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

A failing fuel injector may initially cause a slight hesitation or misfire during acceleration. If left unaddressed, the issue can progress to persistent rough idling, significant loss of engine power, and excessive black smoke from the exhaust. Continued operation with faulty injectors risks uneven cylinder wear and potential damage to other engine components.

Installation Tip

Ensure the injector seat in the cylinder head is perfectly clean and free of any carbon buildup before installation. Avoid overtightening the injector hold-down clamp, as this can distort the injector body and affect its spray pattern.

Service Note

Inspect the fuel filter and fuel lines for any signs of contamination or damage when replacing a fuel injector.
