Dex-Cool • Dex-Cool Class Action Deadline Nears • California Court to Rule on Dex-Cool Settlement • GM Owners Still Steaming Over Dex-Cool • Consumer Complaints

Ken of Vista, CA August 26, 2009

We have a 2000 Chevrolet Malibu with the 3.1L V6 engine. It has 48,000 miles on it and we have had cooling trouble with it for years. The antifreeze turns brown and gunky and we have leaks. We have flushed it multiple times and had to replace some seals, but it still leaks and overheats sometimes.

We were getting it serviced today and was told that there was some problems with the Dexcool coolant that these engines used and there was a lawsuit that would reimburse us for expenditures caused by this. I don't really need to be reimbursed from past problems, but I would like the problem fixed. What can I do to get it fixed without costing us a small fortune?

I have a 1999 Chevy Malibu only about 19,000 miles and it was taken very good care. I was told 8/18/09 I have intake oil/coolant leak. Will cost about 1,000.00. What can I do? I haven`t decided yet to take care of this as of 8/20/09. Of course my warranty has run out. If I don`t take of this my engine could be ruined he said. I have records of oil changes and etc. I assume it has Dex cool antifreeze.

I have a 2002 Pontiac Gran Prix which started over heating. I was told by my mechanic that Dex Cool was clogging the radiator and heater core and they needed replaced. He also noticed a small leak starting at the intake manifold. How can I file a claim for repairs?

My Chevy Malibu just now has a lower intake leak and someone suggested Dex Cool being the problem so I have been reading about it and found all the class action suit info. However, since that has been settled I don't know what I get to do about my problem now since it is beyond the deadline of the suit that was filed. Do I have any recourse?

I own a 1999 Oldsmobile Intrigue GL 4-door sedan which this GM dealership's service department estimates will cost over 1,000 to replace the intake manifold gasket which has been eroded by GM's DEX-COOL coolant. There is no guarantee that this problem would not reoccur after the repairs! I asked if there were any alternatives, and whether or not I could swap out the radiator and entire cooling system and use something else. They could not recommend using something else and said the sludge that had accumulated from the DexCool was a permanent, irreparable problem. This is the 2nd Oldsmobile I have owned which has experienced this problem.

I have a Chevy impala, 2006 with 72,000 miles. In the past few days I've had a couple issues with some overheating of the engine and leaking of fluid in the garage. Today the water pump failed. Luckily, I was within 2 miles of my service garage, Firestone at 120th Ave and Colorado Blvd in Thornton. I allowed the engine to cool and proceeded to Firestone. They immediately diagnosed the problem, replacing the water pump.

When I was checking out I commented that my car was awfully new to be having this type of issue. In the 40 years of owning cars, this has never been a problem under 100 or 120,000 miles as I recall. He commented that they've replaced at least 3 water pumps in Impala's in the past 3-4 months. That comment prompted me to look into what other issues I might be up against in what I consider to be a well made car and I love. I drive too much and like to be proactive in preventing problems. This is when I found others had issues where they thought the coolant was a issue.

I am completing this form in hopes of finding a recall for the Dexcool coolent used in my 2004 Buick Lasabre. It has caused to replace my intake gaskets, as well as the manafold gasket. Apparently, the Dexcool eats away at such gaskets causing leaks. Therefore requiring costly replacments. I find now that my water pump needs to be replaced due to the same Dexcool problem.

I purchased my vehicle through a dealership, used about 1 year ago. It only had 40K miles and I have had the Dexcool removed since. I am looking for a recall of such usage in order to reimburse the expenses incurred and will incurre very soon. Economically, I can't afford to pay for repairs caused by a defective product.

I own 2005 Chevy Avalanche. I had to change the water pump and thermostat last year since it developed a severe leak spontaneously. I always used Dex Cool anti-freeze per GM recommendation. However I have recently read many articles about Dex Cool creating problems for other GM owners similar to my experience. If you know about this issue please advise.

My engine in my 2004 Monte Carlo overheated. It started when the dealership told me that my waterpump was leaking and this was around 65,000 miles. And so in june of this yr my car overheated so I have the waterpump replaced.It still didn't go way.I decided to go to the dealership because I was told air was getting in the system. So the people at the dealership tell me that they can't find where any air is coming from,I wasn't charged,then my car overheated again I took it back to them and still no luck.So we changed the thermostat. The car still overheated and my old thermostat still works.

So I went to my old Mecanic and he told me that the dex cool has eaten the gasket around the manifold and thats where the air is coming from.So I get on the web and pull up articles about dex cool. And sure enough that is the problem. My transmission may be affect by this and I bought the car brand new five yrs ago and now they are telling me that I need a new transmission.
