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 injector may initially present as a noticeable drop in engine power or an increase in black smoke from the exhaust. If ignored, this can progress to rough idling, misfires, and increased fuel consumption. Continued operation with a faulty injector risks uneven cylinder wear and potential damage to the piston or cylinder liner.

Installation Tip

Ensure the injector cup or bore in the cylinder head is meticulously cleaned and inspected for any damage before installing the new injector. Avoid rotating the injector during installation, as this can damage the seals.

Service Note

Always replace the fuel filter and inspect the fuel lines for any signs of contamination or damage when servicing fuel injectors.
