一、防冻液的功能 防冻液的首要功能是防止在寒冷冬季停车时冷却液结冰而胀裂散热器和冻坏发动机气缸体或盖。其主要指标是防冻液的冰点。在选择或配制防冻液时,其冰点应该比该地区最低温度低10℃左右,以确保在特殊情况下防冻液不会冻结。防沸是防冻液的另一个重要功能。其主要指标是沸点。沸点是指汽车发 First, the function of antifreeze The primary function of antifreeze is to prevent the coolant from freezing and freezing the radiator and freezing the engine cylinder block or cover during parking in cold winter. Its main indicator is the freezing point of antifreeze. When selecting or formulating an antifreeze, its freezing point should be about 10 ° C below the minimum temperature in the area to ensure that the antifreeze will not freeze under special circumstances. Anti-boiling is another important function of antifreeze. The main indicator is the boiling point. Boiling point is the car hair
