Preparation of cooling system

Coolant - Refill
Always use the coolant with the same LLC concen-
tration.
1. Make sure the coolant drain cock of engine water
pump are closed securely.
2. Remove the radiator cap, and pour in undiluted
LLC.
Note: Determine the quantities of LLC based on the
coolant capacity and the LLC concentration
chart.
For the coolant, refer to
the coolant capacity, refer to
TIONS" (12-1).
3. Pour in water (soft water with minimal impurities,
such as tap water) slowly to the full level.
Note: For absolute air bleeding, loosen the air vent
plug on the upper section of thermostat.
4. Check the radiator and other parts for coolant
leaks. Repair leakage if found.
5. When coolant reaches the full level, close the radi-
ator tank cap securely.
6. While pulling the stop lever, rotate the crankshaft
for approx. 10 seconds to turn on the starter. Stop
the operation for 1 minute, then, repeat the opera-
tion two or three times to bleed the cooling system.
Note: Prepare for the Cooling system.
