I have tried just about everything to eliminate the screeching sound coming from the water pump area. It went away for awhile when I installed a new Gates belt, but then returned. I pulled the water pump pulley off and wire brushed all the old rust and grime off the pulley thinking this would surely solve the problem. No dice. I have tried loosening the belt, tightening the belt, making sure the belt is lined up properly (this is a alternator conversion car). Nothing works. If I take the belt off and start the engine it purrs like a kitten. So....I know it is either the belt itself or the water pump. However, since I did get it to quiet down for a time by installing a new belt, this would seem to suggest that it is not the water pump? Then again, if I tighten the belt to it's normal tension the sound gets a lot louder. (pump bearings??) I am about to install a new 6 blade water pump from Moss. If the noise still persists after that then I am considering installing this new (3/8" belt & pulley conversion kit) from Moss. This will give me new pulleys all around and the proper belt. My question is: has anyone in here done this? Supposedly according to Moss it helps with engine vibration etc; and is a good upgrade. It isn't cheap and I don't want to waste my money, but I am really getting frustrated with this noisy belt issue. Someone out there on some forum warned against eliminating the stock engine fan (removing the engine fan and installing an electric fan is part of the deal with this) because it would throw the balance off and could cause crank shaft damage??? Anyway, I will replace the water pump and see if that does it. Then...........????? :sorrow:
