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.
