1. An air flow apparatus for a cooling package of a vehicle, the air flow apparatus comprising:
- a shroud defining a longitudinal axis and having a generally rectangular opening at a first end, and a generally circular opening at a second end;
a fan ring centered on the longitudinal axis and connected at a first end thereof to the second end of the shroud such that the circular opening opens to the fan ring;
the shroud and fan ring arranged to direct a flow of air through the shroud from the rectangular opening to the circular opening thereof, and through the fan ring; and
an air duct positioned below the shroud and the fan ring for routing air that has passed through the fan ring from the shroud away from the shroud and the fan ring.

Abstract
An air flow apparatus and method are provided. The apparatus includes a shroud having a first end for connection to a cooling package, and a second end for connection to a fan ring. The fan ring of the apparatus is configured to mount directly to an engine block and surround a fan of the engine block. The apparatus also includes a duct positioned below the shroud and fan ring. The duct has a first opening that opens to an engine compartment, and a second opening that opens to ambient. A flow path extends between the first and second openings and is arranged to route heated air in proximity to the shroud and fan ring to ambient.
