Figure illustrated above
describes the functioning of cooling system of an automobile. The
key components used in a cooling system are
pressure cap, heater
hoses, thermostat, heater core, reserve tank, lower hose,
transmission cooler, water pump, fan,
radiator and upper house. The
cooling system of a vehicle operates or functions by directing
liquid coolant via passages in the engine block and heads. After
that the liquid coolant which flows through passages absorb the heat
from an engine. Then this fluid passes through a rubber hose to
reach to the radiator. At this stage the hot liquid is cooled by air
stream entering the engine compartment via grills. Once it gets
cooled, then it goes back to engine and same process repeats again.
