7. Flush the cooling system.
Pour soft water (preferably after heating moder-
ately) through the pressure cap opening. Refit
the pressure cap tightly by turning it clockwise.
Lower the cab.
Start the engine, then run the engine at a
medium range RPM until the water temperature
gauge needle points the center of the scale, and
continue running the engine for about 10 min-
utes more from that point. Stop the engine and
discharge the water. Remember that the water
is very hot.
Repeat the above procedure until the water is
free of dirt.
CAUTION
If the radiator tubing is clogged or coolant is
more contaminated than usual, have your vehi-
cle inspected at an authorized dealer.
8. Make sure the radiator drain cock and engine
drain plug are securely fitted.
9. Tilt the cab. If the vehicle is a Crew-cab model
vehicle, uncover the engine inspection opening.
10. Pour coolant (FUSO DIESEL LONGLIFE
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).
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.
