Just bought my 2003 chevy impala from a private dealer, it only has 22,000 miles on it but was a salvaged title. Three days after purchasing the vehicle I noticed a loud screechy/grinding noise coming from under the hood. I've only noticed it do it a few times since yesterday, not at all times but it's really loud and annoying so we checked under the hood and it seems to be coming from the belt. I'm going to get it looked at on Monday to see what for sure needs to be replaced.

Tensioner pulley froze up and belt broke. Replaced TENSIONER PULLEY and serpentine belt...shop cost was $156.12. Thought it was a little high but the weather was cold (15 degrees) and I didn't want to be outside working on it. You should be able to buy a replacement pulley for $35/45 and time to change requires about 1/2 to 3/4 hour. If weather was warmer I could have saved $100 plus by doing it my self.

same thing happened to me, the pulley assembly became loose and as I was driving the engine would shut off from loss of power at stop lights. had it replaced today and it runs new.. the spring wore out in the old assembly.

Serpentine belt snapped, after about 2 months of an on-again/off-again squeal. Shop said it was because the tensioner pulley had seized, and had to replace the pulley and the belt.
pulley actually jumped out of socket too far and off belt so I had no power steering at all
I have changed my serpentine belt 2 times the first at 35000 miles and again at 70M + miles but never the pulley
