Depending on the destination, additives such as antifreeze may be mixed in appropriate amounts. The mixing ratio, that is, the additive concentration varies depending on the weather conditions of the destination, and is usually KO%, ``fD, ψj%, 11
Engine cooling water with different additive concentrations, such as %, is injected into the radiator depending on the respective destination. Conventionally, in order to be able to select cooling water with different additive concentrations and inject it into the radiator, separate tanks for cooling water with each additive concentration were prepared, and one of the tanks was prepared separately. The method used was to select one and inject cooling water into the radiator. However, this conventional method has the disadvantage that space is required for providing a large number of tanks and piping from these tanks, and the piping is also complicated. Furthermore, when starting the engine with water injected into the radiator, and then draining the water from the radiator and injecting cooling water with the required additive concentration, the cooling water must be injected to account for the remaining water in the radiator. There is a problem that the subsequent additive concentration changes.
