If the radiator cap is good, this is a very difficult problem, especially since you had the head gasket replaced. Take it back to that mechanic and ask him to check the head and tell him of the issue. He may be able to check pull the thermostat out this (sucks when it gets cold because you'll have no heat), but if it doesn't overheat them, get another one. Otherwise, something internal may be an issue.
If your replacement of the 3 thermostats and they keep getting stuck (over the past four months), it sure sounds like you installed the thermostat backwards. That will always cause an overheating problem. Rhetorical question: Did someone tell you that you had to have all that work done to fix the problem?
You should have started with a simple coolant temperature sensor replacement. That would most likely have fixed your problem. The temperature sensor might have been the cause of a thermostat error code. Sometimes, one error can cause other codes to appear, even the cat converter code.
The coolant temperature sensor tells the computer how hot/cold the engine is. The computer adjusts the fuel/air mixture based upon that temperature. You may have been running rich due to the failure of the sensor. That might have caused the cat converter error code to be set. Also, with a temp sensor error, the computer assumed the thermostat as faulty and thew that code into the mix.
yes more info is needed. and what makes you think it is actually overheating.first determine if it loses coolant and overheats, or overheats and blows the coolant out. some good points here. pressure test to locate any leaks, bleed air from system, wrong or defective new part , t-stat in backwards, does new fan operate, a lot of possibilities here. but....if it indeed overheats,the first thing to do, knowing the history, is a "block test". CHEAP,FAST, and ACCURATE. a couple ounces of blue fluid is put in a turkey-baster looking tester, the radiator level is lowered a couple inches, the tester is placed over the radiator cap opening and squeezed or pumped a few times.draw coolant vapor (no liquid) into tester. if combustion vapors or pressure is entering the cooling system,the test fliuid WILL turn green/yellow immediately, indicating a problem. head/block/gskt. again. also remove spark plugs, pressurize cooling system,then have someone crank the engine, WHILE someone else looks for coolant spraying from spark plug holes
Resurfaced gasket is not right. The head must be resurfaced, new gasket (not resurfaced) and it must be torqued to a specific number. If this is not what was done then that's the problem. What you can do easily and for free is to borrow a pressure tester and test the system for leaks. These may be external (hopefully) or internal. I am getting psychic vibes that this was a botched head gasket job. It is also possible for a head to be warped beyond the ability of surfacing to correct. Then the head must be replaced (Fords).
the thermostat is not a sensed item for the computer in most situations. the temperature sensor may have a bias to it, reading higher or lower than it should. you can run a resistance test on it cold and hot and compare the results to spec for a specific temperature. the thermostat is really only a door to the coolant, only allowing it to flow through the radiator after it is above a specific temperature.
You need to have an *inexpensive cooling system pressure test done by the dealer of the car. The test will find any external or internal cooling system leaks.

Remove the thermostat and see if it over heats, this will do not harm for a while. As if it is out and still over heats then it is not the thermostat. Is the radiator blocked.

If you new thermostat is bad, obviously you need to install a good one correctly. Is sounds like you have a bad new temperature sensor or your wiring to the sensor is bad.

The system must hold pressure or it will boil over, guaranteed. There is a leak somewhere.

start with the basic tests, the service manual, or a technician.
You could have a failed new part, or a failure in your procedure.
is it relay overheating?Put a mechanical gauge in the cooling system.You did not mention the gauge.
You probably need to get a new car. lol
You are not TELLING US THE PROBLEM....you are just telling us that you randomly replaced cooling system parts....that is not telling us anything!!!
Find a better mechanic.
Some cars need to get air bled out of the system.... thermostat in backwards....
please keep us guessing.
your car sounds like its falling apart. it might help if you told up what kind of problem your having.
