Preparation of cooling system

Coolant - Refill
1. Make sure the drain cocks on the engine are
closed firmly.
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
CATIONS" (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
cock on the upper section of thermostat when
adding water.
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 cap securely.
6. Crank the engine for about 10 seconds using a
starters.
7. Wait for about 1 minute, then repeat the above
cranking operation to remove air from the water
pump.
To crank the engine, shut off the fuel supply to the
engine and operate the starters.
When conducting the above cranking operation, also
check the items to be inspected for the lubricating
system by cranking.
8. Check the coolant level in the radiator.
9. If the engine is equipped with a reserve tank, fill the
reserve tank with coolant to the full level as well.
Note: Always use the coolant with the same LLC con-
centration.
