An object is to provide a vehicle coolant control valve having excellent response, small size and weight, and low power consumption. A coolant stop valve (vehicle coolant control valve) valve comprises a valve body for controlling the flow of a fluid, the valve body having a magnetic body; a coil spring (urging device) for moving the valve body in the closing direction; a valve seat capable of coming in contact with the valve body; and a solenoid for moving the valve body in the closing direction; wherein the valve body is moved in the opening direction by fluid pressure of a fluid discharged from a water pump (pump) during operation of the water pump (pump), against the movement force of the coil spring (urging device) in the closing direction.
