I just replaced my power steering pump thinking it was whining but I'm still getting the same....frustrating to say the least. The whine (loud) starts immediately when the engine starts and gets louder as the engine revs. I can hear it over my freak'n exhaust!
It actually sounds like it's coming from the timing or tensioner. Any help would be appreciated. I've got to get rid of this.
Actually I think it's the AC. The pulley below the tensioner to the left.

Thanks. I wish it was the power steering pump but the new one is quiet as a mouse. It sounds like it is coming from the a/c pulley near the tensioner. The whine was gradual at first now it's just all out.
you can pickup a stethescope from an auto parts store and place it on all of the pulleys and see if its an idler pulley or a tensioner or anywhere, it might give you a better idea of where the noise is coming from. is it a whine or is it like a belt squeal? does it only whine at idle or all the time?
Yeah it's all the time and it's a loud whine. The whine goes up and down as the engines idle changes. I'm almost positive it's coming from the ac clutch/pulley but I'm taking in to get checked out tomorrow.
I have a 1998 GT and am experiancing the same thing after replacing my serpentine belt because the old one was frayed. The original belt did not make noise.
I replaced both pulleys and the water pump with no change in the noise. I spent many hours reviewing postings on this sight and on others for the same problem. No one would definitively say what caused or fixed the noise.
I believe it is caused by misalignment of the pulleys or the amount of bending (backwards the belt has to do over the water pump). The noise was bad on my car yesterday, I went home and sprayed silicone spray on the flat side of the belt only. The noise immediatly stopped and would not return even when revved.
My path forward is to
1. Continue to drive until the belt "breaks in" or
2. Replace the belt with the Goodyear Gaterback. The reason I think this would work is because the Gates belt I bought at NAPA has continuous ribs on the inside of the belt. The Goodyear belt breaks up the ribs so it is easier to bend the belt backwards.
Has anyone fixed this problem by using the Goodyear belt?
