Grand Caravan FWD V6-3.3L VIN 3 Flex Fuel (2002)
Engine Block Heater: Description and Operation
DESCRIPTION
The engine block heater is available as an optional accessory on all models. The heater is operated by ordinary house current (110 Volt A.C.) through
a power cord located behind the radiator grille. This provides easier engine starting and faster warm-up when vehicle is operated in areas having
extremely low temperatures. 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
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.
