Installation Notes and Tips

Verify the vehicle’s original alternator specification before installation, especially amperage rating, rotation direction, pulley configuration, and regulator type.

Check belt alignment, electrical connectors, and battery condition before replacing the alternator to avoid repeat charging-system issues.
