After you replaced the thermostat, there is a possibility you had an air bubble in the system. After you fill the radiator and run the engine for a bit, the air will circulate out, but the coolant level will be low, which would cause an overheating problem.

Is there any white smoke coming out of the exhaust? How is the coolant level when it overheats?

If the fan is belt driven, it will run with engine running. Just for testing, remove the thermostat, hook everything back up. With radiator cap removed, can you see coolant? If so, start the engine, can you see coolant flow? The flow should instant, without the thermostat. If no flow, check the water pump.

Maybe the radiator needs to be flushed? Does it run any cooler without the thermostat?

Oil pressure is good?
