Engine Fan Switch

The engine fan switch allows you to control the engine fan
manually or automatically. With the ignition key switch ON
and the fan switch in the ON position, the engine fan will
be on regardless of engine temperature. With the engine
fan switch in the AUTOMATIC position, the engine fan will
automatically turn on when the engine coolant reaches a
temperature of about 200
°F.
WARNING! Do not work on the fan with the
engine running. Anyone near the engine fan
when it turns on could be badly injured. If it is
set at ON, it will turn on any time the ignition
key switch is turned to the ON position. In
AUTOMATIC, it could engage suddenly with
-
out warning. Before turning on the ignition or
switching from AUTOMATIC to ON, be sure no
one is near the fan.
CAUTION: The fan or equipment near it could
be damaged if the fan turns on suddenly when
you don’t expect it. Keep all tools and equip
-
ment such as rags away from the fan, and take
care no one turns on the ignition when some
-
one is working near the fan.
CAUTION: Do not operate the engine fan in
the manual (ON) 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.
