How does do you run while towing??

[Duffman5001]

Hello everyone, this is my first question on this forum- so bear with me. I have searched and not found any answers so hopefully i'm not reposting.. This weekend we helped move a family friend about 300 miles away. I took our truck- an 11 6.7 crew cab with a full 9" cube box - and pulled a 22' enclosed trailer packed to the hilt. Around Butte MT there are some seriously steep long grades to climb. My truck would usually stay in 5th, sometimes pop down to 4th during the climb. My tranny would stay right under halfway on the gauge and not budge. But my engine temps would regualarly climb to 3/4 and even a touch more at times, but never entering the red. That seems pretty high to me the truck has roughly 5800 miles on it now, and at 5000 had the first maintenance done, fluids checked etc.. Outside temps were 80-90*. What do you all think? Thanks!

Sorry- the thread name was supposed to read- " How hot do you run while towing?"

The gauge has no numbers but anywhere in the normal will be safe. I wouldn't be concerned as long as it is below the red.

Yeah I don't think it's a big deal, I do wish they would have put numbers on the gauges though.. it seems that when it gets to about 3/4 a fan must kick on because it stops right there and slowly starts dropping back down..

Yu didn't say whether your truck is a Lariat or not. If it is did you check the guage mode in the information center? You should have been able to see the trannie temp and oil temp in a digital readout.

If you go into engineering test mode on the gauge cluster, then you can see a digital readout of the water temp.

Cool - how do you do that? I think I figured it out - hold down arrow and turn on key?

[Duffman5001]

Yeah mine is not a lariat, its an xl... one of our work trucks. How exactly do you check it with the engineering mode?

Really? How do i get there? Can you leave it there while driving?
Thanks

Yes. Hold the down button on the steering wheel controls while you turn the key to on. It will display "Test Mode" and then you can start it and it will stay there. There's a ton of info in there, water temp is just one. A lot of it is useless to the every day guy (like me) but still interesting.
