DEF Removal Procedure
Note: For Diesel Exhaust Fluid (DEF) handling and storage procedures, refer to Operation and Maintenance Manual, Fluid Recommendations for more information.
Clean the DEF tank of all debris prior to removal of any component. Contamination of the DEF can affect results of testing.
Illustration 1 g03706721
Typical example
(1) DEF tank fill cap
(2) Filter screen
Remove fill cap (1) from the Diesel Exhaust Fluid (DEF) tank.
Use Tooling (J) to press and release the tabs. With the tabs released, remove the filter screen (2) from DEF tank neck adapter.
Illustration 2 g03706724
Typical example
(3) Vacuum pump nut
(4) Tooling (D)
( 5) Tooling (H)Note: To ensure that the DEF sample is not contaminated during extraction, use a new piece of Tooling (H) every time this procedure is performed.
Remove Tooling (H) from the plastic bag and install into Tooling (D).
Loosen nut (3) in order to install Tooling (H).
Install Tooling (H) all the way through the cap of the vacuum pump as shown in Illustration 2.
Tighten the nut on top of the vacuum pump down completely to prevent DEF leaks.
Remove Tooling (C) from the plastic bag. Remove the cap and install Tooling (C) onto Tooling (D).
Illustration 3 g03706727
Typical example
(5) Tooling (H)
( 6) DEF tank filler neckNote: The DEF sample must only be taken from the top level of fluid that is contained in the DEF tank. The top level of the DEF is where the contaminants will be located.
Place the other end of Tooling (H) into the filler neck of DEF tank (6).
Extract DEF from the top level of fluid in the tank using Tooling (D). Fill Tooling (C) to the "Fill Line" that is on the bottle.
Proceed to"Test Procedure For DEF Contamination" to begin contamination testing.Test Procedure For DEF Contamination
Place Tooling (G) into Tooling (C) for 5 seconds.
Illustration 4 g03707382
(7) Negative test result
(8) Positive test result
Remove Tooling (G) and look for discoloring as shown in Illustration 4. Any discoloring of Tooling (G) indicates DEF contamination by an oil-based fluid. Contact the Dealer Solution Network (DSN) for further information.Note: If the test strips indicate no DEF contamination, proceed to "Test Procedure For DEF Concentration".Test Procedure For DEF Concentration
Illustration 5 g03370564
A typical example of Tooling (A)
Illustration 6 g03370553
Calibration point for distilled water
Follow the instructions included with Tooling (A) to calibrate the waterline of the meter.
Clean Tooling (A) and apply two drops of Diesel Exhaust Fluid (DEF) collected from the DEF tank.
Illustration 7 g03370573
Typical reading for DEF in good condition
Inspect the DEF in Tooling (A). The DEF quality must measure between 29 and 35 percent. If the DEF does not meet specification, replace the DEF in the tank with new DEF. Refer to Operation and Maintenance Manual for more information. The new DEF must meet ISO 22241 standards.Note: Dispose of the DEF removed as per local regulations and mandates.
