2002 Chevy Trailblazer 6 cyl Two Wheel Drive Automatic 180000 miles
When I start my vehicle it idles rough, once I get going in drive it is a very rough ride and I can hear chirping noises coming from the engine. It is the loudest when I go from 1st to 2nd and then from 2nd to 3rd is not as loud, but is continuous while I drive. I opened up the hood and looked at the fan and it was shaking and I could see the belt moving back and forth. My question is How do I tighten the fan assembly so that it does not shake and how do I stop the belt from sliding back and forth, it looks like it's going to slip off. I was told it could be the water pump bearing going out, but I'm not sure that is the problem. The problem has gotten worse in the last 3 days, I'm afraid to drive it, for fear the belt will slip off and I'll be stuck somewhere.
