16000 SERVICE/MAINTENANCE MANUAL POWER TRAIN
DEF Tank
The 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 that is circulated
through a heat exchanger in the tank. If the tank temperature
drops below –4°C (25°F), 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 57 liters (15 gallons).
