 Due to intake manifold gasket leak (this is the fourth time for this problem on this vehicle) i had to stop to add coolant in order to safely drive the vehicle. had i not noticed the problem this potentially could have left me stranded on the side of the highway. after getting to a safe location i had the vehicle towed to a dealer for repair. also, as i stated above this is my fourth time dealing with this issue; in addition, i know of personally 3 other vehicles with the same engine that have had the same problem and they too have changed the intake gasket several times.*ak

 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.*ak

 When i purchased this car, it was the car of my dreams. i had it for less than 2 weeks, when i noticed sludge in the oil and around the cap. i was told that it was condensation! it wasn't. it was the intake manifold gasket. when i first complained to sunshine ford, where i bought the car, it was still under warranty. when it finally blew, thank god 10 feet from my driveway, it was 300 miles over the warranty. i had nothing but problems trying to get them to fix it. they diagnosed it wrong to begin with! it ended up costing me around 250.00. two weeks after i got the car back i was doing 65 on the highway, when something big dropped out from under my car. it was the computer and the front guard! they charged me for that too. now, i started up the car the other day and heard a muffler noise in the front down in the engine. my drivers side manifold is cracked all the way around! needless to say, this is another $6-700.00 i have to put in this car! also, my steering column, turn signals shorted out, were replaced, but i still get surging in my lights. i am not at all happy with this car, or chevy. oh! and let's not forget the snapped frame on the front driver seat!*ak
