3.3.4 RADIATOR CAP

1
(1) Pressure valve
The pressure type cap is installed on the radiator, which
prevents the pressure difference between the inside and
the outside of the radiator from deforming the radiator.
(A) At high pressure(higher than 88 kPa (0.9 kgf/cm², 13
psi))
When the water temperature rises and the pressure in
the radiator increases above the specified pressure,
the pressure valve (1) opens to reduce the internal
pressure.
(B) At low pressure
When the water temperature falls and a vacuum is
formed in the radiator, the vacuum valve (2) opens to
allow the air to enter the radiator.
