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

Note
1. Do not dispose Refrigerant in sealed space or near
flame.
2. Wear glasses to protect your eyes.
3. Do not let liquid Refrigerant contact with your eyes
or skin.
If liquid Refrigerant contacts with your eyes or skin:
(a) Wash the contacted part with much water.
Warning: do not knead your eyes or skin.
(b) Spread clean Vaseline on your skin.
(c) Go to doctor or hospital for special cure.
4. Forbid heating it or making it expose the flame.
5. Forbid dropping the Refrigerant tank or shake it
intensively.
6. Do not operate compressor when Refrigerant is lack.
If the Refrigerant in cooling system is lack, it will incur com-
pressor burned out for lacking lubrication. So it is necessary
to avoid.
7. Do not open the high pressure valve of filling instru-
ment package when compressor is working.
If opening the valve at this time, Refrigerant will flow back into
refrigerant tank to incur the tank will break. So only the low
pressure valve could be opened or closed.
8. Do not fill Refrigerant too much.
Too much refrigerant will make many problems such as lack
cooling degree, oil consumption, too hot engine and so on.
Inspection on automobile
1. Check the No.1 pressure switch.
(a) Control for electromagnetic clutch:
Check the function of pressure switch.
(1) Assembly filling instrument package.
(2) Connect the anode lead of OUM meter to No. 4 termi-
nal and connect cathode lead to No. 1 terminal.
(3) Liking that shown in figure. When refrigerant pressure
is changed, check the conduction between terminals.

If resistance does not accord with the regulation, it is necessary to change heat sensitive resistance.
If the function does not accord with the regulation, it is
necessary to change pressure switch.
(b) Control for cooling fan:
Check the function of pressure switch.
(1) Connect the anode lead of OUM meter to No. 2 termi-
nal and connect cathode lead to No. 3 terminal.
(2) Liking that shown in left figure. When refrigerant pres-
sure is changed, check the conduction between
terminals.
If the function does not accord with the regulation, it is
necessary to change pressure switch.

When cooling system is
working, the pressure in low
pressure end changes to
vacuum or normal periodically.Water vapor enters refrigerant
system, and freezes on the ex-
pansion valve, the system
stops cycle in short time, when
ice melts, it returns to normal
again.(1)Change the condenser.
