2.3.3 RADIATOR
The radiator core consists of water carrying tubes (2) with
fi
ns (3) at a right angle to it. The water in the radiator is
cooled by the air
fl
owing through the tube wall and the
fi
n.
2.3.4 RADIATOR CAP
The pressure type cap is installed on the radiator and pre-
vents the radiator from being deformed, because of the
pressure difference between the inside and outside of the
radiator.
(A) At high pressure (over 88 kPa (0.9 kgf/cm
2
, 13 psi))
When the coolant temperature rises and the pressure in
the radiator increases over the specified pressure, the
pressure valve (1) opens to reduce the internal pressure.
(B) At low pressure
When the coolant temperature falls and a vacuum is
formed in the radiator, the vacuum valve (2) opens to allow
ambient air to enter the radiator.
