Radiator Cap Air Leakage
CAUTION
• Remove the radiator cap only after you stop the engine for
a minimum of 10 minutes to decrease its temperature. If
not, hot water can gush out and cause injury.
1. Set a radiator tester and an adaptor on the radiator cap.
2. Apply the specified pressure 90 kPa (0.9 kgf/cm
3. Measure the time for the pressure to decrease to 60 kPa
2
(0.6 kgf/cm , 9 psi).
4. If the measurement is less than the factory specification,
replace the radiator cap.

Radiator Water Leakage
1. Fill a specified quantity of water into the radiator.
2. Set a radiator tester and an adaptor on the radiator. Increase

tester and adaptor.
3. Check the radiator for water leakage.
4. For water leakages from the pinhole, replace the radiator or
