I had a 16' hellcat for a couple years and I just traded it for a '21 hellcat charger redeye with 7800 miles. I noticed today that the coolant temps run higher and the fan kicks on more often. I notice way more jumping around on the Guage. Is this typical on the redeye? Do they just run hotter?

I just bought it yesterday paid 90k for this car and I have a check engine light come on. Take it to my local dealer and they tell me the catalytic converter needs replaced (covered under warranty luckily). Now I notice this temperature deal and I'm starting to wonder. It was a pilot car drove by a "dodge executive" and I'm wondering if this dude drove the crap out of it. Carfax was clean though.
The 210 is fine, but the 185 acts like a 180 Stats was installed. Factory is a 195 & recommend that. With a factory stat, your cycling temps would be around 198-200 to 210-212. The fan is cycling which is great.
Do you know if your car has any mods?
Possibly normal. RE has 797hp vs. 707hp for the Hellcat.
While you are (probably) not asking the RE engine for all its power underway there is more HP being made and thus more heat. (But maybe "stuck" with the Hellcat cooling system which accounts for the "jumping" around of the gauge.)
As long as the coolant temperature remains reasonable, and even under the most severe operating conditions the temperature at some point goes no higher, I don't think there is anything to worry about.
(Years ago when driving in 116F ambient temperature the coolant temperature climbed to 226F. This was quite a bit higher than I had seen it get up to before. At 212F the fan came on running at low speed. At 216F the fan speed was switched to high. I don't think I ever saw the coolant temperature get to 220F. At any rate while the coolant was at 226F it never went any higher. And the cooling system manifesting no signs of any issues. No leaks. No odor of antifreeze.)
While under some situations (prolonged driving in town) my 2018 Hellcat coolant temperature would climb but the fans came on at IIRC 216F and lowered the temperature and shut off IIRC at 208F. After a bit more driving the coolant temperature would climb and the process would repeat as long as I continued to drive the car in town. Occasionally in very hot weather the coolant temperature would continue to go up but at some point the fan speed would be increased and then the temperature would drop.
The car is used. So you want to be sure the coolant level is good. Not too low but don't overfill it either. You want to be sure the coolant level doesn't go down over time. IOWs the cooling system must be leak free.

Invest in a tazer. You can manually control radiator fan. Just make sure cat issue is dealt with first.
I use it to compliment my 190 Stat when not at highway speeds. Yes you can tune it but I still have warranty left.

Converter operating below efficiency threshold.
While converter problems are rare at low miles they are not immune to suffering from "infant death" and failing prematurely. They are covered by the new car warranty and in fact are warrantied for 8 years 80K miles.
CarFax is not infallible. That is not everything a car might experience that one would expect to end up being reported by CarFax is reported by CarFax.
Generally executive cars are not thrashed. The exec uses the car to drive to/from work and that's about it. Press cars are a different story.
If the previous owner drove the crap out of the car a telltale would be new tires. New brakes.
My old 2020 Durango SRT was purchased off the showroom floor with 3mi on it, I had it about 2-3 weeks and threw a code and my catalytic converter was bad from the factory. 100% warranty covered and was replaced as soon as a new one arrived.
This has happened with others, its just a bad run of cats they put on.
My SRT was fine for another 24k miles after no issues, other than I needed to sell it for my 21 Durango Hellcat! LOL
Carfax is only as good as the dealers suppling the information. I had come across a challenger hellcat that was a “clean” carfax. Upon further inspection of the car it leaked coolant. I also called the servicing dealer in Alabama and they had told me they had done a long block and super charger on it because it was in a accident. Do your research.
