Abstract

A method for manufacturing a cast cylinder head for an internal combustion engine in a casting mold includes placing a sand core in a casting mold in a cavity between an upper part and a lower part of the mold to form a water chamber. Before casting, a displacement body is placed in the sand core, and the displacement body remains in the water chamber after casting.
