CAUTION
• When removing the radiator cap, wait at least 10 minutes after the engine has stopped and cooled down.
Otherwise, hot water may gush out, scalding nearby people.
Radiator Cap Air Leakage
1. Set a radiator tester and adaptor (BANZAI Code No.: RCT-2A-
30S) on the radiator cap.
2. Apply the specified pressure 90 kPa (0.9 kgf/cm
measure the time for the pressure to fall to 60 kPa (0.6 kgf/cm
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 and an adaptor (BANZAI Code No.:
RCT-2A-30S) and raise the water pressure to the specified
pressure.
3. Check the radiator for water leaks.
4. For water leak from the pinhole, repair with the radiator cement.
