Does a car's radiator need water?

[DiKimberly]

Antifreeze should be added. Precautions for adding antifreeze to a car: 1. No substitution: Do not use ordinary water as a substitute for antifreeze. 2. Color: Do not mix antifreeze of different colors and specifications. 3. Brand: When using antifreeze of different brands, try to drain the original antifreeze in the cooling system completely. 4. Lifespan: Regardless of whether the temperature is high or low, antifreeze should be used for the efficiency and lifespan of the cooling system. There is no theory that antifreeze is unnecessary in the south because winters are not cold. 5. Resistance to deterioration: Whether it's a new or old car, it is not recommended to add tap water casually. Tap water is prone to boiling and contains many substances that can easily cause rust and scale. Antifreeze can lower the temperature, control the temperature, and is less likely to deteriorate or undergo chemical reactions.
