This replacement pulley is also designed and produced by Litens and is exact in all form, fit, and performance characteristics as the original equipment part (with the exception of not having the car manufacturer's logo or part number applied to the part).

With reference to your inquiry on the Litens Overrunning Alternator Decoupling (OAD) Pulley - Original Equipment Quality -part# 920810A, the pulley on the alternator may be the problem. However, without the presence of the vehicle we could neither diagnose the problem nor provide you with a 100% answer. I would suggest you to get assistance from a certified mechanic for a proper diagnosis before buying and having parts installed that may not (solve/be) the problem. For any further assistance, you may also call us at: 1-877-238-2623 or visit the nearest Advance Auto Parts store and one of our Parts Pros will gladly assist you with any questions or concerns you may have.
