Abstract
A cooled cast part has an exterior surface. A cooling passageway system extends from at least one inlet port to a plurality of outlet ports. The passageway system includes a first passageway to at least a first of the outlets and surrounding at least one post. The system includes a second passageway to at least a second of the outlets passing through the at least one post.
