Engine Block Heater: Description and Operation
Engine Block Heater - 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.
