Data Point….
102F outside temp, A/C set at 68F, stop and go traffic on the I405 (or as I call it, the 4 or 5mph freeway) for 25 minutes after cruzing at 75mph for about 30 minutes.
Coolant 190F
Oil 185F
Trans 180F
My Mode, Z51, track fill on DCT, all fans running.

This car definitely has strong cooling capacity; greatly improved vs. the C7!
My car holds rock solid engine/oil/DCT temps in the 170's even in triple-digit ambient temps (hottest so far that I can recall is 109°F).
For further info, I do have Scrape Armor radiator guards, ceramic coated headers & cats, some engine bay DEI heat shielding, and added a bottle of Redline WaterWetter to the cooling system.

I was just thinking of Heat Soak. it seems there is none in the vett, doesn't matter how many times i get on it in this south Florida heat ,, it feels a strong as the initial start-up .. they sure did a great job keeping her cool

Mine has a strange quirk related to cooling. If I drive like a “granny” around town for several days, the operating coolant temp starts creeping up to 190° or more. Not really too high, just a strange trend. I found that if I take it out to a back road and air it out, it comes back down for a couple of days.
Yesterday, I took a two hour road trip. On the way out, it was in the mid 90s and the temp wandered between 187° and 192° at a 75 mph cruise. On the way back, at 102 degrees outside, it started doing the same thing. I detoured onto a back road and redlined a few gears from a rolling start a couple of times. After that, it stabilized to an almost constant 185° for the rest of the trip. 🤷🏻♂️
Uptake, it doesn’t like being driven like a “granny”.
