What is the shelf life of antifreeze?

[StAlejandro]

Vehicle antifreeze generally needs to be replaced every 2 years or 40,000 kilometers. This is only a reference period. For commercial vehicles with longer mileage, the replacement cycle is shorter. Since the driving conditions of each vehicle are different, the replacement should be selected based on actual usage. Check the antifreeze usage. If the antifreeze is insufficient, replenish it promptly. If suspended matter, sediment, deterioration, or discoloration is found in the antifreeze, replace it immediately and clean the system. Types of antifreeze: Antifreeze is generally divided into three types: ethanol-water type, glycerol-water type, and ethylene glycol-water type. How to choose antifreeze: The basic indicators of antifreeze are the freezing point and boiling point. The freezing points of antifreeze on the market include -15°C, -25°C, -30°C, -40°C, and other specifications. Generally, it is advisable to choose one that is at least 10°C lower than the lowest temperature in your region. Functions of antifreeze: Antifreeze is non-corrosive. It is a coolant containing special additives, mainly used in liquid-cooled engine cooling systems. Antifreeze has excellent properties such as preventing freezing in winter, preventing boiling in summer, and preventing scale and corrosion throughout the year.
