Also, in the radiator, a phenomenon in which hot water suddenly flows into the tube 3 through which cold water flows is caused, for example, when the engine is started in a cold region, the temperature of the engine cooling water gradually increases. Until the valve temperature is reached, the cooling water does not flow to the radiator, the temperature of the cooling water becomes high, and when the high-temperature cooling water flows into the radiator only by opening the thermostat, or
This phenomenon occurs when a so-called hunting phenomenon occurs when the thermostat repeatedly opens and closes while traveling in a cold region.
