This patent describes a vehicle engine cooling fan and shrouding assembly for forcing cooling air through a radiator in which engine coolant is circulated comprising support means adjacent to the radiator, a fan shroud and mounting shell operatively secured to the support means adjacent to the radiator. The shell has a peripheral forwardly extending wall portion to provide an intake for air flowing through the radiator. The shell further has a generally cylindrical and rearwardly extending portion to provide a reduced dimensioned air ejector for the shell, spoke means extending inwardly from the air ejector, a fan drive motor supported by the spoke means extending axially into the shell, the motor having a rotatable output shaft extending outwardly therefrom toward the radiator and having a terminal end portion, and engine cooling fan operatively driven by the drive motor and rotatably mounted in the shell.
