The serpentine belt tensioner pulley may wear out. Our technicians tell us that in order to get a new pulley from General Motors you must purchase a complete belt tensioner assembly.

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.
