A shroud having speed responsive diverter means associated therewith is operatively connected at one end thereof to the opening means and mounted at the other end thereof adjacent a face of the radiator for cooling the coolant therein by communicating air toward or away from the radiator depending upon whether the fan blades are used as a blower or a suction device in particular vehicular applications.
