Can You Add Purified Water If the Coolant Is Insufficient in Summer?

[StEleanor]

In summer, you can add purified water if the coolant is insufficient. Main Components: The primary components of antifreeze are ethylene glycol and water. The water here refers to purified or distilled water, not mineral water, as mineral water contains minerals that, compared to purified or distilled water, have impurities that cannot evaporate. Precautions: If the antifreeze is insufficient, you can add purified or distilled water, but never add mineral water. Not only will it increase the freezing point of the antifreeze, but the minerals in the mineral water can also react chemically with the components of the antifreeze, affecting its functionality. Antifreeze prevents the coolant from freezing in cold winter conditions when the vehicle is parked, thus avoiding the risk of cracking the radiator or damaging the engine block. Its full name is antifreeze coolant.
