Installation Notes and Tips

Verify pulley type, rotation, clock position, and amperage before installation. This alternator uses a 6-groove serpentine pulley, clockwise rotation, and a 2:00 clock position, so matching the original unit is important for proper fitment. Confirm the vehicle’s charging system specification and connector layout against the removed alternator before replacement.
