At what water level in the car should you start adding water?
1 Answers
The coolant in the car's radiator should be added when the coolant level drops below the MIN mark. Reasons why tap water cannot replace coolant: 1. The boiling point of coolant is above 120°C, while water boils at only 100°C. Using coolant prevents your car from "overheating" in summer. 2. Using water instead of coolant can lead to scale buildup, requiring frequent changes, whereas coolant does not have this issue. 3. Water can cause some corrosion to the cooling system, while coolant contains anti-corrosion and anti-rust additives. Therefore, for the sake of your most fuel-efficient family car, never use tap water as a substitute for coolant.
