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

LubricationLubricating systemOn-vehicle inspection1. Check oil level.During engine warming up and after it flames out for 5 minutes, check oil level, and the level should
be between two marks on oil dipstick at the moment.If oil level is too low, check there is leakage, and
refill oil up to upper mark on oil dipstick.
Note: oil level should not be above upper mark on oil
dipstick.2. Check oil quality.(a) Check there is deterioration, water penetration, color
change or thinning with oil.
(b) If oil quality becomes poor, please replace with new oil.
Hint: oil grades: API, SH, SJ, SG grade oil or ILSAC
multigrade oil. Recommended viscosity is
shown as below.

Oil filter assemblyReplacementWarning:Long-term or repeat contacting mineral oil will cause decomposing of natural fat on skin, which
will result in dry and sensitive skin and skin rankling. Used oil has potential harm and may cause
carcinoma cutis.When replacing engine oil, always wear protective clothes and gloves to avoid waste oil
penetrating, and reduce the frequency and time of skin contacting waster oil, and clean with
soapy water or clean water not with gasoline, thinner or solvent if skin contacts waste oil.To protect environment, waste oil and oil filter must be abandoned at named place.1. Remove engine right bottom shield.
2. Discharge engine oil.
3. Remove oil filter assembly [4G18-1012100].Remove oil filter with special tool.4. Install oil filter assembly.(a) Check and clean oil filter junction plane.
