2) Leak Test

Release the pressure in the system by 

loosening the pressure cap of the coolant 

reservoir slightly. Then, remove the pressure 

cap completely.

1.

Never open the cap until the coolant 
temperature becomes under 90℃ to 

prevent any burn.

Add the coolant so that the coolant level is 

between MAX and MIN mark on the coolant 

auxiliary tank.

Connect the tester to the tank filler and apply 

pressure (1.4 bar).

Check all the coolant hoses, pipes and 

connections for leaks when the pressure of 

the tester drops, and replace or tighten, if 

necessary.

3) Thermostat

Immerse the thermostat into the water. Heat the 

water and check the valve opening 

temperature.

3. CAUTIONS

If 100% of anti-freeze is added, the water pump vane can be damaged and thermal conductivity 

can be decreased resulting in poor circulation in the cooling system which leads to overheated 

engine.

Use of non-recommended coolant could cause damage to the cooling system and overheating of 

the engine.

Opening the coolant reservoir cap while the engine is running or hot can cause burns by hot 

steam or water. 

To open the coolant reservoir cap, wrap the cap with a wet towel or thick cloth after the engine is 

cooled down sufficiently.

If cool water is added to the heated engine, the engine or radiator can be deformed.

The anti-freeze in the coolant can damage the painted surface, so avoid the contact of the coolant 

to the painted body.

The anti-freeze and water should be mixed in proper mixture ratio. Never add only water when 

adding coolant.

If the anti-freeze content is too low, the coolant can be frozen while the engine can be overheated 

if anti-freeze content is too high.

Coolant reservoir

Oil filter module

Thermostat

When the engine coolant 
reaches 90℃, the thermostat 
starts to open (fully open at 
100℃) and lets the coolant 
flow to the radiator to maintain 
the engine temperature.

Water pump

The water pump is driven by the engine drive belt and supplies 
the coolant to each area of the engine.

Coolant temperature sensor

Measures the coolant 
temperature and sends the 
result to the engine ECU.

Electric fan

Circulates the fresh air forcibly to exchange heat 
with the radiator core fin.

Radiator

Releases heat through fins and cools down the hot 
coolant as the coolant passes through the tube of the 
radiator core.
