While driving, the temperature gauge spiked and the check gauges light came on. One of the bolts that holds the thermostat housing to the manifold had sheared off due to bolt brittleness. This caused a serve loss of coolant and the remainder of the thermostat housing bolts to become broken off in the intake manifold. Resulting in a repair of at least $1,000 due to having to replace the manifold. The shop was only able to extract one broken bolt from the manifold. This vehicle is a lemon. We have replaced everything on it, some things more than once including the engine, transmission, and multiple radiators all under 75,000 miles. We have replaced the gas cap to the radiator cap and even the windshield too. This will be the second intake manifold as the engine had to be replaced 5 years ago due to failure of the head gasket due to a faulty gm design on engines made between 2000 and 2004 and dexicool coolant issues.

The heater and defroster failed to generate heat. No events leading up to failure. This fall when we needed the heat and window defroster just luke warm air was coming out. The intake hose to the heater was hot the out take hose was cold. This failure causes a major safety issue because the front window will not un-fog and the ice and snow will not melt off the front window. The driver can not see out of the front window. There is no warning to this problem. Research this problem on the web and there are numerous other people and vehicles with the same problem. It appears to be caused dex-cool coolant. This web site http://www.geocities.com/b_gillie/dexcool_problems.html has more information on this problem.

Immediately following purchase of a 2002 chevrolet blazer in august 2002, I noticed a loud roaring noise coming from under the hood which occured mostly upon startup when engine was cold and put into drive gear. This noise was also intermittently noticed after coming to a stop and then accelerating. By the time I drove it back to the dealership, it was not doing it. Since purchase, 2 replacement batteries have been installed. Service dept at dealership said alternator was draining the battery and replaced the alternator. Car is still doing this but dealer is unable to duplicate and saying loud roar is most likely normal. Now several acquaintances have said they had the exact same problem with their blazers even though they were a different year model. Once the warranty runs out, this problem could add up to quite an expense.
