How Long Can Antifreeze Be Stored?
1 Answers
Antifreeze can generally be stored for two years. Currently, antifreeze is an aqueous solution of ethylene glycol, which is not prone to evaporation. Therefore, as long as there is no leakage and it's just a matter of low antifreeze levels, you can top it up with distilled water—never use tap water. Antifreeze also contains various additives, so antifreeze from different manufacturers should not be mixed. The full name of antifreeze should be antifreeze coolant, meaning a coolant with antifreeze properties. It prevents the coolant from freezing in cold winter conditions, which could otherwise cause the radiator to crack or damage the engine cylinder block or head. Antifreeze is a type of coolant with special additives, primarily used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and protecting against scale and corrosion throughout the year.
