Engine Block Heater: Description
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 core hole (in place of a core hole plug) in the engine block, with the heating element immersed in coolant.
