Installation & Application Notes

Inspect mating surfaces for wear before fitting. Use torque specs from service manual. Replace gaskets and seals as a set — reusing compressed gaskets causes oil leaks. Clean all oil passages with compressed air.

Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.

Failure Symptoms

Early signs of alternator failure include a battery warning light appearing on the instrument panel or a noticeable dimming of headlights and interior lights. If ignored, the battery will eventually discharge completely, leading to a complete loss of electrical power and engine shutdown. Continued operation without a functioning alternator risks damaging sensitive electronic components due to voltage fluctuations.

Installation Tip

Always disconnect the battery before beginning alternator replacement to prevent electrical shorts. Ensure the new alternator's pulley aligns perfectly with the drive belt and crankshaft pulley.

Service Note

Inspect the drive belt and belt tensioner for wear and proper function; replace if necessary.
