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.

My dex coolant isn't to be replaced yet but it is already steaming and overheating.

It is destroying my engine.

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?

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.
