why does my truck show it running hot on 2006 Dodge Ram 1500

thermostat changed and truck still shows it is overheating. the mechanics state the temp is 210 even though it is showing hot

210 is not bad if you have a 195 thermostat. the sender unit or guage amy not be reading correctly. have your mechanic check these as it is very important that you do not run the vehicle hot.
