I've changed the thermostat that was not working all this happened as in the winter time of November and December there was no heat working

So the coolant was drained out and then the tank was refilled. Did you bleed the air out or do you know how to bleed, and exactly the steps involved?

i put an external temperature gauge in it and it went into alarm and 110 c or at the red line where the alarm went on in my temperature gauge the one in the car would stay on after it run for about a half an hour idling the red light would come on in the car for over temperature I think it's the motor temperature gauge that's bad I guess

I don't think it's the bad temp gauge, but bad bleeding caused this overheat. Proof: a bad temp sensor on the engine should not cause the cabin heater having no heat, which is most of the time was caused by bad bleeding method.

Why not asking for help 6 months ago? I really think the cylinder head is damaged from all of these overheat events.
