ACDelco GM Original Equipment Serpentine Belts are designed, engineered, and tested to rigorous standards, and are backed by General Motors.

Some ACDelco GM Original Equipment parts may have formerly appeared as GM Genuine Parts (OE) or ACDelco Professional. ⚠ WARNING: Cancer and Reproductive Harm - https://www.P65Warnings.ca.gov
