Does a sedan need water in its radiator?

[EloiseFitz]

A sedan does need water, but here the 'water' refers to coolant. Precautions for adding water to a car: Cannot be replaced: Ordinary water should not be used as a substitute for coolant. Color: Do not mix coolants of different colors and specifications. Brand: When using coolants from different brands, try to completely drain the original coolant from the cooling system. Lifespan: Whether the temperature is high or low, coolant should be used for the efficiency and lifespan of the cooling system. There is no theory that coolant is unnecessary in southern winters because it's not cold. Less prone to deterioration: Whether it's a new or old car, it is not advisable to casually add tap water. Tap water is prone to boiling and contains many substances that can easily form rust and scale. Coolant, on the other hand, can lower temperature, control heat, and is less prone to deterioration and chemical reactions.
