Engine Coolant - Check And Replacement - Mitsubishi FUSO FE 2006 Owner's Manual

Engine coolant – check and
Inspection intervals
Replacement intervals
If the coolant becomes very dirty, replace it immedi-
ately regardless of the specified replacement inter-
vals.
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.

3 Using coolant additive
To prevent the cooling system freezing up and mini-
mize corrosion, use FUSO DIESEL LONGLIFE
COOLANT or an equivalent. FUSO DIESEL
LONGLIFE COOLANT is an ethylene-glycol-based
antifreeze (SAE J814-C) with both anti-freeze and
anti-corrosion properties. Dilute it with soft water to
the specified concentration.
