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

Initial signs of failure may include a DEF system warning light on the dashboard or a 'reduced engine power' message. If ignored, the system may cease to function, leading to increased emissions and potential non-compliance with regulations. Continued operation with a faulty pump can result in the vehicle being unable to start after a shutdown.

Installation Tip

Ensure the DEF tank is clean and free of debris before installing the new pump to prevent immediate contamination. Avoid overtightening the mounting bolts, as this can strip the threads or crack the pump housing.

Service Note

Inspect the DEF injector and exhaust temperature sensors for proper operation when replacing the DEF pump.
