Have you tried replacing the tensioner. The spring in the tensioner is problably worn.

Take the smooth sided pullies and take some fine scotch brite and scuff them some. I did this with mine and it stopped the squeeking sound. Like if the water pump pully isnt a ribbed pully, but a smooth pully. Just take it and scuff it up some.


How much can you move the belt up and down? You sure you got the tightest fitting belt for your set up?
