The problem described below has occurred on 3 previous occasions.(1) events leading up to the failure - "dex cool" coolant leak from intake manifold gasket. 2) failure and its consequences - loss of coolant leading to engine overheating or failure. (3) what was done to correct the failure; I.e, parts repaired or replaced (and if old part is available) - GM started using "dex-cool" extended life coolant in 1996 it didn't test the long term affects on it's existing gasket technology. One article I read stated "it appears that on some engines, the use of conventional plastic-and-rubber gaskets in combination with more aggressive oat (organic acid technology) engine coolants has caused a significant number of sealing related issues for consumers and automotive service providers", said fel-pro chief engineer jerry rosenquist -- per P://www.theautochannel.com/news/2004/10/14/252583.html. dex-cool is an oat coolant manufactured by texaco for GM. Over the past few days I've read many complaints about GM intake gasket leaks and it seems more likely that the coolant, rather than the gasket itself, is causing the problem.

I had to replace the lower intake manifold gasket due to antifreeze leak, and now the head gasket is leaking antifreeze.

At 70208 miles dealer replaced water pump at my cost, again at 91000 miles dealer replaced water pump. After complaining to GM the dealer agreed to warranty parts and labor. 2 water pumps in 91000 miles! #2 brakes at 48911 dealer replaced front disc and warped rotors. Again at 91000 miles dealer says rotors are warped again and replaced, both times at cost. 2 sets of rotors in 91000 miles! neither time were the rotors visually damaged or worn from disc pads. **dimsii IVOQ entry posted after 12/12/02 cut-over to artemis*734293
