What is the difference between coolant and ordinary water?
1 Answers
Coolant and water have different compositions, boiling points, and freezing points. The freezing point of coolant can reach as low as -40 degrees Celsius, and it contains ethylene glycol. The boiling point of coolant is also higher than that of water, and it can prevent corrosion. Coolant has the following functions: 1. Winter antifreeze: To prevent the coolant from freezing and causing the radiator or engine block to crack when the car is parked in winter, the freezing point of the coolant should be about 10°C lower than the lowest temperature in the region, in case of sudden weather changes. 2. Anti-corrosion: Coolant should prevent corrosion of metal parts and aging of rubber components. 3. Anti-scaling: Coolant should minimize the formation of scale during circulation to avoid clogging the circulation pipes and affecting the heat dissipation function of the coolant.
