Any one have any ideas?? Is my waterpump toasted?? Thanks in advance!!!!   Peter Matusov (Pmatusov) Senior Member Username: Pmatusov Post Number: 634 Registered: 09-2002 Posted on Monday, April 07, 2003 - 04:13 pm:    Corey, does it sound a bit like cavitating power steering pump? peter   Paul T.

Replace the tensioner bearing and the serpentine belt-it might go away. The TSB says to do the above, but I've also been told that if the tensioner spring begins to get weak, it will make the same noise. Corey-I spent a small fortune replacing everything but my air conditioning compressor and it turned out to be the tensioner/belt. Of course, I didn't find the TSB until I had replaced the water pump, alternator and power steering pump!   Blake Monchilovich (Azblake) Member Username: Azblake Post Number: 43 Registered: 02-2003 Posted on Monday, April 07, 2003 - 05:57 pm:    stethoscope it   Jason T.

Does it make a kind of weird noise when you shut down the engine? If so the water pump may be the culprit.   Corey Shuman (One_bad_rover) Member Username: One_bad_rover Post Number: 93 Registered: 09-2002 Posted on Tuesday, April 08, 2003 - 10:58 am:    it does make the wierd noise on shut down. but there is a tensioner on Ebay to so maybe I will do both. Any better place than the dealer to get a waterpump? Local dealer wants $224 for the pump alone!!! Thanks for the advice too!!!!   Paul T.

You may not need to replace the entire tensioner. The bearing will only cost you $10 at the most, the belt a little more. It is much cheaper to replace the bearing and the belt than the water pump. Pulling the tensioner off and cleaning the mating surface may also help, unless the spring is becoming weak. I would not replace the water pump until I had exhausted the other avenues, but do as you wish.
