What is the function of car antifreeze?

[DiJake]

Antifreeze is a type of coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and resisting scale and corrosion throughout the year. The key indicators of antifreeze are its freezing point and boiling point. On the market, antifreeze is available in various specifications with freezing points such as -15°C, -25°C, -30°C, and -40°C. Generally, it is advisable to choose an antifreeze with a freezing point at least 10°C lower than the lowest temperature in your region. Methods to determine if antifreeze is low: Observe the antifreeze warning light on the dashboard. If it lights up, it is likely due to low antifreeze levels, though it could also be caused by excessively high engine temperatures. Check the antifreeze reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving and promptly add antifreeze. Inspect the fluid level markings on the antifreeze tank. The normal antifreeze level should be between the maximum and minimum marks. If the antifreeze is below the minimum mark, it indicates a shortage.
