Cooling - Cooling systeTemperatureDegree of valve opening(a) Immerse temperature regulator into water and heat
gradually.
(b) Check opening temperature of valve.
Opening temperature of valve: 8084Hint: 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 assemblyNotes: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 secondMax. 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.67

Cooling - Cooling fan systemCooling fan systemOn-vehicle inspection1. Check cooling fan function at low temperature (below 95).(a) Turn ignition switch to ON.
(b) Check cooling fan is stopped.
Hint: if it is not stopped, check cooling fan relay and water temperature sensor, or check the
joint or wire harness between them.
(c) Uncouple water temperature sensor joint.
(d) Check cooling fan runs.
If it does not run, check fuse, cooling fan relay, engine ECU and cooling fan, or check there is short
circuit between them.
(e) Connect back water temperature sensor joint.2. Check cooling fan function at high temperature (above 95).(a) Start engine and increase coolant temperature up to above Hint: water temperature is the value measured by water temperature sensor on water outlet.
(d) Check cooling fan runs.
Hint: if it does not run, please replace water temperature sensor.3. Check cooling fan.(a) Uncouple cooling fan joint.
(b) Connect battery and ampere meter to cooling fan joint.
(c) Check cooling fan runs normally and check ampere meter reading.Standard current: 712A
(d) Connect back cooling fan joint.Inspection1. Electronic fan relay [67000064]

CoolantReplacement1. Discharge engine coolant.Warning: when the temperature of engine and radiator is high, do not remove radiator cap to
avoid being scalded, because coolant and steam will spurt under high pressure.
(a) Remove radiator cap.
(b) Open radiator drain valve and engine drain valve.Cooling - Coolant2. Refill engine coolant.(a) Lock 2 drain valves and pour coolant into radiator until it is full.
Hints:Press radiator water inlet hose and outlet hose with hands several times.If coolant level is too low, please refill coolant again.
(b) Screw down radiator cap.
(c) Pour coolant into expansion tank until the level is up to “FULL” mark line.
(d) Run engine with vehicle warning up until thermostat valve is opened.
Hint:During vehicle warning up, press radiator water inlet hose and outlet hose with hands
several times.
(e) Engine flames out until coolant temperature falls to “cold”. Then open radiator cap and check coolant
level.
