Installation Notes and Tips
When installing the WAI 8316N alternator, ensure the serpentine belt is properly aligned with the 8-groove pulley to prevent slippage. Verify the rotation direction matches your vehicle’s requirements—this model rotates clockwise (right). Since the alternator includes an internal voltage regulator, no additional external regulator installation is necessary. Always disconnect the battery before beginning installation to avoid electrical shorts.
