Do you have t he northstar enige in her? Have you over heated really bad, becuase the Northstar has a failsafe on the engine, it should go into four cylinder mode if it over heats, running 4 cylinders, and pumping air in the other 4, to keep you from blowing the head gasket, I would start with the basics, how long has it been since you changed the radiator cap, if its bad, the system is not under the correct pressure, it could be your thermostat, or water pump, is your engine louder or do you hear a squeel or squeak, are you leaking any coolent anywhere, I need more information from ya, I had a 1992 STS but it had the 4.9 L pushroad v-8, went through 2 water pumps in her, loved that car!

Northstar engines have a nasty habit of pulling out the head bolts which causes head gasket leaks and overheating. The fix is new aftermarket head bolts which is an expensive repair.
