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
