An engine cooling fan shroud structure (20) for a vehicle includes a skirt (12′) defining a frame. The frame has a certain wall thickness and defines an opening (22) therein constructed and arranged to permit air to pass through the skirt. The skirt includes motor mount structure (14) supported in the opening and constructed and arranged for mounting a fan motor thereto. The frame defines passageways (18) there-through to reduce an amount of material of the skirt. A film material (28) has a wall thickness substantially less than the certain wall thickness and covers the passageways such that air may flow mainly through the opening.
