    Maybe the Coolant is not circulating properly for one reason or another.

    If there is nothing obviously wrong with the Coolant then running FORScan with the Coolant and Cylinder Head Temperatures showing, assuming that Engine has a Cylinder Head Temperature Sensor, may throw some light on things.

    I would expect the Coolant and Cylinder Head Temperatures to steadily rise within a few degrees of each other up until about 90 c with normal driving and reach 100 c or more when driven hard.

    I would expect the Coolant Temperature to slightly lag the Cylinder Head temperature.
