Take rad cap off when cool & run it for a while with the heater on (not defrost) and top up coolant as needed in rad, about an inch or 2 from top of rad. Let it run until you see rad fan come on & off about 2 or 3 times at operating temperature. Then replace cap, top up return bottle to proper level, and try that. Probably still air in system. If that doesn't cure it, I'd look at faulty or incorrectly installed thermostat, which would be a trip to shop that installed it, if it were me.

the engine may have a leaking head gasket, to eliminate this possibility a reputable auto repair shop will use a device that attaches to the radiator cap it has a blue fluid in it that will change to yellow if any combustion gas is present in the cooling system passages indicating a blown head gasket. Try the alumi seal product sometimes that works.

Two things you can check: First pull your oil dipstick and make sure that the oil is clear and not cloudy or milky, if it is you have a blown head gasket. Secondly if the vehicle has an electric fan make sure that it is coming on. You can do this by starting up the vehicle and letting it warm up for 10min or so or until the guage shows that it is hot. Then look under the hood to see if the fan is turning, you may have to watch it for a few min because they will cycle on and off. If the fan doesn't come on, that is why it overheats in town because it is not getting enough airflow across the radiator. If the fan does not come on you can start troubleshooting it by checking the fuses and relays in the dash and under the hood. If the relays and fuses are good and the fan still won't come on, with the key on and engine off, carefully wiggle the wire that goes into the fan, these sometimes make bad connections, but again be careful because if that is the issue the fan will begin spinning so watch your hands and fingers.

disconnect the heat hoses going into fire wall , put hose into one with pressure and flush as it sounds like it could be bloked in the heater core,the other thing that could be the problem be the hot ,cold switch as it restricts the flow to makes the heater hoter or colder , it might need tlc or replacing as it is manaul not elec
