The Cummins® Turbo 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.
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.
