Temp guage not reading correct??

Did not notice anything about a new thermostat. If it is , is it the correct one ? Even a new thermostat may not be opening at the correct temperature. I believe (IIRC) it should be a 185'.
You can check it by placing it in a pan of water on stove and applying heat. Using a candy thermometer check the temperature at which it begins to open. You may possibly need to use a higher rated thermostat (190') ????
