DEF Filling Instructions
DEF Filling Instructions
Customers or dealers may have comments on adding fluid to the DEF tank. The capacity of the tank is 20‹›L (5.3‹›gal) and the trucks are shipped with
7.5‹›L (2‹›gal) from assembly. During PDI, it may be possible to add more than the approximate 13‹›L (3.5‹›gal) of remaining capacity. Most likely this
is related to the filling procedure. Customers may also be able to fill the tank more than 20‹›L (5.3‹›gal).
DEF basically behaves like water and will freeze at -11°C (12°F) and will expand. This does not normally cause a problem if the DEF tank is not
overfilled. Adding more than the 20‹›L (5.3‹›gal) usable capacity may not allow for DEF expansion when frozen.
To prevent damage from freezing, during PDI do not add more than the 13‹›L (3.5‹›gal) allowed during PDI. This should be done just before delivery to
the customer.
Tip
To maximize driving range and to prevent over filling the tank, wait until the "Exhaust Fluid Range: 1000 miles (approximate) (1609 km)" message
appears on the DIC. At this point, add up to 13 L (3.5 gal). Do not add more than 13 L (3.5 gal) of DEF. When using the CC&A DEF 3.78 L (1 Gal)
88862659 (88862660 (Canada) or 9.46 L (2.5 Gal) 88863523 (88863524 (Canada) fluid with the nozzle properly installed, when fluid reaches the top of
the fill pipe, stop filling. Instructions are provided on the bottle for proper nozzle installation. If another source of DEF is being used, when fluid initially
reaches the top of the fill pipe, stop filling and do not force additional fluid into the tank.
Frozen Tank Status
Condition
In operating temperatures of 15°F (-9°C) or less, customers may comment on an "Exhaust Fluid Range" message displaying on the DIC even though the
DEF fluid has been filled.
