I have a scan tool attached to my OBDII port and can monitor my coolant temperature in my 2019 Sorento SX. I noticed that at turnpike speeds the temperature reads between 215 and 220°F. In my 2013 Sorento that reading was always steady at 185°F. I spoke with the service manager of the KIA dealership and he assured me that this was normal.
If the motor has a 185° thermostat, shouldn't the coolant temperature be at or near 185°? In stop-and-go traffic, the fans are actuated to move air across the radiator to keep the engine from overheating, but at highway speeds there is enough air flowing past the radiator to maintain the proper temperature.
Should I be concerned or is the service manager right?
