PROBLEM TO BE SOLVED: To provide a cooling water circuit for an automobile, and a method for controlling a cooling water circuit for an automobile, in which flow of water to a heater core is secured to secure heating performance in a situation where quick heating performance is demanded in cold start or the like, and quick heating performance of a water-cooled engine is secured, while restricting cost increase. SOLUTION: In a cooling water circulation circuit 11, cooling water is circulated between the water-cooled engine 1 and a radiator 2, and the heater core 3 is provided on a bypass circuit 31 provided in parallel with the radiator 2. An electric pump 4 that is flow-regulatable, and changeable between normal and reverse flow directions, is provided on the cooling water circulation circuit 11. A check valve 5 is provided on a circuit 21 on the side of the radiator 2 provided in parallel with the heater core 3 for prohibiting reversing of the flow direction of cooling water.
