Anybody else's serpentine belt squeeling when the AC compressor clutch engages? Took a trip this week and there was alot of rain on the way over so I thought maybe the belt and pulleys were just wet but once things dried up it still squeeled. I tried it again today while in park but it didn't squeel at all. Sound like I need to replace the belt or is it something more serious?

 

How many miles do you have, sometimes the belts will like to squel if you degrease your motor a lot. I still clean mine that way, but now I do not spray the belt at all. You can use some squeel away from any auto shop, but this is just a temperary fix. If you dried out your belt, or if you have over 30,000 miles of hard driving on the motor the belt can start to go bad also.

One last thing, is that I have heard several times that the stock belt tensioners go out real easy on our trucks.
