DEF Tank
See Figure 7-10
DEF quality, level, and temperature are monitored by the
engine control module via sensors in the tank.
The DEF can be heated by engine coolant which is
circulated through a heat exchanger in the tank. If the tank
temperature drops below 25° F (–4° C), the DEF tank coolant
solenoid valve will be commanded open by the ECM, and
engine coolant will flow through the heat exchanger.
There is a 40-micron filter in the DEF supply (suction) pipe.
For filter maintenance intervals, refer to the Cummins engine
manual.
A drain valve is provided in case the tank needs to be
emptied of poor-quality DEF.
The DEF tank capacity is 10 gallons.
