Diesel Fuel Filters/Water Separator - Jeep grand cherokee 2015 User Manual

Extreme Cold Weather
The engine block heater is a resistance heater installed in the water jacket of the
engine. It requires a 110–115 Volt AC electrical outlet with a grounded, three-wire
extension cord.
Its use is recommended for environments that routinely fall below -10°F. It should be used
when the vehicle has not been running overnight or longer periods and should be plugged
in two hours prior to start. Its use is required for cold starts with temperatures under -20°F.
A 12 Volt heater built into the fuel filter housing aids in preventing fuel gelling. It is
controlled by a built-in thermostat.
A Diesel Pre-Heat system both improves engine starting and reduces the amount of
white smoke generated by a warming engine.
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
