4.1.3 Coolant
The cooling system of the natural gas engine must be filled with pure coolant, which has the
antifreeze and anti-boiling properties, can avoid freezing in cold weather or "boiling" under high
temperature and is applicable for vehicles under different temperature, which gives a special
protection for the water tank and the engine cooling chamber.
The properly selected coolant can effectively protect the engine components and extend the
service life of the engine. See Table 4-3 for more details.

Since the coolant of gas engine needs to provide
the heat exchange for the vaporizer, the freezing
point of antifreeze selected for gas engine should
be at least 10°C below the local minimum
temperature.
Notice:1) Check the coolant regularly to prevent corrosion damage. Replace the coolant if
necessary.
2) Never use water or low-grade coolant.
