PURPOSE: A cooling fan for a vehicle is provided to reduce a noise generated by flowing air generated in rotating the cooling fan colliding with a shroud and increase ventilation capacity by separating irregularly formed air layers, thereby improving the productivity of the cooling fan. CONSTITUTION: In a cooling fan(10) for a vehicle including a plurality of rotating blades(13) radially twisted around a rotary shaft, the cooling fan includes an air guide formed at each rear end part of the rotating blades to separate flow direction of flowing air, wherein the air guide is outwardly formed in predetermined length vertical to the rear side of the rotating blade; and the air guide is detachable by forming insertion grooves at one side of the rotating blade and hooks at one side of the air guide.
