Introduction
Do not perform any of the following procedure or order parts until you have read and understand the procedure. The procedure that follows below covers that installation of the new Diesel Exhaust Fluid (DEF) filter.Required Parts
Table 1 below contain the parts needed to complete the installation of the new DEF filter.Note: Only one DEF filter group is required per engine. Use Table 2 to determine which filter is the appropriate filter for each DEF header. Illustration 1 shows the location of the DEF header part number.

(1) DEF header
(2) DEF filter
(3) DEF tank
(4) DEF header bolts
Clean the area around DEF header (1). Clear any dirt or debris that could contaminate the DEF tank or lines when removed. Note: If proper cleaning is not performed, DEF pump performance issues or failure may occur.
Disconnect the two DEF lines, two coolant lines, and harness from the DEF header assembly.
Remove the six DEF header screws (4) from the DEF header assembly. Note: Do not discard the screws that secure the DEF header assembly to the DEF tank. The screws will be reused in a later step.
Remove the DEF header assembly. Remove the previous DEF header gasket and discard.

(5) 452-6055 Filter Base As
Install filter base assembly (5) onto the DEF header assembly. Note: Each half of the adapter has two small locking tabs that secure to the bottom side of the DEF header assembly.
Remove the previous 425-0385 Filter As located at the bottom of the DEF pick-up tube.
Install the new 425-0385 Filter As onto the DEF header assembly.

(6) Band clamp
Install the correct DEF filter onto the DEF header adapter and secure using band clamp (6) that is supplied. Torque the band clamp to 4.5 0.7 N m (40 6 lb in).
Install the DEF header assembly back into the DEF tank. Secure the DEF header to the DEF tank using the six screws previously removed in Step 3. Torque the six screws to 5 1 N m (44 9 lb in).
Reconnect the harness, coolant lines, and DEF lines to the DEF header.

(7) DEF pump inlet filter fitting
(8) Main DEF pump filter
Replace DEF pump inlet filter fitting (7) and main DEF pump filter (8). Refer to Disassembly and Assembly, UENR0132, "Diesel Exhaust Fluid Filter - Remove and Install" for the replacement procedure.
