COLD WEATHER STARTING

When starting a cold engine, the intake air
should be warmed up by using the intake air
preheater. Turn the ignition switch to the ON
position. The preheater will not engage at
coolant temperature above 54°F (12°C). If the
coolant temperature is below 54°F (12°C), the
preheater will engage and will light the preheater
telltale between 0 and 50 seconds, depending
on the engine coolant temperature. Wait before
the preheater telltale has turned off before
starting the engine.
If necessary, once the engine has started, the
preheater will reengage (post heating) for the
same length of time as the preheat time.
Do not use ether or other combustible starting
aid fluid on any engine equipped with an
intake air preheater. If the engine is equipped
with a preheater, introduction of ether or
similar starting aids could cause a fire or
explosion
damage, serious personal injury or death.
