Can You Add Water to a Car's Coolant?

[MacVivienne]

You should not add water to a car's coolant. The function of coolant is to protect the engine and ensure its proper operation by circulating within the engine radiator, providing anti-freeze, anti-boil, anti-rust, and anti-corrosion effects. The characteristics of coolant are: 1. Environmentally friendly, non-toxic, non-corrosive, and pollution-free; 2. Rapid cooling through evaporation and heat absorption; 3. Fast evaporation. The steps to replace coolant are: 1. Turn off the engine and wait about 30 minutes for the coolant to cool down; 2. Use a jack to lift the vehicle; 3. Loosen the screw at the bottom of the radiator with a wrench and collect the old fluid in a waste fluid container; 4. Remove the radiator cap with a wrench, being careful not to get burned; 5. Add softened water and let the engine idle for 5 minutes to thoroughly clean the internal cooling circulation system; 6. Add new coolant up to the upper water level limit; 7. After idling for 5 minutes, observe the antifreeze reservoir's scale line and top it up if necessary.
