1) Coolant Level Check

Park the vehicle on level ground and apply the parking brake. Stop the engine and wait until it is

cooled down.

The coolant level should be between the MAX and MIN mark on the coolant reservoir.
Check the coolant level. If the level is below the “MIN” mark, immediately add coolant.

1.

2.

Scalding hot coolant and steam could be blown out under pressure, which could cause serious

injury. Never remove the coolant reservoir cap when the engine and radiator are hot.

Avoid any direct contact of the coolant to the painted body of the vehicle.

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.
