I changed the thermostat in my 04 sentra and i believe it has become air locked. The motor will get warm and the radiator cooling fan kick on. The heater in the cabin blows ice cold while on heat. I know the thermostat is good. How do i solve this air lock problem?

Turn your heater on, with engine running, keep adding coolant as air is displaced...have the cap of radiator out...naturally do so with a cold engine..keep running your heater at max. and just keep adding coolant at radiator..after several minutes all air will be out..you will notice that bubbles will stop and coolant will look calm at top of radiator orifice..
