Many Saturn engines have a bleeder screw at the water inlet, where the top hose goes to the engine.  Air gets trapped in the heater hoses and core.  Run the engine to operating temperature.  Slowly open the bleeder screw to let air/steam out.  Close the screw when coolant comes out.  Repeat this bleeding procedure until no more air comes out.  This will stop the overheating.
