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

An initial symptom of a failing fuel injector is a rougher engine idle and a slight reduction in power. If left unaddressed, fuel economy will noticeably decrease, and the engine may begin to misfire under load. Continued operation with a faulty injector can lead to increased internal engine wear and potential damage to other components.

Installation Tip

Ensure the injector bore in the cylinder head is meticulously clean before installing the new injector to prevent leaks and ensure proper sealing. Avoid rotating the injector during installation, as this can damage the sealing surfaces.

Service Note

When replacing a fuel injector, it is advisable to also replace the injector seal washers and inspect the fuel return lines for any blockages or leaks.
