Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety.

2002 Chevrolet Blazer Owner Comments

problem #2

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.
