10. Pour
COOLANT plus soft water) up to the top of the
pressure cap opening. Pour the coolant slowly
to prevent air from mixing with it.
11. Check that the coolant level in the pressure cap
opening does not go down, then fit the pressure
cap (turn it clockwise until it is tight) and press
down the fastener to lock the pressure cap in
place.
Z12450 CAUTION
If air is not completely removed from the cool-
ing system, this may lead to reduced cooling
efficiency and engine parts failure. After replac-
ing the coolant, drive the vehicle and then check
the coolant level.
12. Lower the cab.
13. Fill the reservoir tank with the coolant (FUSO
DIESEL LONGLIFE COOLANT plus soft water)
to the "FULL" line, then replace the cap.
14. Start the engine and keep it running at a speed
slightly higher than the specified idling speed to
expel air from the cooling system. When the
needle in the coolant temperature gauge
reaches approximately the center of the scale,
allow the engine to idle for 10 more minutes
then stop it.
15. When the engine has cooled, open the pressure
cap and, if the coolant level is too low, add cool-
ant until it reaches the top of the pressure cap
opening.
16. Screw the pressure cap down tightly by turning it
clockwise.
Lock the pressure cap by pressing down the fas-
tener.
17. Run the engine a few more minutes to make
sure that there are no coolant leaks.
18. Make sure that the coolant level in the reservoir
tank is in the specified range. Add coolant if nec-
essary.

7 Cleaning the intercooler and radiator
core
If the intercooler or front of the radiator core is
plugged with mud or dust, cooling efficiency will be
reduced leading to rust. Clean the radiator core at
regular intervals.
