Remove The Altenator and where the top radiator hose is attached to the block take the two bolts out. The whole piece that the hose go's on is the thermostat auto zone is cheaper.

AnswerThe thermostat comes in a housing that bolts directly to the motor, and is located on the driver's side of the motor, about 1/2 way from the top, & towards the front of the engine. To remove/replace it you need a socket wrench & a 3 to 6 inch extension. You will have to remove the alternator and serpentine belt to get to it. This is where the thermostat is located on the trailblazer for years 2002 to 2004.
