C: INSPECTION
1) Remove the coolant filler tank cap, fill the cool-
ant filler tank with engine coolant, then install the
tester to the installation position of the cap.
2) Apply a pressure of 122 kPa (1.2 kg/cm
2
, 18 psi)
to the radiator and check the following points:
• Leakage from the radiator or its vicinity
• Leakage from the hose or its connections
CAUTION:
• Inspection must be carried out at the side of
coolant filler tank, not at the side of radiator.
• Engine should be turned off.
• Wipe engine coolant from check points in ad-
vance.
• Be careful of the spurt of engine coolant
when removing the tester.
• Be careful not to deform the filler neck of the
coolant filler tank when installing and removing
the tester.

Radiator Cap
COOLING
7. Radiator Cap
A: INSPECTION
1) Attach the radiator cap to tester.
2) Increase pressure until the tester gauge pointer
stops. Radiator cap is functioning properly if it holds
the service limit pressure for five to six seconds.
Remove the cap if it is opened under a pressure
less than the service limit value
Coolant filler tank side
Specification:
93 — 123 kPa (0.95 — 1.25 kg/cm
2
,
14 — 18 psi)
Service limit:
83 kPa (0.85 kg/cm
2
, 12 psi)
Radiator side
Specification:
122 — 152 kPa (1.24 — 1.55 kg/cm
2
,
18 — 22 psi)
Service limit:
112 kPa (1.14 kg/cm
2
, 16 psi)
CAUTION:
• Be sure to remove foreign matter and rust
from the cap in advance. Otherwise, results of
pressure test will be incorrect.
• Do not confuse the cap of coolant filler tank
and cap of radiator.
