It's possible that Jeep has a lower temp for when the soft derate activates.
It's not a problem on the interstate since there's typically a passing lane on those long steep grades.
I enjoy towing through California with the 55-mph speed limit. I averaged 15 mpg one time going through the Mojave Desert towing our travel trailer.
I've seen my oil temp highest at 269 climbing that long incline near June Lake going north on 395. Ambient temp was around 100-102 degree. Surprisingly, no derating. Fortunately, i've yet to experience any derating. With 4.10s gears and 37s, i noticed it runs cooler climbing an incline doing 75mph instead of 65-70 mph.
Just an fyi for anyone reading this…
We traveled I70 last June over Vail pass fully loaded and possibly slightly over max gcvwr. Yes she slowed down considerably, but it not overheat. It seemed most vehicles were struggling and we did pass quite a few. I don't recall the temp, but it was well, under 100`.
I live in northern New Mexico, so we do a lot of towing throughout NM, AZ, UT, and CO. There are so many 18 wheelers (and large trucks in general) on the roads today, that I oftentimes find myself having to slow down for them. Our 2020 Ram EcoDiesel with 3.92 gears has no issue maintaining speed while towing, nor does it really have any issues with getting too hot. Our 2015 Ram EcoDiesel with 3.55 gears, however, is a much different story. It does get hot real quick due to the radiator/charge air cooler stacked design. I simply slow down on those mountain passes, and the truck does just fine.
My temps are hotter going through Arizona and New Mexico on I-40 than what I see going through Colorado on I-70.
just contacted them for posterity sake since they’re 45min away. I’ll try to setup a drop off of mine to see if they can make it work. I’m not the best experimental platform since I rarely tow so it will be up to y’all from there to see if this is the answer to your cooling issues.
Do you think it is at all feasible to mount behind the grill? Mounting this so low and so far forward makes me nervous for a Jeep I use to do Jeep things.I got it all mounted and plumbed today.!
Had to do a little trimming on the corner frame brackets to make room for the hoses. I welded the supplied brackets to the skid plate brackets since that was the easiest. You can still get the bolts out of the radiator and/or drop the whole thing as an assembly.
Obviously I need to cut a slot in the skid plate still, but I want to see about some expanded metal with a tighter pattern or just install a bug screen inside. I also plan to fab a box on the inside surrounding the radiator and seal it with foam so any possible vacuum behind it can be utilized for extra air volume.
Maybe......Last thing I wanted to do was add more restriction and heat to the already overtaxed OE cooling stack. Plus o would have to pull my winch and bumper to get the grill off.
The best parts of your install pics is all that other emissions BS is surprisingly missing.... Jealous a bit and good on ya!Here is my solution. It uses a Derale cooler mounted towards the rear under the bed. I am going to tap into the coolant just like BPD does, the return from the oil heat exchanger. I made a scoop for it that is easily removable. At a minimum I plan to run the scoop on long trips and definitely when towing. I am still waiting on my hose to show up so I can plumb it all in. I took the best pictures that I could. It's very difficult to do without the truck being on a lift.
Well I don’t have a diesel so I don’t know what the operating conditions are for it but for the 3.6 it turns the fan on sooner and doesn’t let the temps get so high. When does the fan on the diesel start spinning? Before the controller I would never hear mine. Now I hear it all the time.
