Dexcool has gotten a bad rap lately in a lot of places...I dunno I have it in three of my four cars, but two of them are a 2001 and 2002. My 1996 Corvette has Dexcool in it an it was putting a little sludge into the overflow canister. That is usually a good sign that the corrosion inhibitor package in the coolant is done. it also happened right at 5.5 years of coolant age. I simply flushed the cooling system and refilled with new Dexcool. Also washed out the overflow canister. This was last spring and I have had no more sludge coming up in the overflow. I also chaned the radiator at that time cause mine was beginning to leak at the tank seals..the entire system as far as I could see was spotlessly clean.
