I recently replaced the serpentine belt and tensioner on a '99 Pontiac Montana. The belt had signs of wear and after replacing the belt the tensioner broke. I have had the new belt on for two weeks and it started squealing. The squeal would go away after running for a few minutes, but would come back after shutting the car off. I checked the belt and noticed that the belt material appears to be degrading. The back side of the belt feels gummy. I found the power steering resevoir to be empty. Is it possible for the power steering fluid to have caused the belt to deteriorate? I feel like The power steering pump needs replaced but I don't want to just throw parts at this.
