When driving my temp gauge goes up a little and stays there whether climbing a long hill in hot weather or going downhill. Goes up a little more when I turn engine off. Thermostat changed last year and temp sensor changed about 3 months ago. Gauge never gets up to 180 or 190 degrees. Ideas please.

Hello,

Check the Thermostat sounds like it is stuck open....
