What is the shelf life of antifreeze?
1 Answers
Antifreeze generally has a shelf life of two years. Automotive antifreeze typically operates in high-temperature environments and is prone to changes during storage. If the antifreeze is found to be expired, it should not be used further. Expired antifreeze not only loses its antifreeze properties but may also cause harm to the vehicle. The full name of antifreeze is antifreeze coolant, meaning a coolant with antifreeze functionality. It is a type of coolant containing special additives, primarily used in liquid-cooled engine cooling systems. Antifreeze offers excellent performance in preventing freezing in winter, boiling in summer, and resisting scale and corrosion year-round. Antifreeze is not only used in winter but should be used throughout the entire year.
