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.

    Horrible sound, A/C Tensioner Pulley needs to be replaced. A/C still works, as does heater. But it is about to go out (causes a grinding sound in front left engine area, that changes pitch when you hit A/C switch or heater switch)

    Belt broke on the car. Replaced the belt. High pitched squeal and the new belt was trashed. Then replaced the tensioner and belt, the car ran as good as new.

    This problem occurred after a catalytic converter replacement. The first shop said that this would run me $385 to replace the Drivebelt tensioner as well. Luckily, I had another shop replace the pulley for $90 and it did the trick.
