Over the last few days, it has developed a constant squeal from the engine. Cold or hot, idle or reved abit, the squeal is there. Reving makes it a more pronounced squeal. Sound eminates from the passenger side of the engine in the vicinity of the serpentine belt and alternator. With engine idling, I sprayed a small amount of "Belt Conditioner" on both sides of the belt but it did not help. I do not see metal shavings around the pulleys of the Alternator, idler, crank, etc that have pulleys driven by the serpentine.
My guess is a failing bearing in the Alternator or Water Pump but praying it is not the Crank. Was going to loosen serpentine and hand turn the Alternator, Idler, and Water Pump pulleys to isolate source but hey I'm just a backyard mechanic. Advice?
have the same problem?
