Since you know how to replace a sensor-buy yourself a coolant pressure tester-it will help find your problem or a bloc check. Possibilies: water pump, blowngasket, clogged Rad, collaspe hose, bad stat.
Check your dipstick for milky color and white smoke from the rear of he car.
Or disable the ignition, disconnect your upper hose from the Rad and see whether the pump is working-it should push coolant out.
