This DEF exhaust fluid pump is integral to the Selective Catalytic Reduction (SCR) system on Volvo D12 and D16 engines, accurately delivering Diesel Exhaust Fluid (DEF) to the exhaust stream to reduce NOx emissions. It is built to meet stringent OEM quality standards for reliable and precise fluid delivery, unlike a clogged or failed pump. Operators may observe a check engine light related to SCR system faults, increased DEF consumption, or reduced engine power if the pump malfunctions.

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 a failing DEF pump may be a warning light on the dashboard related to the SCR system. If ignored, the system may cease functioning correctly, leading to increased emissions and potential engine derating. The ultimate consequence is the inability to operate the vehicle legally due to emissions non-compliance.

Installation Tip

Ensure the DEF tank is clean and free of any contamination before installing the new pump. Do not operate the pump dry; prime it according to the manufacturer's instructions if required.

Service Note

Flush the DEF lines and inspect the DEF injector for any signs of crystallization or blockage.
