Assuming when you purged the cooling system. You did it with the heater on and set to max.temp?

The first video is the one to use. The only extra I do is after shutting off the engine. I let it set for a while with the hose/funnel still fitted and maybe put a fan in front of the radiator blowing air to cool off the radiator.
This allow the coolant in the clear line, or funnel to back flow into the system. When the radiator is cool to the touch, I remove the hose/funnel and replace the rubber cap.

You might want to presssurize the coolant system and see if there is a "leak down," indication a leaking head gasket. Not blown, just lost some of the coating on the 5 layered head gasket.
It could also indicated a leaking radiator cap.(easiest to fix). A radiator shop should be able to check the radiator cap for you.
Back flush the radiator for best results.

Are you losing any coolant, measured in the early AM hours? Measured in/on your overflow bottle.

If you are really loading the engine (high throttle opening and low rpm), causing the timing to go "retarded", (especially if you are using a lot of assist), you will show higher than normal coolant temperatures.

Why a CVT radiator in a manual trans Insight?
