What is everyone seeing for 'normal (not towing)' coolant and oil temps? Thanks
 
Coolant and oil temps are usually very close to each other around 225-230. I've never seen transmission temp above 174 even while towing. (albeit light around 5k towing)

I pulled my trailer for the first time this weekend (7k lbs bumper pull) and these are the temps I’d see. Seems like some thermostat would open around 222 coolant and that temp and oil temp would drop QUICK. Then it would climb to that again, and drop. Impressive to see the cooling. Same trailer with my 1500 with the 5.7 on some of the same hills I’d see 250-260 oil. I’m impressed with the cooling of the 6.4.

They did a great job on the cooling system for these 19+ trucks thats for sure
