DEF Tank Inlet Screen — Installation

CAUTION: Avoid possible personal injury. In case of DEF contact, immediately flush eyes with large amounts of water for a minimum of 15 minutes. Reference the Materials Safety Data Sheet (MSDS) for additional information.

Do not ingest DEF. In the event DEF is ingested, contact a physician immediately. Reference the Materials Safety Data Sheet (MSDS) for additional information.

IMPORTANT: Avoid corrosion of vehicle parts or surfaces. If DEF is spilled or contacts any surface other than the storage tank, immediately clean the surface with clear water. DEF is corrosive to painted and unpainted metallic surfaces and can distort some plastic and rubber components.

Spilled DEF, if left to dry or if only wiped away with a cloth, will leave a white residue. Improperly cleaned DEF spill may interfere with diagnosis of Selective Catalytic Reduction (SCR) system leakage problems.

  1. Thoroughly clean the area around the DEF tank inlet for any debris.

  2. If there is any evidence that debris has entered the DEF tank, the tank must be drained and thoroughly cleaned.

  3. Carefully insert DEF tank inlet screen (A) into DEF tank.

  4. Ensure DEF tank inlet screen clicks and locks into place.
