I'm at my wits end...I have a chirping sound that corresponds to engine rpm's that I've tried everything to remedy. I have replaced the serpentine belt, belt tensioner assembly, water pump, have checked the alternator, and the a/c pump, and power steering pump. None of the components appear to be the culprit. If I spray water on the belt the sound subsides, so it's obviously belt noise, but I cannot find the source no matter how hard I try! Any Ideas/Suggestions gang??
