Why thermostat won't open. Without thermostat temperature is too low with thermostat temperature is too high.

Hello - you didn't specify your vehicle model and eng size in liter. Based off what you are saying you have tried replacing your thermostat. There may be air trapped and not allowing the coolant to reach the thermostat thus it isn't opening.
