Coolant
The recommended mixing ratio allows coolant to prevent corrosion of
the engine efficiently and to maintain the best engine performance for
a long period. Using contaminated water or unspecified antifreeze or
additives may cause critical faults in the cooler.
General Information
The coolant plays an important role in the prevention of overheating and freezing of the
engine. However, if the engine is used for a long period, the performance of antifreeze and
anticorrosion of the coolant degrades. Maintain the condition of the coolant through daily
inspections and periodic replacements. The mixing ratio for the engine coolant is 40 %
antifreeze and 3~5 % additives (DCA4) to prevent corrosion. For the water in the coolant,
use clean tap water. Periodically check coolant to maintain the concentration of antifreeze
and additives (Refer to Table 5-1).
