So now I have belt squeak that will not go away, after 3 belts. I just discovered that my idler pulley is making a bit of noise, and my water pump has VERY VERY little play in it, and is still damn near silent when I spin the pulley. I think I'm going to start by replacing the idler pulley and see if the squeak goes away. I don't think that it's the tensioner itself, because when I turn the A\C on and\or crank the steering wheel over all the way the squeak doesn't change. Anyone have any other input on the matter?
