[FEEDING WATER]
1. Pour tap water and the coolant through the water inlet
until the liquid level reaches the lip of the inlet.
For the mixing proportion of water and the Super
Coolant, refer to the "Table of mixing proportion of
water and undiluted coolant".
2. Loosen the air vent plug (5) of EGR cooler to vent the
air entrapped in the cooling water.
gasket without fail.
3. If cooling water is overflowing from the air vent plug,
tighten the air vent plug.
Tightening torque for the air vent plug: 27.5 N·m [2.8
kgf·m]
4. Securely attach the radiator cap (2).
5. Replenish cooling water to the specified quantity of
sub tank (6) and close the cap of sub tank (6).
6. Start the engine and after running at an idling speed
for about 3 minutes, stop the engine.
7. After the coolant is found to have been cooled, slowly
remove the radiator cap (2), and if the level has been
lowered, fill the cooling water to the lip of the radiator
water inlet.
8. Securely mount the radiator cap (2), start the engine,
and warm up the engine at an idling speed. When the
radiator is equipped with a heater, the air entrapped in
the heater circuit must be vented. Maximize the set
temperature and blower revolution speed. Then,
perform the warm-up run until the water temperature
meter indicator is stabilized at a revolution speed
around 1500 rpm or more (cooling water temperature:
approx. 75 to 90°C), and then stop the engine.
9. When the engine is cooled, the pressure inside the
radiator becomes negative, and consequently the
cooling water is poured automatically from sub tank
(6) to the radiator. After the cooling water is found to
have been cooled, slowly remove the radiator cap, and
if the level has been lowered, fill the cooling water to
the lip of the radiator water inlet. If the water level is
extremely low, check for any leakage of cooling water.
10. Securely attach the radiator cap (2).
11. Replenish cooling water to the specified quantity of
sub tank (6) and close the cap of sub tank (6).
