Car keeps overheating. I have no coolant and the heater blows out cold air. Finally the car went out and had to call tow truck. Waiting to hear cost of repair

I started to smell coolant when I would get out of my car, it never did over heat. So I took a flashlite and pointed it into the radiator resivor to light it up and it was almost empty. Dropped it off at the dealer and they called me saying my thermostat is stuck closed and I have a very small leak on the top radiator hose. Went ahead and changed the bottom radiator hose also.

Engine overheats after 30-40 minutes of use. Will go "normal" if I turn heater on full blast.

I got my head gasket changed and I believe the needle is not showing true. I have not heard the fans turn on but I know that it's getting power to it because I checked it with a Meter
