1 冷却液的使用冷却液由添加剂和水组成。含40%添加剂,不仅具有-25℃的防冻性能,而且能保护整个冷却系统不受腐蚀,防止钙的沉淀,明显提高冷却液的沸点;含50%添加剂,可使防冻能力达到-35℃;含60%添加剂,则防冻能力达到-40℃。若添加剂的含量低于40%或高于60%时,不但会降低防冻能力,还会使冷却效果变坏。因此,这种长效冷却液在补充时应注意其浓度的高低。如我区冬季最低温度不低
1 The use of coolant The coolant consists of additives and water. Containing 40% additives, not only has -25 ℃ antifreeze performance, but also to protect the entire cooling system from corrosion, to prevent the precipitation of calcium, significantly improve the boiling point of the coolant; containing 50% additives, antifreeze capacity can reach -35 ℃; With 60% additives, the antifreeze ability reaches -40 ° C. If the additive content is less than 40% or more than 60%, it will not only reduce the antifreeze capacity, but also make the cooling effect worse. Therefore, this long-acting coolant in the supplement should pay attention to the level of its concentration. If my district winter minimum temperature is not low
