Did you check to see if you have heat? Also check your bottom radiator hose when your car is warm, that should let you know if the thermostat is working or not. Also make sure theres no damage to the engine since its been overheated twice now. Open you oil cap to make sure there is no water inside.

If you have no heat with the heater on, your water pump is not working. If your lower radiator hose is cool when the engine is hot, your thermostat is stuck closed.

Keep us updated.
