A cooling pump for an internal combustion engine and a cooling system including the pump. The pump is driven by an electrically-operated motor so as to rotate in a positive direction for supplying cooling water in a reservoir tank to the engine and in a reverse direction for returning the cooling water in the engine to the reservoir tank. The cooling system includes a controller that is coupled with the motor of the pump and generates a first control signal for operating the motor to rotate the pump in the reverse direction so as to return the cooling water in the engine to the reservoir tank and generates a second control signal for operating the motor to rotate the pump in the positive direction so as to supply the cooling water in the reservoir tank to the engine, on the basis of an operating condition of the engine.
