Fluide d'échappement diesel
en climat froid
Due to the freezing point of Diesel Exhaust Fluid
(DEF) the aftertreatment system is equipped with
electrically heated DEF lines. The system also has a
coolant heated element in the DEF tank and DEF
pump.
During periods of weather in which DEF can freeze
the application should be stood on level ground when
not in use. DEF can start to freeze at −11° C
(12.2° F).
Nota: At certain angles DEF can cover the DEF filler
cap. If the DEF freezes, the DEF tank vent could
block. A blocked vent in the DEF tank assembly will
cause operational difficulties.
For information on DEF refer to this Operation and
Maintenance Manual, "Fluid Recommendations".
