Therefore, distilled water is more suitable for a car's cooling system. Impurities commonly found in tap water can cause corrosion of engine components and form deposits on cooling system components. This may cause the engine to overheat and damage system parts. To avoid these problems, special cooling liquids are used in the cooling system of cars in both winter and summer instead of regular water.
As a rule, high-quality coolants are sold in the form of concentrates. This allows you to prepare a solution with a suitable freezing temperature (-20°C, -30°C, -40°C) for specific climatic conditions. The concentrate is prepared on the basis of high-quality ethylene glycol and contains a number of additives. When diluting the concentrate, it is advisable to use only distilled water. This is necessary to ensure that the resulting coolant solution does not lose its qualities and characteristics.
Distilled water is also used to top up the battery and prepare electrolyte. An electrolyte is a solution of sulfuric acid in distilled water.
Warning. Using regular tap water to top up a serviced battery will significantly reduce its service life.
Distilled water can be prepared at home using household distillers or purchased at an auto parts store.
