Cooling - Cooling syste
Temperature Degree of valve opening
(a)Immerse temperature regulator into water and heat
gradually.
(b) Check opening temperature of valve.
Opening temperature of valve: 80 84
Hint: if opening temperature of valve is not within
specified range, it is required to replace tempera-
ture regulator.
(c) Check opening of valve.
Opening of valve:
2. Radiator cap assembly
Notes:
If radiator is dirty, wash it with clean water.
Before using radiator cap tester, dampen relief valve
and pressure valve with coolant or water.
(a) Use radiator cap tester to slowly pump radiator cap
tester, and check the air is released by vacuum valve.
Pumping speed: 1 time /(3 seconds or more)
Note: pump radiator tester with constant speed.
Hints:
Pumping speed: 1 time /(3 seconds or more)
If air could not be released by vacuum valve,
please replace radiator cap.
(b) Pump tester and check opening pressure of relief valve.
Standard opening pressure: 74-108KPa
Min. opening pressure: 59KPa
Note: pumping speed means that the speed could be increased after the first time pumping
speed (to close vacuum valve).
Hints:
Pumping speed: 1 time within 1 second
Max. reading of tester is opening pressure.
If opening pressure is less than min. value, please replace radiator cap.
Hint: if degree of valve opening is not within speci-
fied range, it is required to replace tempera-
ture regulator.
(a) When temperature regulator is at low temperature (below
), check valve is tightly closed.
Hint: if the valve could not be closed, it is required to
replace temperature regulator.
