@V50_M66 Here is a some feedback from a short trip I took

Black Td5 Thermostat, Hayden HD, Dorman Fan
82 -85 F outside temp
No heat or air running

30 to 55 Mph on the flats 188 -190
60 and above 194
Long idles in park 194 airing up my tires, sometimes 197 in drive after a while at long lights

Long steep climbs off road at low speed, 1st and second gear low range CDL engaged 206 - 208 max speedo not registering too slow
Long steep climbs off road at low speed, 1st and second gear high range 210- 212 max 5 -10 mph

After those climbs if there is a long downhill temp drops to 183- 177 inside of 2 minutes
If there is a long flat 185-188 after about 3-5 minutes at about 20-30 mph

Inline is going in in the next few days - but temps are as expected other than the 210-212 should dropped the CDL in it was a ugly uphill lots of bouncing and traction control. Also right after I had idled for 10 minutes or so airing up.
That's quite consistent with the temps that I see in mine at that ambient temperature. Sounds like my truck is doing what it's supposed to.

Coolant temps... the more you know about your operating temps the more you worry. I think that’s why LR put the “dial” with the three settings: cold, warm, cooked. Otherwise it would always read hot!
