If its not leaking more then likely is the the idler or tension for the serpentine belt
look deeperIf it is a chirp or squeal noise, spray a little belt dressing or a little brake clean, silicone etc. on the inside and outside surfaces of the belt while it is running. If it stops you need a belt.If the noise is a growl, Take the tension off the belt and remove the belt. Spin the water pump pulley and feel for roughness. It should be smooth. Compare it the other pullies and feel for roughness. Spin them quickly and listen for roughness. Answercheck the belts and the idler/tensioner pulley and bearing combo...could be that...also...everyone should have a manual for their vehicle, and the local library should have a professional shop manual available, to make copies of, in the Reference section...good luck:)
AnswerThis is my question. I'm just adding more to it. I already replaced the serpentine belt. The noise quiets down when I turn the A/C on (with new and old belt). Could this be a sign of water pump replacement? The car does not overheat. ALSO, when my A/C is on MAX, it blows but then after awhile it kinda starts to drizzle, then it kicks back in. Could that have anything to do with it too? -THANKS!-Thanks.
