EXTREME COLD WEATHER
The Cummins® Turbo Diesel engine is equipped with
several features designed to assist cold weather start-
ing 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 an 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.
•
An intake air heater system both improves engine
starting and reduces the amount of white smoke
generated by a warming engine.
NORMAL STARTING PROCEDURE —
ENGINE MANIFOLD AIR
TEMPERATURE ABOVE 66°F
(19°C)
Observe the instrument panel cluster lights when start-
ing the engine.
1. Always apply the parking brake.
2. Shift into PARK for an automatic transmission.
3. Place the ignition switch in the ON/RUN position
and watch the instrument panel cluster lights.
CAUTION!
If the Water in Fuel Indicator Light remains on, DO
NOT START the engine before you drain the water
from the fuel filters to avoid engine damage.
4. Place the ignition switch in the START position and
crank the engine. Do not press the accelerator dur-
ing starting.
CAUTION!
Do not crank the engine for more than 25 seconds at
a time or starter motor damage may result. Turn the
ignition switch to the OFF position and wait at least
two minutes for the starter to cool before repeating
start procedure.
5. Check that the Oil Pressure Warning Light has
turned off.
6. Release the parking brake.
STARTING PROCEDURE — ENGINE
MANIFOLD AIR TEMPERATURE 0°F
TO 66°F (–18°C TO 19°C)
NOTE:
The temperature displayed in the instrument cluster
does not necessarily reflect the engine manifold air
temperature
page 78. When engine temperatures
fall below 66°F (19°C) the Wait To Start Indicator Light
will remain on indicating the intake air heater system is
active.
Follow the steps in the “Normal Starting” procedure
except:
1. The Wait To Start Indicator Light will remain on for a
period of time that varies depending on the engine
temperature.
2. While the Wait To Start Indicator Light is on, the
instrument cluster will additionally display a gauge
or bar whose initial length represents the full “Wait
to Start” time period. Its length will decrease until it
disappears when the “Wait to Start” time has
elapsed.
CAUTION!
If the Water in Fuel Indicator Light remains on, DO
NOT START the engine before you drain the water
from the fuel filters to avoid engine damage.
3. After the Wait To Start Indicator Light goes off, place
the ignition switch in the START position. Do not
press the accelerator during starting.
CAUTION!
Do not crank the engine for more than 25 seconds at
a time or starter motor damage may result. Turn the
ignition switch to the OFF position and wait at least
two minutes for the starter to cool before repeating
start procedure.
4. After engine start-up, check that the Oil Pressure
Warning Light has turned off.
5. Release the parking brake and drive.
