Gawd Awful Screech
 

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.

I personally think that if your pump i making that noise just spinning it by hand, something is really wrong with it. Its probably about to fail. Sounds like the bearings are worn out. Is it weeping from the hole on the bottom of it? If there is any moisture there or drip stains, its seen better days. Do your self a favor and don't buy a cheap piece of junk replacement.(thats cheap insurance advice) Winters coming so make sure your antifreeze is up to snuff also. Hope this helps.:metal:

That was my guess too, bearings. Pump performs fine, engine runs cool, no leakage, no seepage or anything. But I agree, failure is not an option. i want to keep the factory cast numbers so will rebuild if I can.

check the forum search to see if anybody here has done it before. Im sure somebody has.
