For Extremely Cold Weather Starting — Engine
Manifold Air Temperature Below 0°F (-18°C)
In extremely cold weather below 0°F (-18°C) it may be
beneficial to cycle the manifold heaters twice before
attempting to start the engine. This can be accomplished
by turning the ignition OFF for at least five seconds and
then back ON after the WAIT TO START light has gone
off, but before the engine is started. However, repeated
cycling of the manifold heaters will result in damage to
the heater elements or reduced battery voltage.
Proceed by following the steps in the Normal Starting
Procedure.
NOTE: If multiple pre-heat cycles are used before
starting, additional engine run time may be required to
maintain battery state of charge at a satisfactory level.
•
If the engine stalls after the initial start, the ignition
must be turned to the OFF position for at least five
seconds and then to the ON position to recycle the
manifold heaters.
NOTE: Excessive white smoke and poor engine perfor-
mance will result if manifold heaters are not recycled.
•
Heat generated by the manifold heaters dissipates
rapidly in a cold engine. If more than two minutes
pass between the time the WAIT TO START light goes
OFF and the engine is started, recycle the manifold
heaters by turning the ignition OFF for at least five
seconds and then back ON.
•
If the vehicle is driven and vehicle speed exceeds 19
mph (31 km/h) before the manifold heater post-heat
(after start) cycle is complete, the manifold heaters will
shut off.
