CAUTION: The power cord must be secured in its retainer clips, and not positioned so it could contact linkages or exhaust manifolds and become damaged.
The block heater is operated by ordinary house current (110 Volt A.C.) through a power cord and connector located in the engine compartment. The heater is mounted in a bore in the engine block and held in place by a retaining clip.

The engine block heater is mounted in the cylinder block, near the right rear corner. The block heater is a dry cylinder type design and is powered by 110 volt AC. The power cord must be secured in its retainer clips, and not positioned so it could contact linkages or exhaust manifolds and become damaged.
Operation
When power is applied (110 volt A.C.) to the block heater, the heating element transfers heat through the aluminum engine block and into the coolant without directly penetrating the cooling system.
Diagnosis and Testing
ENGINE BLOCK HEATER TESTING
If unit does not operate, test power cord for continuity with a 110-volt voltmeter or 110-volt test light. Test heater element continuity with an ohmmeter or 12-volt test light.
