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.
Radiator Cap Air Leakage
1. Set a radiator tester (1) and an adaptor (2) on the radiator cap.
2. Apply the specified pressure (88 kPa, 0.9 kgf/cm
measure the time for the pressure to fall to 59 kPa (0.6 kgf/cm
9 psi).
3. If the measurement is less than the factory specification,
replace the radiator cap.

(1) Radiator Tester
Radiator Water Leakage
1. Pour a specified amount of water into the radiator.
2. Set a radiator tester (1) and an adapter (2) 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.
When water leak is excessive, replace the radiator.

Thermostat Valve Opening Temperature
1. Suspend the thermostat in the water by a string with its end
inserted between the valve and seat.
2. Heating the water gradually, read the temperature when the
valve opens and leaves the string.
3. Continue heating and read the temperature when the valve
opens approx. 8.0 mm (0.31 in.).
4. If the measurement is not within the factory specifications,
replace the thermostat.
