Cleaning Diesel Exhaust Fluid (DEF) Tank
CAUTION: Avoid contact with eyes. In case
of 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.
IMPORTANT: 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, leaves a white residue.
Improperly cleaned DEF spill can interfere with
diagnosis of Selective Catalytic Reduction
(SCR) system leakage problems.
If foreign material or fluid has been added to the DEF
tank, drain the DEF tank, flush, and fill with new DEF.
If DEF quality is in question, pull a sample out of the DEF
tank and place into a clear container. DEF should be
crystal clear with a light ammonia smell. If DEF appears
cloudy, has a colored tint or has a profound ammonia
smell, it is likely not within specification. DEF in this
condition should not be used.
1. Remove drain plug (if equipped), and drain or siphon
bad DEF from DEF tank.
NOTE: Cleaning can take place with DEF tank
installed or removed.
2. Clean DEF tank with new DEF.
DEF must pass visual, smell, and concentration
checks before the engine can be ran. See Diesel
Exhaust Fluid (DEF) – For Use In Selective Catalytic
Reduction (SCR) Equipped Engines in the Fuels,
Lubricants, and Coolants Section for more information.
3. Drain or siphon DEF tank.
NOTE: Repeat steps 2—3 until DEF tank has
been cleaned.
4. Change DEF dosing unit filter.
5. Install drain plug in DEF tank, if removed. Install DEF
tank, if removed.
6. Fill DEF tank with new DEF.
7. Check DEF concentration with DEF refractometer,
such as JDG11594 or JDG11684. The correct DEF
concentration is 31.8% — 33.2%. See your authorized
dealer for more information.
8. If DEF is not within specification, does not appear
clear, or does not have a slight ammonia smell, contact
your authorized dealer.
