Why my pulleys are squealing?eduardo - 2005 Subaru Impreza - Engine - 7/20/2010noise comes from alternator and or water pump maybe the pulleys
-
7/20/2010 Sublym1That squealing sound is possibly your alternator or a/c belt. Is it a constant squeal or intermittent? Does it only happen while you're accelerating or while the engine is under heavy load? Check the belts to see if they are too loose or for any cracks or glazing.

7/20/2010 Sublym1That ticking sound could be your spark plug wires. When the wires get old and brittle, the spark finds it's way through any cracks in the wire and connects to the nearest ground. That would cause loss of power since you're not getting full spark to the combustion chamber. Try replacing the wires and take it from there.
