Radiator, Radiator Cap, Radiator Hoses
When the
water
leaves the engine,
it
is
so
hot that
it must be cooled before it can be
reused.
As the water
makes it
way
down through the
tubes
of the radiator,
it gives off heat to the
air via
the fins
,
and
becomes
cool
enough to reuse.
By
placing the
radiator
cap
(pressure cap)
on
the
radiator
filler
neck
,
the cooling system is presurized.

Spring
The cap has two valves.
One
is a pressure valve,
which
holds
the pressure in the radiator when the engine
is running and the water expands.
When
the pressure
exceeds the limit, the pressure valve no longer
holds
and
allows the
pressure
to release to the
reserve
tank. As
soon as pressure escapes, the valve closes, and keeps the
predetermined pressure
constant.
When the engine stops
and cools
down,
another small valve (vacuum valve) in
the cap opens. As the water cools, it contracts and tires
to form a vacuum in the radiator.
This draws the
vacuum valve open and allows the water from the re-
serve tank to enter the
radiator.
