Q: Car squeaking around belt area

asked by on

My car is making a squeaking noise around the belt area.

A: The symptoms you describe for your GMC Yuko...

The symptoms you describe for your GMC Yukon lead me to believe that we are dealing with a worn out serpentine belt. As the belt ages, the rubber starts to deteriorate and stretch. This causes the belt to rub material off on to the pulleys and produce a squeaking noise. To be 100% certain, however, it may be in your best interest to enlist the assistance of a certified mechanic to properly diagnose the squeaking noise. They will be able to remove and inspect the serpentine belt, as well as all of the pulleys, to determine what needs to be replaced and get your GMC back on the road.
