Serpentine belt tensioners are notoriously unreliable and can fail for no apparent reason. Also, the springs weaken if they get too hot.

Did the squealing problem start after you drove through a desert in summer, or after the engine overheated?

Cannot tightened. The tension is controlled by a tensioner.

My assumption is that the belt is squealing. Belt dressing may help.

Replacing belt is most effective, even if you just replaced it.

If a new belt does not stop noise (assuming noise is problem) most likely idler or tensioner bearing is bad and the idler or tensioner needs replacement.

You can troubleshoot by carefully spraying a small amount of WD40 on the bearing of each of the tensioner or idler. If noise stops there is your problem. DO NOT get WD 40 on belt. Be careful not to get your fingers in running belt.

The belt is self adjusted by a spring loaded automatic belt tensioner, if the belt is noisy or seems loose either the belt size is wrong (if it was replaced recently) or the tensioner is defective or one of the belt idler pulleys is defective.

Serpentine belt tension release


on the idler there is either a bolt or a square hole. if it has the square hole it is for a 3/8 drive breaker bar if it just has the bolt on it find a wrench that fits turn either of them right as if you were tightening them this will release your tension.
