INSPECTION AND REPAIR
2. Add the coolant up to upper mark (arrow) on the reservoir.
3. Install the tester to the coolant reservoir and apply the
pressure of 1.4 bar.
4. Check the coolant hoses, pipes and connections for leaks
after the pointer of the tester drops. Replace or retighten
as required.
Immerse the thermostat into the water. Heat the water and
check the valve opening temperature.

Cooling System
1. Release the pressure from coolant reservoir by loosening
one notch of coolant reservoir cap, and then remove the
cap.

INSPECTION
Notice
Scalding hot coolant and steam could be blown out
under pressure, which could cause serious injury.
Never remove the coolant reservoir cap when the
before the temperature goes down below 90
°°°°°C.

1. Immerse the senor unit into the water. Heat the water
and check the resistance.
2. If the measured resistance is out of specified value,
replace the gauge unit.
3. Measure the resistance between terminal A and gauge
unit housing, and terminal B and gauge unit housing.
1. Immerse the thermostat into the oil. Heat the oil until it
reaches the specified temperature and check if the
coolant temperature switch is turned “OFF”.
