Alright, I am at my wit's end now. For about 10 minutes after I start my car, my belt squeals like mad! It also chips at high RPMs. I have replaced: the power steering pulley, Idler pulley, the entire tensioner, and the belt itself. I have checked every pulley and all of them sound fine on their own. What the heck am I missing? It's cold out. Put when I first got the car it was cold and it didn't squeal. The sound does go away after like 10 minutes... but god it is super loud.
