I've got some racket and I can't pinpoint exactly where it is. Sounds like something driven by the belt for sure. It's almost like a grinding sound at idle, kinda comes and goes. When driving, it adds a faint squeeling. It doesnt do it all the time, but as of today, it is doing it a lot worse. Any ideas? Thanks

 

You can use a long screw driver, and place the tip around each pulley with the handle pressed against your ear too pen point where the noise is coming from.. Power steering pumps usually whine,idler pulleys & alt, water pumps will grind
