c. Install the reservoir cap.

d. Press the inlet and outlet radiator hoses several times by hand, and then check the coolant level. If

the coolant level is low, add coolant.

e. Install the radiator cap.

f. Start the engine and warm it up until the thermostat opens.

HINT:

The thermostat opening timing can be confirmed by pressing the inlet radiator hose by hand, and
checking when the engine coolant starts to flow inside the hose.

g. Maintain the engine speed at 2000 to 2500 rpm.

h. Press the inlet and outlet radiator hoses several times by hand to bleed air.

NOTE:



Make sure that the radiator reservoir still has some coolant in it.



Pay attention to the needle of the water temperature meter.
Make sure that the needle does not show an abnormally high
temperature.



If there is not enough coolant, the engine may burn out or
overheat.



Immediately after starting the engine, if the radiator reservoir
does not have any coolant, perform the following: 1) stop the
engine, 2) wait until the coolant has cooled down, and 3) add
coolant until the coolant is filled to the FULL line.



Run the engine at 2000 rpm until the coolant level has
stabilized.

CAUTION:



Wear protective gloves.



Be careful as the radiator hoses are hot.



Keep your hands away from the fan.

i. Stop the engine, and wait until the engine coolant cools down to ambient temperature.

j. Check that the coolant level is between the FULL and LOW lines.

If the coolant level is below the LOW line, repeat all of the procedures above. If the coolant level is
