Extreme Cold Weather
The Cummins diesel engine is equipped with several
features designed to assist cold weather starting and
operation:
•The engine block heater is a resistance heater installed
in the water jacket of the engine just above and behind
the oil filter. It requires a 110–115 Volt AC electrical
outlet with a grounded, three-wire extension cord.
NOTE: The engine block heater cord is a factory installed
option. If your vehicle is not equipped, heater cords are
available from your authorized MOPAR dealer. •
A 12 Volt heater built into the fuel filter housings aid in
preventing fuel gelling. It is controlled by a built-in
thermostat.
• A heated intake air system both improves engine
starting and reduces the amount of white smoke
generated by a warming engine.
Normal Starting Procedure — Engine Manifold Air

STARTING AND OPERATING 205

Starting Procedure — 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” telltale has turned
off, but before the engine is started. However, excessive
cycling of the manifold heaters will result in damage to
the heater elements or reduced battery voltage.
NOTE:If multiple pre-heat cycles are used before start-
ing, additional engine run time may be required to
maintain battery state of charge at a satisfactory level.
1. If the engine stalls after the initial start, the ignitionmust 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.
2. 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” telltale turns
off and the engine is started, recycle the manifold
heaters by turning the ignition switch to the OFF
position for at least five seconds and then back ON.
3. 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 heat-
ers will shut off.
4. If the engine is started before the “Wait To Start” telltale turns off, the preheat cycle will turn off.
5. If the engine is cranked for more than 10 seconds, the post-heat cycle will turn off.
206 STARTING AND OPERATING

NOTE:
•Engine idle speed will automatically increase to
1,000 RPM and engage the Variable Geometry Turbo-
charger at low coolant temperatures to improve engine
warm-up.
• When a diesel engine is allowed to run out of fuel or
the fuel gels at low temperatures, air is pulled into the
fuel system. If your engine has run out of fuel, refer to
“Maintenance Procedures/Priming If The Engine Has
Run Out Of Fuel” in “Maintaining Your Vehicle” for
further information.
• If the engine stalls, or if the ignition switch is left ON
for more than two minutes after the “Wait To Start”
telltale goes out, reset the grid heaters by turning the
ignition switch to the OFF position for at least five
seconds and then back ON. Repeat steps 1 through 5 of
“Starting Procedure – Engine Manifold Air Tempera-
ture Below 66°F (19°C).”Starting Fluids
WARNING!
Starting fluids or flammable liquids must never be
used in the Cummins diesel engine (see Warning
label). Never pour diesel fuel, flammable liquid,
starting fluids (ether) into the air cleaner canister, air
intake piping, or turbocharger inlet in an attempt to
start the vehicle. This could result in a flash fire and
explosion causing serious personal injury and engine
damage.
The engine is equipped with an automatic electric air
preheating system. If the instructions in this manual are
followed, the engine should start in all conditions.
