1.
Close the coolant drain cock of engine and water
pump securely.
2.
Remove the radiator cap, and add a mixture of wa-
ter and LLC of the specified concentration.
Note: Determine the quantities of LLC based on the
coolant capacity and the LLC concentration
chart.
For the coolant, refer to
"COOLANT" (6-1)
. For
the coolant capacity, refer to
"MAIN SPECIFICA-
TIONS" (12-1)
.
Note: For absolute air bleeding, loosen the air vent
plug on the upper section of thermostat.
3.
Check the radiator and other parts for coolant
leaks. Repair leakage if found.
4.
When coolant reaches the full level, close the radi-
ator cap securely.
5.
While pulling the manual stop lever, crank the en-
gine for approx 10 seconds using the starter. Stop
the operation for approx. 1 minute, then, repeat the
operation two or three times to bleed the cooling
system.
Note: Prepare for the engine oil system.
6.
Check the coolant level in the radiator.
7.
If the engine is equipped with a reserve tank, fill the
reserve tank with coolant to the "FULL" level line as
well.

Remove the radiator cap only after the engine has
cooled to room temperature. Place a waste cloth
over the cap, and loosen the cap about a half-turn to
release internal pressure. Opening the radiator cap
of coolant expansion tank while the engine is hot
causes steam and hot coolant to blow out and can
result in skin burns.
Turn the cap
about half a turn.
Always use the coolant having the same concentra-
tion.
