1998 Chevrolet Blazer: engine failure

Filed Sep 3, 2005 · Engine · 67,000 miles · CO

I owned a 1996 chevy blazer. The seal on the engine went at 70k miles. Had to replace engine. I now own a 1998 chevy blazer, replaced the seal in dec '04 and the engine blew at 67k miles. Had to replace (rebuild) this engine. I have service records for both vehicles. No reason to have two engines go. I wrote gm and got no answer.

Chevrolet dexcool coolant not good for 100,000 miles as advertised. Two previous radiator flushes, one was one month prior to engine failure. Told due to overheat despite no signs of overheat. Chevy dealer says no signs of cooling system having ever been flushed despite another chevy dealer flushing system approximately 1000 miles previously. Chevy and texaco state vehicle must be driven for extended periods (20,000 miles) with low coolant levels to start corrosion clogging up cooling system. Not so in this case. System had been flushed and filled by chevy dealer on 6-11-2. Aproximately 1000 miles later, on 7-8-2, chevy dealer notes buildup in cooling system again. Coolant system had not been low, and had not been extended period. Remanufactured engine and new radiator being installed, chevy denies any knowledge of problems of this sort with dexcool.

Dex-cool apparently changes state from a semi clear oragnge liquid to a muddy murky corrosive material. Chevrolet has issued a service bulletin 99-06-02-012b...coolant is suppose to last 150,000 miles it was flushed 30 days ago and it has again changed to the muddy corrosive liquid...it also has eaten through my radiator core. Why if they are aware of this problem as indicated by their issuance of a service bulletin why do they not recall and repair or replace engines and other components damaged by this corrosion.

Vehicle burned over 9 qts of oil in 3-4 months. First noticed 12/98, dealer began checking and testing. Finally, in april - may 1999, it was determined that vehicle was burning about 1 qt every 300-400 miles. They finally agreed to replace entire engine because they could not locate source of problem. The night before carrying it for service, vehicle lost transmission power. The dealer had to tow the vehicle in the next day. At this time, they not only replaced the engine, but also the entire drive train/transmission system. They still have no idea what caused the failures on such a new vehicle. I tried to get a replacement vehicle since the first failure was around 5,000 miles, but the gm representative refused and only offered to replace the engine and transmission. I don't think I'll ever fully trust my vehicle now, but can't afford to trade at the moment.
