I have a 99 corvette and its making a squealing sound coming from what sounds like the main drive pulley. I lubed the belt with STP belt dressing, but it continues to squeal. I replaced what I thought was the idler pulley, but that didn't work. Now someone told me that it may be the water pump. When engine is cold, the noise is very loud until the engine warms up, then the noise is still there, but not as loud. Does anyone know what might be causing this noise. I have kept an eye on the temperature gauge and it stays consistant. It seems once it gets up to 220 the squealing is not as loud.
