Last week I installed my underdrive pulley's and now im getting a loud squeaking noise coming from that area. Im not sure if its the pulley's themselves or if its the new serpintine belt I put on with the pulley's. Is this normal with new pulley's or a new belt? would some belt dressing fix this or can I do something else to quiet it down. the car runs great and the noise is not effecting performance. Can I get some help guys?
