STARTING PROCEDURES
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 in-
stalled option. If your vehicle is not equipped, heater
cords are available from your authorized Mopardealer.
•A 12–volt heater built into the fuel filter housing aids
in preventing fuel gelling. It is controlled by a built-in
thermostat.
