HEATER-ENGINE BLOCK 

DESCRIPTION 

DESCRIPTION 

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. 

OPERATION 

OPERATION 

The block heater element is submerged in the cooling system's coolant. When electrical power (110 volt A.C.) 
is applied to the element, it creates heat. This heat is transferred to the engine coolant. This provides easier 
engine starting and faster warm-up when vehicle is operated in areas having extremely low temperatures. 

REMOVAL 

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.
