Varies with revs. Can be heard from drivers seat. Does not sound like any pulleys or anything like that but I know how sounds travel. '95 Aero.
Got around to doing this just now. Removed belt and noise was gone. Since i initially thought it was the alternator, I checked that first. It was good. Next the power steering pump. There it was. Noisy while spinning. Gotta replace the pump. Going on vacation in the NH White Mountains in 10 days.Take the belt off and see if It is still there, also turn the pulleys by and to try and locate it
