(b) Slowly pour coolant into the radiator reservoir until it reaches the FULL line.
(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 radiator inlet 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.
NOTICE:
^ 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.
(h) Press the inlet and outlet radiator hoses several times by hand to bleed air.
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.
CAUTION: Do not remove the radiator cap while the engine and radiator are still hot. Pressurized, hot engine coolant and steam
may be released and cause serious burns.
(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 above the FULL line, drain coolant so that the coolant level is between the FULL and LOW lines.
