How Often Should Car Antifreeze Be Topped Up?

[StCaleb]

Car antifreeze should be topped up approximately every 2 years or 40,000 kilometers. For commercial vehicles, the frequency of antifreeze replenishment should be more frequent. During routine car maintenance, it's important to monitor the antifreeze level. If the antifreeze level drops below the minimum mark, it should be replenished promptly. Antifreeze is a coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It prevents the coolant from freezing during cold winter parking, which could otherwise cause the radiator to crack or damage the engine cylinder block or head. Antifreeze offers excellent performance in preventing freezing in winter, boiling in summer, and resisting scale and corrosion throughout the year.
