Answers :

Are you putting the thermostat in correctly? It it will not work backwards.

And to confirm that there isn't a different problem, take the thermostat out all together and see if it overheats.

Engine not fully warming up is not usually caused by the thermostat. Stats usually fail closed, not open.

You will want to check the water temperature sending unit or gauge after verify the water temperature with an external calibrated thermometer. You can attach and insulate the external thermometer to the housing where thermostat is located.
