Squealing noise from the serpentine belt?
The belt or maybe it's one of the pullies that's
making a loud, continuous squealing noise. How
do I go about find the source of the squealing?
Take the belt off and inspect the idler pulleys, the belt tensioner, and AC bearing.
See if they spin without making noise, check for wobble in the pulley.
also, a worn belt itself can squeal.
