Pre-2013 DEF supply lines are electrically-heated
and are purged when the engine is shut down; com-
plete purging of the DEF lines requires approximately
five minutes after the engine is shut down.
DEF supply lines with engine model year 2013 and
newer are designed to survive freezing conditions
while containing DEF, so purging is not required.
DEF Tank
Engines that are compliant with EPA10 and newer
regulations are equipped with a DEF tank located on
the driver’s side of the vehicle behind the battery box
or forward of the fuel tank. See
Fig. 12.7
and
Fig. 12.8
. The DEF tank has a 19 mm filler neck inlet
that prevents the hose from a diesel outlet from
being inserted, and has a blue cap for easy
identification.
Fuel/DEF Gauge
The diesel fuel and DEF levels are measured in a
dual-purpose gauge. See
Fig. 12.9
.
Fuel level is indicated at the top of the gauge. Below
the fuel level, a low fuel warning lamp illuminates
amber when the fuel level drops below 1/8th of the
capacity.
The lower portion of the gauge has a DEF warning
lamp that illuminates amber when the DEF tank is
near empty, and a lightbar that indicates the level of
DEF in the tank. The DEF light bar illuminates as fol-
lows.
•
Four bars illuminated green—Between 75%
and 100% full
•
Three bars illuminated green—Between 50%
and 75% full
•
Two bars illuminated green—Between 25%
and 50% full
