When a vehicle radiator overheats and overflows, many people simply add water to the radiator and forget it. While adding water is a good temporary stopgap measure, you should always add antifreeze to the radiator or radiator reserve tank as soon as possible. Using water alone will eventually cause your vehicle to overeat again and offers no protection against the car engine block from freezing up in the winter. You should only use water in an emergency, and never in place of a quality antifreeze coolant.
