A: I've had bad belts and cracked pulleys make noise, and sometimes the pulleys touch between top (waterpump) and bottom (crank) due to sloppy waterpump bearings. I had to loosen the bolts on the used waterpump I installed on my J4000 and lift the pump up slightly to get the pulleys to stop clacking together.

At certain rpm's as I accelerate I hear a rattling coming from under the hood. It goes away if i let up0 on the gas or if I go above the speed I hear the rattle noise. I am going to take the belt off the pump temporarily to see if that is the cuplrit. If it is, where can I get another pump or get this one rebuilt? The pump works great. It is an "add-on" by the previous owner but is an "AMC Authorized" pump. Not a "Kluged" aftermarket unit. Jay Lake Placid, FL.
