How Long Can Antifreeze Be Stored?
1 Answers
Generally speaking, the shelf life of antifreeze is two years. For long-life antifreeze, the shelf life can be longer, ranging from three to five years. However, it is essential to refer to the product's manual for specific details. If the antifreeze has passed its expiration date but shows no signs of deterioration, it can still be used. Functions of Antifreeze: The main components of antifreeze are: 50% pure water, 40% methanol, and 10% other substances. Antifreeze is a 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. Methods to Determine a Lack of Antifreeze: Observe the antifreeze warning light on the dashboard. If it lights up, it is likely due to a lack of antifreeze, though it could also be caused by excessively high cylinder temperatures. Check the antifreeze reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving and add antifreeze promptly. Inspect the water level scale on the antifreeze bottle. The normal antifreeze level should be between the maximum and minimum marks. To determine if antifreeze is lacking, check the scale. If the antifreeze level is below the minimum mark, it indicates a deficiency.
