Engine Fan Control
The engine fan switch on the dash has a
manual and an automatic mode. In the
manual mode, the engine fan will engage
until the switch is back into automatic
mode. In automatic mode, the engine fan
operation is controlled by the engine
computer.
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.
