12-48 Simple inspection and service
If the coolant becomes very dirty, replace it immedi-
ately regardless of the specified replacement inter-
vals.
CAUTION
• Continuing to use the coolant after the spec-
ified replacement period could damage the
engine and cooling system components due
to rusting and other problems. Replace the
coolant at the specified replacement period
intervals.
• When replacing or adding coolant, be sure to
use FUSO DIESEL LONGLIFE COOLANT or
an equivalent. Using any coolant other than
FUSO DIESEL LONGLIFE COOLANT or an
equivalent could cause corrosion and dam-
age to the radiator.
1 Recommended coolant
Use a coolant containing the FUSO DIESEL
LONGLIFE COOLANT additive and soft water in the
specified proportions.
Having both corrosion preventive and anti-freezing
properties, the additive protects the cooling system
all year around.
Replace and top off the coolant only with water con-
taining FUSO DIESEL LONGLIFE COOLANT or an
equivalent.
2 Water used with coolant
Use soft water with the properties shown in the fol-
lowing table. Do no use hard water from wells and
rivers as it is liable to form scales and cause corro-
sion.
