Change coolant
 Steps to change water coolant (simplified):
1. In order to avoid burn and make sure of safety during change
of water coolant, please cool the engine temperature in
advance.
2. Loose the drain plug bolt on the water pump cover and
evacuate water coolant. Reinstall the drain plug bolt with
water having been evacuated.
3. Add new coolant from the inlet; start the engine with the full
level reached.
4. Make sure of the coolant temperature conformable to the
circulating temperature of the thermostat with the engine
started. Loose the bleed screw on the top of the thermostat;
check any air remaining in the water hose and evacuate it
prior to tightening the screw.
5. During the coolant temperature gradually increased to the
circulating temperature, some bubbles from coolant will be
observed at the inlet (residual air evacuated by the system).
6. Stop the engine and check coolant for addition in the event of
no bubble observed at the inlet and the coolant level stable.
7. Keep watch for the coolant level of the auxiliary water tank at
the first three drives with the water coolant having been
changed. Please add any water coolant up to the standard
level, if necessary.
 The volume to be replaced should be one-half of
the total capacity.
 The simplified steps could be performed during the
general minor maintenance.
 Total capacity to be replace: 0.55 liter
Concentration of coolant: 30~50%
 Steps to change water coolant (along with removal of the
cooling tube):
1. In order to avoid burn and make sure of safety during change
of water coolant, please cool the engine temperature in
advance.
2. Loose the drain plug bolt on the water pump cover and
evacuate water coolant.
3. Disconnect the water coolant connector in the vehicle’s the
lower right corner; remove the cooling tube and evacuate
residual water coolant inside; check the tube for any
deterioration (crack or curing) or replace it, if necessary.
4. Reconnect the cooling tube connector and tighten the drain
plug bolt with water coolant evacuated.
5. Add new coolant from the inlet and start the engine.
6. Make sure of the coolant temperature
conformable to the circulating
temperature of the thermostat with the
engine started. Loose the bleed screw on
the top of the thermostat; check any air
remaining in the water hose and evacuate
it prior to tightening the screw.
