Jeep Wrangler: STARTING AND OPERATING / ENGINE BLOCK HEATER — IF EQUIPPED

The engine block heater warms the engine, and permits quicker starts in cold weather. Connect the cord to a standard 110-115 Volt AC electrical outlet with a grounded, three-wire extension cord.

Diesel Engine Block Heater Cord Location

The engine block heater cord is found under the hood bundled up next to the Power Distribution Center (PDC).

For diesel engines, its use is recommended for environments that routinely fall below -10°F (-23°C). It should be used when the vehicle has not been running for long periods of time and should be plugged in two hours prior to start. Its use is required for cold starts with temperatures under -20°F (-28°C).

The engine block heater cord is found under the hood bundled in front of the battery tray.
