Belt squeal with A/C off, gone when ON???
I have isolated the squeal under the hood when I start up and when the cab A/C is off. When I turn on the air conditioner it goes away. I changed out the belt tensioner and serpentine belt after 8 years and 50K of wear. It's 4 years later and 21K. When I turn on the A/C, I can see the belt tighten up just a little. Should I start by replacing the belt, then if that doesn't work, put back on the old tensioner. If that doesn't stop it then it's probably the A/C clutch.
Any thoughts????
