2001 Oldsmobile souliette over heating have change thermo and water pump flushed everything

Get the car to where it overheats, stop engine a nd make sure your fans won't start by disconnecting them. Then place your handon different spots on the radiator. If you feel any cold spots you need a new radiator as it should be the same temp all over. If it's the same temp then check for aleaking head gasket/intake. A pressure check should do that.
