Diesel Exhaust Fluid

Diesel exhaust fluid (DEF) is used in the ATS to
lower NOx in the exhaust stream. DEF is colorless
and close to odorless (it may have a slightly pungent
odor similar to ammonia). It is nontoxic, nonflam-
mable, and biodegradable. It is mildly corrosive to
aluminum, but does not affect the strength or struc-
ture of the aluminum.
White crystals may be noticeable around compo-
nents that come into contact with DEF. The crystals
are easily removed with water.
DEF consumption varies depending on ambient con-
ditions and vehicle application.
Freezing Conditions
DEF freezes to slush at around 12°F (-11°C). It is not
damaged or destroyed if frozen, and is fully usable
when thawed. The DEF in the tank is allowed to
freeze while a vehicle is non-operational. At start-up,
normal operation of the vehicle is not inhibited if the
