Question: My car's engine is overheating!

About 5 days ago the temperature gage was almost in the red zone and it was blowing cold air. Since then the needle moves from hot to cold every few minutes and the air is always cold. Every so often it will blow hot air and the needle will go to its normal position. 3 days ago we replaced the thermostat. We were told it was probably just an air bubble so weve been unscrewing the screw by the thermostat to let the air out. Today when we went to let the air out we noticed that the antifreeze was extremely high.
