My rig performs the same. Your temps are what I see under the same circumstances. In the past I've noticed coolant levels changing (down) a couple of times after changing out my coolant. My guess is that the system had a bit of air in it and needed to burp.

I don't normally run the fan on manual, but have on the last two travel segments, most of the time. Why? Because I've been worried about the coolant loss, and wanting to keep things as cool as possible.

On this trip, which started mid-August, the air conditioning was on the vast majority of the time until just a couple of weeks ago. That meant the fan was on. As we've hit cooler weather, the A/C was off a lot.

With fan override on (manual or A/C), out here in the east where there's no real mountains the coolant runs between 181 and 184.

Witn fan override is off, no matter where I am, it cycles between 189 and 197. Only exception is pulling heavy hills in heat, when probably the sky is the limit but I hold it at max 200 by gearing down/going slower as needed.
