2002 Chevrolet Trailblazer EXT Engine cooling Problems

“Our 2002 Chevrolet trailblazer loses power and the trouble lights flash including the service light and reduced power light come on. I have changed the 02 sensor, flushed the transmission, replaced spark plugs and had the emission system checked all to no avail. Our mechanic cannot isolate the problem and all things we have tried has failed. We have reset the computer several times to no avail. This is a problem and safety issue. We have had no help from GM.”

“Have been having major trouble with the front end. Had it checked multiple times at the dealer and at a local mechanics shop and the ball joints and bushings had to be replaced. Even the the warranty was finished, the dealer did not charge me for this, but unfortunately I thought that this would take care of the noise on the front end, but it is still there!! Also yesterday, april 24, 2007, I had to have the fan clutch replaced. This vehicle only has 35,000 miles. …”

“I backed of the garage and heard a loud noise. As I pulled forward the truck moved very slowly for how far the gas pedal was pushed.

“I have a 2002 trailblazer with about 50,200 miles and the other day it began to make a high pitched sound, almost like a plane landing. When I took it to the dealer, he said it's the fan clutch and it's going to cost $711 to fix. When I asked if this is normal wear & tear, I did not get a proper answer. The response was that this happens a lot on the chevy & GM vehicles. When I called chevy corporation, I was given a claim# & told that they will have to investigate this problem & then they will call me back in about 3 days to advise if they will help with the costs of the repair. …”
