn GA (11/21/07)
I have a '96 Pontiac Sunfire SE. have had it for about 4 years now. I've always had issues with the coolant (ac not working, heat not working, overheating). As of late, it's been acting pretty strange. Last night on my way home from work, the temperature went from being pretty normal to going all the way in the red. I was about five minutes from my house, so kept driving. It cooled down a bit, but not considerably. This morning, I checked my fluids and sure enough my coolant level was almost completely dry and I noticed wet spots on the pavement under that side of my car. As I was getting ready to head back indoors, I noticed for the first time a little sticker telling me to use only Dex-Cool coolant. When I got to my computer, I
