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.

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!

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.

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

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,
