Abstract
An air door assembly for a fan shroud assembly includes a door having an upper portion, a lower portion and a hinge portion located between the upper portion and the lower portion, a frame defining an opening in the fan shroud assembly, and a hinge defining a pivotal axis pivotally coupling the hinge portion of the door to the frame. The door is adapted to pivot relative to the frame about the pivotal axis between a fully closed position and a fully open position. The upper portion of the door and the lower portion of the door may be in a substantially horizontal orientation when the door is in a fully open position. The hinge may include a pair of pivot pins extending along the pivotal axis at least partially into the opening from opposite lateral sides of the frame and a corresponding pair of at least partial sleeves at opposite lateral sides of the hinge portion of the door, the pair of pivot pins being received within the pair of at least partial sleeves to couple the door to the frame. The pair of pivot pins may be adapted to snap-fit into the pair of at least partial sleeves. The air door may transition between the closed position and the open position at a first air velocity…
