This 24V DEF exhaust fluid pump is a critical component of the Selective Catalytic Reduction (SCR) system, responsible for injecting Diesel Exhaust Fluid (DEF) into the exhaust stream to reduce harmful emissions.

Failure Symptoms

The first indication of a problem is often a DEF system warning light or a message indicating reduced engine performance. If ignored, the pump may cease to function entirely, leading to increased emissions and potential engine shutdown by the vehicle's management system. Failure to address this issue will result in non-compliance with emissions regulations and inability to operate the vehicle.

Installation Tip

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

Service Note

When replacing the DEF pump, it is essential to inspect the DEF injector, lines, and filter for any signs of blockage or crystallization.
