Cooling - Cooling syste- 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. - 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.

On-vehicle inspection......................................
- 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.
