I have a squealing noise around my serpentine belt, my friend told me it was bearings are gone in one of the pulleys, how can I figure out which pulley it is?
There is only one pulley, here is a photo of what it looks like...
There is the alternator, and water pump and whatever else that belt goes around, how do I know which one is making the noise, to my war sounds like the alternator but how do I find out for sure without taking to a mechanic
To see if it's this Pulley, SPRAY WD40 on the back side of the pulley, not the belt. if the noise stops then its this pulley...
Take the belt off and turn the pulleys by hand. If one doesn't turn very easily replace it.
