What is Antifreeze?

[SanZane]

Antifreeze, fully known as antifreeze coolant, is a coolant with antifreeze properties. It prevents the coolant from freezing in cold winter conditions when the vehicle is parked, which could otherwise cause the radiator to crack or damage the engine cylinder block or head. 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 main components of antifreeze are 50% pure water, 40% methanol, and 10% other substances. It is generally categorized into three types: ethanol-water, glycerol-water, and ethylene glycol-water. How to check 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 level is below the minimum mark (MIN), do not continue driving and add antifreeze promptly. Inspect the water level markings on the antifreeze tank. The normal antifreeze level should be between the maximum and minimum marks. If it is below the minimum mark, it indicates a shortage of antifreeze.
