Radiator Cap Air Leakage
CAUTION
• When removing the radiator cap, wait at least ten minutes
after the engine has stopped and cooled down. Otherwise,
hot water way gush out, scalding nearby people.
1. Set a radiator tester (Code No. 07909-31551) and an adaptor
(BANZAI Code No. RCT-2A-30S) on the radiator cap.
2. Apply the specified pressure 88 kPa (0.9 kgf/cm
2
, 13 psi), and
measure the time for the pressure to fall to 59 kPa (0.6 kgf/cm
2
,
9 psi).
3. If the measurement is less than the factory specification, replace
the radiator cap.

Radiator Water Leakage
1. Pour a specified amount of water into the radiator.
2. Set a radiator tester (Code No. 07909-31551) with an adapter
(BANZAI Code No. RCT-2A-30S) and raise the water pressure to
the specified pressure.
3. Check the radiator for water leaks.
4. If any water leaks are detected, replace the radiator or repair with
the radiator cement. If the water leak is excessive, replace the
radiator.
