Yes all you need to do is remove the upper water hose and clamp and 2 bolts holding the thermostat cover in. Then pull off the cover and pry out the thermostat. You will need a new gasket when you reinstall the a new thermostat.
Its little hard to change out the thermostat in a dodge, My advice is Better go to qualified Service persons, need to spend money but for service but will give proper work completion.
