PERIODIC INSPECTION AND MAINTENANCE PROCEDURES

Pouring coolant

1 Make sure the drain cocks on the engine and water pumps are closed tightly.
2 Remove the expansion tank cap, and pour undiluted LLC.
Note:(a) Determine the amounts of LLC and water to be poured by using the LLC concentration chart.
(b) Regarding coolant, refer to
Coolant capacity (engine only)
Approx. 125 L [33.03 U.S.gal]
3 Pour water (soft water with minimal impurities, such as tap water) slowly to the full level.
4 Check the expansion tank and other parts for
coolant leakage.
If coolant leakage is found, repair.
5 When coolant reaches the full level, close the
expansion tank cap securely.
6 Crank the engine for about 10 seconds or less
using the starters.
Wait for about 1 minute, then repeat the above
cranking operation several times to remove air
from the water pump.
To crank the engine, shut off the fuel supply to the
engine (keep the control rack of the fuel injection
pump in the OFF position) and operate the starters.
7 Check the coolant level in the expansion tank.
Note: Coolant to be added should have the same
LLC concentration as the coolant in the
engine.
