Coolant temp a steady 105 Deg?

[laketahoequattro]

So when I re did my cam belt 200 miles ago I replaced everything cam belt related to also include a new thermostat. I hope I did not bite myself by purchasing a Mahle Behr Thermostat (supposedly 82 degrees C) over an OEM one.

Using the recirculate and Up button on the Hvac I have been monitoring my coolant temps. The temp will rise to 105 - 110 degrees while on the freeway and then settle back down to 99 - 101 degrees while at idle. I have never seen the temps get over 112 degrees.

I know this is way too hot, it is supposed to sit around 93 degrees. All I can think is that it is a thermostat, clog, or air bubble in the air system. I do not think it is a sensor issue. Heat blows fine thru the hvac system, and there are no codes in the hvac.

Any ideas? Thanks in advance..
