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
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.
(f) If coolant level is too low, please perform the above steps again.
(g) If coolant level is not too low, please adjust expansion tank coolant level.3. Check there is leakage with coolant.(a) Refill engine coolant to radiator, and install radiator cap tester.
(b) Pressurize radiator to 118kPa, and check there is leakage.73Engine drain valve
