It may not be a 6% grade I was trying to find out, it is a long steady grade, it's on I70 west of Frederick Maryland I think it's Braddock Mtn, there is a lookout at the top

This is only about a 5 mile grade, I saw some issues with f150 radiators and wandered if this was also a issue on the 6.7


i have had plenty of over heating issues. Trans, engine temp both reaching 240s. Taken it to the dealer and they dont find anything. They recommend to do a full ****** and add and extra fan to cool the trans.

Has anybody tried the MPD oil cooler kit to help with the high engine temps these motors are seeing when towing? I had the BPD 1/2 oil kit on my 6.4.

Honestly I think it may be a radiator problem, I saw a video of a guy with a ecoboost f150 towing a small camper at around it's towing weight limit, it was getting to 230 or 240 on f!at road, dealer replaced radiator and he reported temps back in the 215 range

did you put in towing mode or just towed it as is? sounds to me like you did the latter, i towed my 24 foot trailer from Great Mills to manassas and didnt have any issues at all, the fact that your truck was in 6th leads me to believe you didnt push the tow button, as soon as i hit a hill my truck would drop to fifth on its own, and my trailer is no where near 12k

There is a recall on this issue. Mine did this when towing, then did it sitting in traffic. There is a "clutch" in the radiator that is bad in the 17's. My dealer took it in and replaced it. I haven't had any issues since. If they give you crap about it, let me know and I will find out exactly what the part was on it. Good luck with it.
