CAUTION
The fan or equipment near it could be
damaged
if the fan turns on suddenly
when you do not expect it. Keep all
tools and equipment away from the
fan.
Using a Winterfront
CAUTION
The use of a winterfront can result in
excessive
coolant, engine oil, and in-
take air temperatures, which may lead
to overheating and possible engine
damage.
CAUTION
A winterfront should only be used at
temperatures
below 40°F (4°C). Use
of a winterfront above 40°F (4°C) can
decrease life of cooling module com-
ponents. Remove winterfront as soon
as the ambient temp reaches 41°F
(5°C). The use of a winterfront above
40°F
(4°C) can result in excessive
coolant, engine oil, and intake air tem-
peratures, which may lead to over-
heating and possible engine or coolant
module damage and emissions non-
compliance.
The winterfront is designed to minimize the
temperature dif
ferences across the radiator
and reduce the possibility of cooling
module damage. Aftermarket winterfronts
may not provide the proper airflow
distribution and could cause cooling
module damage.
What is Engine Aftertreatment
Vehicles manufactured with diesel engines
have an Engine Aftertreatment System
(EAS) to control vehicle exhaust
emissions. The system consists of a Diesel
Particulate Filter (DPF), Selective Catalyst
Reduction (SCR), DPF Switch and warning
lights. The DPF will trap soot from the
engine exhaust gases. The SCR uses
Diesel Exhaust Fluid to reduce the levels of
NOx in the engine exhaust. The EAS will
periodically clean (regenerate) the DPF
.
Please refer to the Engine Aftertreatment
System Supplement provided with the
vehicle for more detailed description of
functionality and warnings.
