may have some twist in the mounting or a bad tensioner......Had an old truck that took a shot in the front end and the bracket was bent, but didn't know it......Bought an unneeded alternator, and still squealed. Could very well be something else but you can check to see if the mount is twisted with a yard stick.....

a small squirt of water on the inside of the pulley will tell you if it's a bad bearing.. noise goes away then that's it. Since it's water the noise will come back but it's less messy then belt dressing which is pretty much a waste anyway. Find the pulley and replace part.. If it's a new belt then it's likely a pulley which is throwing the belt out of align.. Here's to hoping it's the idler, since that's the easiest to fix.
