Coolant Temperature Range While Driving.

My 2021 Cadillac 3.0 diesel is currently reflecting 219 to 224 while highway driving at 65 to 70.
When standing still at an idle it reflects 210.
What is the normal operating temperature while driving.

Does the 219 to 224 reading come from a dash gauge or other source, such as a scan tool?

It is displayed on the dash gauge.
I think this is the answer:
3.0 L diesel coolant temp
