回路。In the middle of the main cooling water passage where cooling water is circulated between the engine and the radiator by a water pump, when the cooling water temperature is below a predetermined temperature, the main cooling water passage is closed to prevent the cooling water from flowing to the radiator. In a cooling circuit for a water-cooled engine, the heater cooling water passage has a downstream end connected to a main cooling water passage between the radiator and the suction side of the water pump. A check valve is provided in the main cooling water passage closer to the radiator than the downstream end opening of the main cooling water passage, which prevents the cooling water in the main cooling water passage from flowing toward the radiator when the thermostat is closed. cooling circuit for a water-cooled engine.
