Can You Add Water When Coolant Is Low?

[DiAvery]

In emergency situations, you can add water when the coolant is low, but it's best to use soft water, also known as distilled water. Add it in moderation, as adding too much can alter the boiling and freezing points of the coolant. The full name of coolant should be antifreeze coolant, meaning it has antifreeze properties. Antifreeze prevents the coolant from freezing in cold weather, which could otherwise crack the radiator or damage the engine block. Antifreeze isn't just for winter use; it should be used year-round. As part of regular vehicle maintenance, the engine antifreeze should be replaced every year. 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.
