Engine mechanismEngine assemblyInspection1. Check coolant.
2. Check engine oil.
3. Check battery.
4. Check air filter assembly.
5. Check spark plug [4G18-3705113].
6. Check drive belt [4G18-1307107].Hint: do not check belt tension, because automatic tensioner is applied.7. Check ignition timing.(a) Warm up engine.
(b) Connect timing lamp to engine.
(c) Check ignition timing at idle speed.
Ignition timing: before top dead center Note: when checking ignition timing, place
transmission at neutral position.
Hint: After run the engine for 5 seconds with rotating
speed of 1000-1300rpm, check the engine could
recover to idle running.8. Check engine idle speed.(a) Warm up engine and run it at idle speed.
(b) Read engine rotating number in data flow with diagnostic instrument.
(c) Check idle speed.
Idle speed: about 750-850rpm
Notes:When checking idle speed, place cooling fan at OFF position.Turn off all auxiliary devices and air conditioner.Engine mechanism - Engine assemblyK-line 26

Cooling - Cooling syste2. Check engine coolant level in reservoir.Engine coolant level should be between “Low” and “Full” mark line.
Hint: if the level is too low, check there is leakage and refill coolant to “Full” mark line.3. Check engine coolant quality.(a) Remove radiator cap.
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.
(b) Check there is too much rust deposit around radiator cap or at outlet and check there is flake; there
should not be oil in the coolant.
Hint: if coolant is too dirty, it is required to replace coolant.
(c) Install back radiator cap.Inspection1. Temperature regulatorHint: the figure on temperature regulator is the
opening temperature of valve.CoolingCooling systemOn-vehicle inspection1. Check there is leakage with cooling system.Warning: when the temperature of engine and radiator is
high, do not remove radiator cap to avoid be-
ing scalded, because coolant and steam will
spurt under high pressure.
(a) Refill coolant to radiator, and install radiator cap tester.
(b) Preheat engine.
(c) Pump tester to make pressure go up to 118KPa, and check
the pressure falls.
Hint: if the pressure falls, check there is leakage with
hose, radiator or water pump, and check heater,
cylinder body and cylinder head if no external leak-
age is found.66

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]
