I have a 2000 Jeep Grand Cherokee, 4.0 liter, 2 wheel drive, 102,000 miles.
Replaced waterpump last Feb. My car is now making loud chirping and knocking noises, so took my car to the same garage. They said the BELT TENSIONER is worn out which made the WATER PUMP fail. Can this happen or are they trying to cover up a mistake they made last Feb?
* Another note, last June my SERPENTINE BELT broke while on a road trip and I had it replaced. Can this have anything to do with the BELT TENSIONER and WATER PUMP failing?
