I have a '97 SE with a 3800. The serpentine belt will NOT stop squeaking! It doesn't squak at idle, only when the RPMs rise.

The belt is not worn or cracked. I have used STP belt dressing, which makes it go away momentarily, but it returns after a few minutes.

Do I have a pulley out of allignment? Could it be a cheap or bad belt? Like I said, when I spray the belt dressing on it, the squealling goes away for a few minutes, but soon returns.

I am going to replace the belt, and see if that helps, but I can't replace it until this weekend, because I will be working 14 hour shifts all week, and I won't have the time. I was just curious to see if someone could enlighten me as to what might be going on.

Thanks in advance!
