Depends on your service writer or service manager. I've had a few warranty items covered while tuned, AGS deleted, oil cooler installed, and catch can. Never a word. But, they weren't engine failures either. They did recently warranty my DPF.

I'm at 135k miles. Engine oil is down around 30º across the board, coolant down 10-20º. Base operating temp of my oil is 167º due to the 180º oil thermostat.
Have you thought about upping your oil thermostat? On the ecoboost forum the aftermarket company supplying the oil coolers recommend running the 205 thermostat. As does the guy who has a shop that installs the coolers says they run 205 on all their builds. Their theory is the engine needs 200 degree oil to burn off deposits and moisture. Probably even more important on these complicated new diesels designed to run hot with egr and dpf filters. Sounds like a recipe for a clogged dpf. Might be different on a deleted truck but you’d still want to run it hard enough regularly to burn off the sludge.

180º oil thermostat is working perfectly for me. I've had many many oil analysis done since install and there is no moisture or any other worries.

I'd be hesitant to listen to a Ford page, they've already made one bad decision lol. I'd also find out if they have oil analysis done to back up their claims.

lol oh Ford burn 🔥 🔥. It wasn’t technically the Ford fan boys spreading this information but the actual manufacture of the oil coolers and mechanics installing them. Good to see your oil analysis are coming back good. I’m about to send my sample to black stone this week to see what break in and high 110 degree towing did to my oil. Have you had any DPF issues while running your oil cooler?

Zero dpf issues. Why would you suspect dpf issues?

If your fluids are running that much lower than normal operating temps. Is the truck trying to compensate for this? Is it running richer to get up to operating temps that it can’t achieve? Short trips are known to not be good for the dpf already and this just seems like something that could ad to the problem. I’d rather run closer to normal operating temps and have the extra cooling to keep it in check. I’m not trying to reverse engineer this thing. Not with the several thousand dollar engine killing emission system in charge. 20 years ago I wouldn’t sweat it.

No, the truck is not trying to compensate for the cooler temps. There have been no ill effects from running cooler. I have the oil analyzed at every change. Running strong and cool at 140k miles.

You sound sure of it but I’m not sold on it yet. I just went back through the thread and your earlier post said they warrantied your dpf recently. Then later you said the dpf has had zero problems. So in the same thread you claimed both. 🤷🏻‍♂️ This is why I don’t trust the internet 🧐🙃 I thought these were 2 separate peoples replies.

Anyways I hope your truck keeps running strong. I’m going to wait to tackle any major improvements before next summer. I want to replace the grille to something with better flow for now but I don’t really love the options. Maybe something new will pop up. I’m still waiting on back ordered rims though. So who the knows what this year will bring.

Well it was warrantied because 2 of the 3 studs connecting the dpf to the scr were broken. It's very common and not related to my oil cooler mod in any way. You should inquire and do your due diligence before assuming.

Do my due diligence? Is this news talk radio lol!? No one reading the thread is going to assume that when you said you had your DPF warrantied it had broken studs. Not sure why you mentioned it in the first place, because why bring it up if it’s a non issue for warranty. That was the reason you brought it up in the first place because you had it warrantied while you had your oil cooler on. So why would you even mention it if it’s something that would not be in question.

You 'assumed' it was somehow related to the oil cooler or motor.

I'm not sure the thread you saw where I brought it up, but that would be a strong indicator as to why I brought it up in the first place lol.

Are you still questioning why my DPF was replaced at 129,900 mi?

So I did my first big tow in the heat and she ran a little hot. It was low 90’s up the grades to Payson, Az. It’s the same 2 grades that would heat up my 18 eco boost coolant to as high as 248. My new truck peaked one of the grades at 240 coolant and 270 oil. This showed 3/4 on my needles so it wasn’t maxed out. My eco boost was close to maxed out and just shy of power down mode. Nice part was my Ram trans only hit 188. So no worries there. The f150’s trans would follow the engine temps eventually since it was ran off the same radiator for cooling. The downfall to that system.

This is obviously higher than I would like to see but it really only hit these temps for a short amount of time towards the top of the hills. My eco boost hit these temps much quicker than this truck. One other mention is my truck sucked down the def fluid like no other through this run that’s maybe a 70 mile run is all at that point. I was a little under a half tank. At my arrival I was surprised to only be around an 1/8 tank and buying a box of def. Averaged 9.8 mpg on the way up and 13.5 on the way back to give you an idea of the terrain in each direction.

No issues on the way back but temps were only 80’s on the evening drive back. My eco boost would heat up on the return grades as well so the Ram fully beat it there only hitting mid 220’s on the grades back. Overall I was pleased with the power and feel of the truck towing. It only felt sluggish when I was peeking my temps towards the top. I’m sure it was pulling power then, so I wasn’t surprised. No dummy lites, just the 500 miles def warning at the top of one grade.

What do the eco diesel experts think of this? Can I do better? In the middle of summer this drive will be in the low 100’s. So more heat to be stow. I’m towing at around 50-55mph through the worst part of the grades. 30’ Travel Trailer sitting around 7700#. The next tow I’ll try to drop a little speed with the extra heat. It’s a curvy grade through some of this. So no place to race through. I just try to distance myself enough from sketchy trailer drifters. Usually someone renting a travel trailer to dodge on this drive.
Just curious, which travel trailer are you pulling? We have a smaller Grand Design 21bhe and feel like it is the perfect size/weight for the trucks capabilities. I always wonder if I can push that a bit as we could always use the extra space. Would also be interested in setup, weight distribution hitch and airbags to help with handling.

Next week will be the first time we take the trailer up north (Phx to Utah) in the summer heat mid day (usually leave early morning to beat traffic and take advantage of cooler weather). Curious to see how the temps compare.

No I didn’t assume. You brought it up in this exact thread. Mentioning they warrantied your dpf while you had your oil cooler on. I’m questioning why you would bring that up in the first place if it was just for broken bolts. Either ways no worries. Nonsensical at this point.

Nice! Yeah that’s a better match for a half ton. The grand design 28 was on my radar when we got our trailer a couple years ago. My trailer is an 18 Rockwood Ultra lite 2706. GCVW 8200lbs. I have dual batteries, 2nd a/c unit and I bring 2 Honda 2200 generators unless we know we’re not running AC. We love the trailer, the main pop out is huge. Plenty of room to let our 2 little ones crawl and roam the trailer. Plus bunk beds and large shower. Oh and torsion axles! So she rides pretty nice.

I run the equalizer 4 pt hitch. It does a good job with sway and distribution. Just needs to be correctly set up. Downfall of metal on metal is it’s noisy doing tight turns like going through parking lots or campgrounds. You can get pads that make it quiet but it does take a slight hit to sway control. I’m trying them now so we’ll see. I’ve been interested in the blue ox sway pro as well and may try it just to compare someday. I don’t think I’m going to do air bags. Unless the truck looks too goofy after I do a 1 1/2 lift to the front.

I’m very curious to see how you do. It’ll be nice to compare to another eco diesel running the same area. Are you going up 17 through flag? I haven’t hit that this year. Our next trip will be soon we just haven’t set our location and time. Take her easy up the grades. The second trip I held her back a little and dropped a few degrees in hotter weather. I think 55 is max speed in these conditions on the big grades. 45-50 towards the top isn’t a bad idea to keep it in check if temps are at the threshold. I run 60-65 everywhere else.

Oh and is your truck bone stock? Smaller trailer and stock rubber, you should do a bit better than me. Anyways good luck with your journey! Look forward to hearing how she does.

Yes, going straight up the I-17 and 89 to Utah. Plans changed a bit and it looks like we will be able to leave a bit earlier than originally estimated so may not be as hot on this trip....leaving at 8:30 in the morning so I don't think it will be above 90 yet. Also just the trailer this time, usually we have 4 kayaks that in total add another 400lbs so should be fairly light load. Either way will start tracking some of those figures

Our truck is stock, though I am considering tires with some more grip for our trip to Lone Rock which I have heard is extremely soft sand. That and even at Bartlett lake, gravel is fairly loose have come close to getting stuck out there. Realize I may loose some efficiency in return.

That is a really nice size trailer. at some point we may look at a slightly larger trailer, but for now I feel like we are still considered a novice when it comes to towing.

Just reread your post, funny you mention Blue Ox and air bags. Running Blue Ox with 1000lb bars and Air Lift Air Bags. Feel like it helps with that squishy feel and the constant bouncing, though when traveling roads that are not straight like the 89 running through the Navajo reservation I don't think anything is going to help there.

Haha nice set up! That should handle nicely. Yeah there’s some fun roads to travel up north. I got the wheels off the ground at 70 mph on the 191 to Moab awhile back in a grand Cherokee. The reservation doesn’t believe in bump signs or what should have been a jump sign haha. Luckily I wasn’t trailering. Don’t worry the next much smaller dip had a bump sign… those sick sob’s!

Around town on the record 118 degree day up and down the rolling east valley highway she sat around 224 coolant, 242 oil and 186 trans.

Speed limit is 55 on these grades. I peaked 237 coolant and 264 oil. During the rolling hills before the big grades it peaked 231 and 258 @60-65 mph. +

Overall I feel better about what this truck can do now that I see it’s limits.
This info answers a couple of my questions perfectly!

I was concerned over my temps heading up the hills from the casino to Payson, as well as the dreaded canyon heading from Globe to Show Low. My temps didn't reach as high as yours, but I wasn't pulling a trailer either. What works for me is seeing your peak temps and knowing that temps like that won't grenade my truck.

Thank you for posting this, much appreciated!

No problem! Glad it could help. It’s nice knowing the cooling system keeps it in check. Those grades definitely find the short coming of any cooling system. I’m running hot enough to want it to run slightly cooler, so I just ordered a TRX style grille to try out. It’s the most open looking grille I’ve seen so it should shave some degrees off. I’ll be testing it out soon as long as it shows up later this week.

What kind of temps do you peak unloaded? I haven’t run these areas without a trailer so far.

Which aftermarket external oil cooler did you use ? Thank You
