my first time pulling a camper in the mountains this weekend and i was getting concerned with my engine temps once i started uphill the temps climbed to 210-215 degrees and stayed there. my egt's stayed around 1000-1100 degrees. should i be worried or is this normal. by the way i turned my juice box to the stock mode

 

Normal on long hard pull

 

Yep...completely normal.

The fan doesn't come on for coolant temps until 215deg. Engine designed to run at 230 without issue.

 

I dont like that high of a temperature. Put a 180 degree t-stat in from Cummins. Runs cooler now. Hopefully the transmission will like the cooler temps and last a little longer.

 

Turn the A/C on and the fan will come on. That will keep the temps down some...
