Make sure the thermostat is good, a stuck thermostat would make the engine over heat. To purge out the cooling system watch this video... www.youtube.com/watch?v=xeTgmdRkQtY

Test the coolant for exhaust gases. If you have the Northstar engine, they all blow head gaskets. Sooner or later. HTH. -Jim
