Why a DEF Filter Matters
Diesel exhaust fluid is injected into the exhaust system to reduce emissions. Contaminants in DEF can clog the pump, injector and lines of the SCR system and trigger fault codes or reduced engine power. A DEF filter protects these components, and regular replacement helps avoid downtime and expensive repairs.

Installation and Maintenance Notes
- Switch off the engine, and follow the manufacturer’s safety instructions for the SCR and DEF system.
- Place a drain pan under the DEF pump module, and remove the filter cover or cap according to the service manual.
- Remove the old DEF filter and any used seals. Handle DEF carefully, since it can leave deposits and corrode some metals.
- Clean the filter housing with clean water. Do not use fuel, oil or other solvents.
- Install the new filter and seals from the kit, making sure everything seats correctly.
- Close the housing, and tighten to the torque specified in the service manual.
- Start the engine, check for leaks, and clear any fault codes if required. Replace the DEF filter at the interval recommended by the engine maker.
