I've seen a few different charts with very similar information to this before.
I agree with the other guys, buy a programmer if you really want to monitor it. The programmers contain so many other useful settings that they are worth it.

My 2007 runs 150* most of the time. I have seen over 200* while 4x4ing in snow, but only 170* while going up some mountains in 75* temps this summer.

Mine hit 200 one time I was stuck in traffic but mostly it stays around the 150 area about 148 while cruising

Being in the florida heat mine hovers around 175-180 just cruising, thats with a slightly heavy foot haha. When i tow my boat in the interstate doing ~70 it will be about 195-200. This is a 6"lift stock 3.73 gears and 35's

I have the 4.6L, my normal is in the 150s but in the mountains or 80MPH on a hot day it goes into the low 200s. Highest I have seen it is 210 going up a mountain at high RPMs. High altitude probably has some effect on the temps, I am over a mile high most of the time. Any other 4.6L owners have similar temps? I was at a transmission shop a while back and the tech looked at my fluids and said they looked good, not burnt, so I don't think I have cooked it too much!!!

146-160 is my range, never had over 165 towing two quads (not sure the comparison on a travel trailer though).


I do have the tow package with the transmission cooler so I'm not sure if that makes a big difference and if others mentioning the 200 range have that as well?

Mine is a 4.6

I have the cooler also, I am wondering if the altitude has a bearing on temps. It is over 100 here today and I was running 180 at 65 MPH for about a 15 miles trip, engine temp was around 200. Of course the AC was on all that time.
