[QUOTE="Flyer58, post: 437367, member: 18629"] OK I made a little progress, possibly. I tried belt dressing and while it helped with the start up squeal it did nothing after tightening the belt. I also tried putting a load on the alternator by turning on all the lights and fan - no change. The loaded up the PS pump by turning the steering wheel to the stops and again no change. Next step was to try and isolate each accessory. First I simply removed the idler pully to eliminate it and no change. Here's where it gets stupid, don't try this at home, entertainment purposes only, learn from what I did. No animals were hurt during this test. I tried the tie wrap trick using some 2ft plastic tie wraps a neighbor gave me years ago and have no other use for. I ran each pully individually, water pump, alternator, and power steering. Low and behold the power steering pump squealed. Like I said the pump works well, functions properly without any internal noises you normally hear when they go bad. Just belt noise. I'll try the Dorman steel pully next. For LOL's and yes I know the water pump is turning the wrong way but only for a few seconds. Cheers. [ATTACH=full]120985[/ATTACH] [/QUOTE]
