Installation Notes and Tips

Verify pulley style, plug orientation, amperage rating, and whether the vehicle is equipped with A/C before installation. Confirm the alternator plug configuration and belt alignment against the original unit, especially on 1987-1990 Chevrolet and GMC applications with 4-pin or 11:00 plug notes. Match the vehicle’s charging system requirements to the Remy 91319 specifications before final installation.
