Coolant: Service and Repair

Coolant Replacement and Cleaning of Cooling System

Tightening torque (Unit: N.m {ft.lbs, kgf.m})

-

Using the radiator for extended periods of time without cleaning can increase chance of rust and scale formation, which may cause engine
overheating. The cooling system must be cleaned periodically.

NOTE:  Coolants containing FUSO DIESEL LONGLIFE COOLANT require replacement every two years. This replacement interval can be
extended to a maximum of six years by adding FUSO DIESEL LONGLIFE COOLANT ADDITIVE to the coolant once every year for the four years
following the first two-year limit.

1.1 Draining of coolant

-

Before draining the coolant, loosen the pressure cap to reduce the pressure in the cooling system. Remember to drain the coolant out of the
reservoir tank as well.

WARNING:
-

Drain the coolant only after it has cooled sufficiently to avoid getting scalded.

-

Opening the pressure cap while the coolant temperature is still high can cause hot coolant to spray out. Cover the pressure cap with a
cloth, and loosen it slowly to let the pressure out before opening it fully.

1.2 Cleaning procedure

-

Keep the coolant temperature at approximately 90 °C {195 °F} so that the thermostat valve remains open and the coolant continues to
circulate in the radiator.

-

For the sake of convenience you can raise the coolant temperature quickly by covering the front of the radiator with corrugated cardboard or
something similar.

-

Set the temperature adjusting lever of the heater controller at maximum so that the coolant can circulate freely in the heater piping area.

-

In cases where a great amount of rust has accumulated it often happens that as a result of cleaning the radiator starts leaking. Conduct a
thorough check for leakage after cleaning.

-

Soft water to be used should have the following properties.

CAUTION:  Do not use hard water as it causes scale and rust.
