Now its the waterpump!!!

It seems like there's always something to do on the truck. I think the waterpump is going. There is a horrible squealing sound from under the hood. Sounds like bearings. I know its not the power steering pump, or idler pulleys (I recently changed those). The belt is not slipping. So I've narrowed it down to the alternator or waterpump. The waterpump is factory (191,000 miles) so I'm sure that's it.
So another weekend of auto repair is upcoming!

Re: Now its the waterpump!!!

Usually waterpumps start leaking when they go bad.

A telltale sign an alternator is going bad is if the pitch changes with current demand. IE: turn all your lights and stereo on. Also, the voltage tends to fluctuate more as an alternator starts to die. Mine has been dying for a month and a half now.

Re: Now its the waterpump!!!

I always thought they leaked too. But the Haynes manual says differently. The alternator is putting out good juice, no matter what accessories I have turned on.
This all started when I put on a new belt that seemed a little too tight.

Get a Stewart waterpump

Stewart Water Pumps

I have one on my camaro and I know a lot of people who use them. They are hands down the best you can buy, but because they don't use suppliers like Summit and Jegs, they are very compitively priced. When I bought the one I have, I held it up next to a factory replacement and felt wiggled the shaft, the tolerances were extremely tight in the stewart.

It cost me about $90 shipped, but I know I've got a unit that will last forever!
