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.

The engine block heater cord is located:

• 3.6L Engine – coiled and strapped to the engine oil dipstick tube.

• 5.7L Engine – bundled and fastened to the injector harness.

The engine block heater must be plugged in at least one hour to have an adequate warming effect on the engine.

WARNING!
Remember to disconnect the engine block heater cord before driving. Damage to the 110-115 Volt electrical cord could cause electrocution.
