Engine Coolant Heater
Check Operation
NOTE: The engine coolant heater is an option that is
installed with the arctic starting system. This
procedure does not need to be performed if the
engine coolant heater is not installed.
Operate the optional engine coolant heater to keep
the unit functioning correctly. This procedure should
be performed before the engine is started in the
morning, while the engine coolant is still at ambient
temperature.
NOTE: Do not start the engine.
1. Press engine coolant heater switch (1) to turn the
system on. The lamp inside the coolant heater
switch will turn on when the system is operating.
2. Allow the engine coolant heater to operate for 10 or
15 minutes, and then press engine coolant heater
switch (1) again to turn the coolant heater off.
3. Wait until the lamp inside the coolant heater switch
turns off (at least three minutes) before starting the
engine.
NOTICE
Do not start the engine while the light in the engine
coolant heater switch is on. The engine coolant heater
requires three minutes to purge itself of diesel fumes.
Damage to the engine coolant heater may result if the
engine is started too soon after use.
