Installation Notes and Tips

Verify the vehicle’s original amperage rating, pulley groove count, plug type, and rotation direction before installation. This alternator is not one-wire capable, and the application must match the listed Hyundai fitment and notes, especially where “to 90 Amp Alternator” or date limits are specified. Confirm belt alignment and connector fitment during replacement on Hyundai Elantra, Accent, Tucson, and Tiburon models.
