Does antifreeze have a shelf life?

This video explains the shelf life of antifreeze, a critical fluid for regulating engine temperature in vehicles. Antifreeze has a typical shelf life of 3 to 5 years in a sealed container but lasts only 1 to 2 years once opened due to exposure to air and contaminants. Factors such as storage conditions, type of antifreeze, and container seal impact its lifespan. Signs of expired antifreeze include changes in color, odor, and pH. Proper storage in cool, dry conditions and regular replacement in vehicles help ensure antifreeze remains effective in preventing engine corrosion, overheating, and freezing.
