Gawd Awful Screech

[geunther]

I have a high pitched squall which sounds like a slipping belt. I put new belts on, tightened em up as they are supposed to be, but it still screeched right after the engine being started, then it stopped. It would also do it running about 40mph and accelerating hard when the transmission downshifted. I finally removed the belts and the screech went away. I know I had them to the correct tightness.

When I spin the water bump by hand it groans and sounds like in injured goat. I am wondering if under a quick throttle pump the water pump would provide enough initial resistance to cause the belt to slip. I suppose the right thing to do is to rebuild the water pump.

Just wondering if anyone had experienced this and if replacing/rebuilding the water pump helped the belt noise.
