A cooling fan for use in an engine of an automotive vehicle includes a central hub, a plurality of blades and an annular reinforcement element. The central hub is pivotally coupled to the vehicle. The plurality of blades has distal ends spaced radially outwardly relative to the central hub. The annular reinforcement element is fixedly secured to the plurality of blades, the reinforcement element is spaced radially inwardly relative to the distal ends of the plurality of blades to prevent a build-up of ice between the fan and a shroud or housing surrounding the fan.
