PURPOSE: A cooling water injector is provided to neatly inject the cooling water to a radiator by forming a selective outlet closing member and to improve the cooling performance by removing the air in a cooling water circulation line. CONSTITUTION: A cooling water injector comprises a body(3) formed in a funnel shape and having an outlet in the lower portion, a locking part(5) protruded onto the lower outer circumference of the body to be fitted in a locking protrusion(2) formed on an inlet(1), and a closing member(6) formed on the bottom of the body to cut off the outflow of the cooling water by contacting to the bottom face of the inlet when the body is combined to the body via the locking part.
