• Adding water only reduces the concentra-
tion of the FUSO LONGLIFE COOLANT,
degrading both the additive’s antifreezing
and corrosion-preventive capacities. Any
additional coolant should contain the FUSO
LONGLIFE COOLANT at the same concen-
tration as the original coolant.
5.1 Ordinary refilling (to reservoir tank)
CAUTION
Add coolant only through the reservoir tank.
Do not open the radiator cap at the top of the
radiator to add coolant.
1. If the coolant level in the reservoir tank is
lower than the “LOW” line as a result of the
above check, remove cap from reservoir tank
and add coolant up to the “FULL” line.
2. Refit cap securely after adding coolant.
5.2 Refilling when warning lamp illumi-
nates (Adding coolant into radiator)
1. Check the water temperature gauge.
If the needle points in the red zone, the engine
has overheated. Let the engine run slightly
faster than the normal idling speed to cool down
the engine. P. 13-9
Stop the engine when the needle moves to near
the center of the scale.
If the needle is elsewhere other than in the red
zone, it indicates insufficient coolant.
Stop the engine and proceed to the next step.
2. Tilt up the cab. P. 12-6
3. Check whether coolant is leaking from the radia-
tor, radiator hose, and any other parts. Also
check the fan belt for breakage and slackness.
P. 1 2 - 5 6
4. Open the radiator cap and add coolant into
the radiator until coolant reaches the base of the
filler port.
WARNING
Make sure that the engine has cooled thor-
oughly before removing the radiator cap. Put
a cloth on the cap and hold the cap over the
cloth to slowly open the cap. Doing other-
wise is dangerous as you could be scalded
by extremely hot coolant or steam.
