First time cleaning the radiators since I have owned the car (2017).
Here is what I found:

This all started because I was driving here in wonderful Utah (about 95F) and hit 236 while driving. Highway temps were around 227, driving through a neighborhood was 236. Turning the AC off/on made no difference in temps. This was during the hot part of the day, but even still I had never seen that temp before.
I have a new water pump as of 2 years ago, and the coolant was replaced with factory Por$$$$che coolant. Expansion tank/coolant system was pressure tested and passed. I also have a 180F tstat.
After cleaning the rads I have driven on the highway (around 70F) averaging 188-195 and around 199-207 while idling in a parking lot/drive through. I hit 211 while idling, but the aux fan kicks on at that temp and brings it down to 205-207ish.
Surprisingly the AC has been working great even before the cleaning, blows nice and cold even in traffic.
I am kicking myself for not taking the extra effort to add mesh under the front grill covers to prevent this in the future. I'll be adding that in the future. Been considering wrapping/repainting the front bumper at some point anyways.
What operating temps do you all run at?
