WARNING
DO NOT work on or near the fan with
the
engine running. Anyone near the
engine fan when it turns on could be
injured. If it is set at MANUAL, the fan
will turn on any time the ignition key
switch is turned to the ON position. In
AUTO, it could engage suddenly with-
out warning. Before turning on the igni-
tion or switching from AUTO to MAN-
UAL, be sure no workers are near the
fan. Failure to comply may result in
death or personal injury.
CAUTION
DO NOT operate the engine fan in the
MANUAL
position for extended peri-
ods of time. The fan hub was designed
for intermittent operation. Sustained
operation will shorten the fan hub’s
service life as well as reduce fuel
economy.
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.
How to Set the Shutdown Timer
The Shut Down Timer must first be
enabled. Enabling the shutdown timer is
located in the Settings Sub-menu.
Follow these steps to turn on the engine
idle shutdown timer. The shutdown timer
will default to 5 minutes (or the last value
used) and can be set up to 30 minutes
unless limited by the Engine Shutdown
System (Clean Idle on page 316)
