oolant
The coolant should be anti-freezing, especially when the engine is used in the plateau
and in cold weather (below 0
℃
). It is good for the engine. The most used anti-freezer is
glycol-water, which is a mixture of glycol and water (soft water is best. If well water,
spring water or other hard water is used
，
it should be mixed with 2g tri-sodium
phosphate and a liter water in order to be softened). Selection of different
proportionality coolant should vary with the ambient temperature.
