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

The first indication of failing injector sleeves might be a slight misfire or a subtle increase in exhaust smoke. If ignored, this can lead to significant power loss, poor fuel economy, and potential engine overheating. Continued operation risks damage to the cylinder head and injector components.

Installation Tip

Ensure the injector bore in the cylinder head is meticulously clean and free from any carbon buildup or debris before attempting installation. Avoid using excessive force or improper tools when seating the new sleeves, as this can cause damage.

Service Note

Inspect fuel injectors for proper sealing and spray pattern when replacing these sleeves.
