3. COOLANT
Always refer to the chart to determine the correct cooling water to
antifreeze solution mixing ratio.
CAUTION:
1. Supplement inhibitors or additives claiming to provide
increases cooling capability that have not been specifically
approved by Isuzu are not recommended for addition to the
cooling system.
2. When supplying or replacing coolant, do not use water of
well or river, but be sure to use tap water (soft water),
distilled water or demineralized water.
3. It is strongly recommended to use Isuzu genuine engine
coolant or equivalent for addition or replacement.
4. Coolants from other brands often do not contain
anti-corrosive, and use of such products could result in
corrosion of the engine and radiator.
5. If the density of Isuzu genuine engine coolant exceeds
60%, the reduced specific heat characteristic of the coolant
could result in overheating. If the density is below 20%, the
anticorrosion characteristic may degrade. Adjust the
coolant density in the range from 20% to 60% according to
the situation.
