I had my Water pump and Serpentine replaced in sept 2006. Last week there was a squealing noise under the hood that would occur between 2k-3krpm. Higher than that the noise disappears. I took it to the shop, they said the pulleys all look fine and replaced the belt again, but the noise still continues. What could be causing this to happen even after the belt was replaced? The tension on the belt is fine. Could this be the result of the excessive amount of Salt thrown down on the roads due to recent snow/ice? I don't want to spray any lube like WD-40 as I was told this would contribute to the degredation of the Serpentine Belt.
