It's equipped with the scandalous dex-cool antifreeze. My engine light came on the other day and I had a diagnostics ran through my On Star and they said it had something to do with my cooling system. I found out the part that needs to be replaced. Yesterday I recieved a class action law suit from the State of Missouri that states dex-cool that is equipped in all 96 - to current models are causing major problems. Symptoms including a sludge like forming on the radiator cap. Which has happened to mine. It also states that it can also cause many major problems like corroding the engine and eating away at the gaskets. Has anyone else had a problem with thier GM model and or with this sludge like stuff? It's totally wierd. I think I'm selling mine asap.

Mine did the same thing (engine light) but I didn't have any of the problems with the dex-cool you described. It could be due to different climates or something like that. My owners manual says it takes dex-cool only but I put a little regular anti-freeze in it by mistake but I took a siphon pump and pumped most of it back out before it was cranked and replaced with dex-cool and it has been fine.

im kinda glad to hear someones finally making a big beef over dex-cool. yes, the stuff is corroding crap, im not sure its a reason to get rid of the car though. the sludge is also often caused by stop leak bieng installed, as per factory gm repair procedures on certain jobs. most common problem with the dex-cool/ gasket thing is intake manifold gaskets. expect to do them every 60 thousand miles or so. appx cost- 700-1000 bucks depending on where you live.

I haven't had any experience with the GMs, but I have seen the dexcool equivalant in Chryslers. I have noticed that the long life coolant evaporates at a rather quick rate. I have also noticed that it crystallizes when exposed to air. In my mind, that can't possibly be good inside an engine or a radiator. I can't say that I have seen excessive corrosion, but I have seen the crystal flakes inside engines that I have torn down. I prefer the good ol' green stuff, and I am sure the dexcool and other long life coolants will run into more problems down the road.
