Question type: Maintenance & Repair

Every time I start the car it
squeaks sounding like a belt? I
did have the serpentine belt
replaced 1 yr ago and someone
told me belt might be wrong? It's
a loud squeaking that lasts a few

1 Answer


It might be a pulley - there is an idler and tensioner that may make noise when they go bad. Try loosening the belt (requires a socket on the tensioner, google for specifics), then spinning each pulley by hand. Idler, tensioner, PS pump, alternator, and AC. If one feels rough then it likely has bad bearings.
