Anyone in AZ own an ecodiesel? Does it overheat in the summer?

[armd.offroad]

I am thinking of cancelling my gas order and placing a new order for an ecodisel. Does anyone in AZ own an ecodiesel? Does it have any cooling problems during the summer months under normal driving (not towing)? I am not asking about towing anything because I have nothing to tow. I am only asking if your ecodiesel overheats during the hot summer months during regular driving in arizona and I am also curious if it overheats while driving up the steep grades to Flagstaff (again, not towing anything) during the summer months (July-September).

It derated once when new after i stopped to eat lunch, i suspect it was a heat soak issue. Now when filling up fuel in the summer after a highway run, I leave the truck idling to circulate coolant and keep heat soak at bay, i also let it idle for a while before i shut down for a quick stop after a highway run.

I also watch my temps and try to not keep the hammer down and in boost for long periods of time. Full boost will make temps grow quickly.

I love the truck and it works well for what I need, handles the i-17 just fine, but I am also not towing a big trailer just a open trailer and dirtbike.

My advise to you, if you are not patient, don't like to screw with stuff, monitor stuff, take matters into your own hands, or are not mechanically savvy or don't have a second back up car, DON'T GET A EcoD JT. The odds are it may have a issue and leave you hanging with no ride. You will get frustrated and loose patients and regret your choice. There are folks like that here who whine and cry and post how everything is so bad and demand results...bla bla bla.....


I use mine for long trips and rarely DD it, the EcoD is not really a daily driver (DD) car, it likes to streech it's legs and eat miles.

Thank you for your reply as I did find it insightful. It would be my daily driver and my main vehicle so it needs to be reliable.

I would stick with the gasser and regear it for your use case.

My DD is a 2001 civic to give some insight.

There is no way a production vehicle in 2022 will overheat under normal conditions. These trucks have been tested in all sorts of conditions. They'd never get homologated. I think this forum is really blowing things out of proportion. Overheating with normal driving, there is no way.
When I was towing in very MILD temps, 40s-60s, the oil temperature did increase above 225. Was about 235F or so and I was gunning it, 75mph almost everywhere plus a section of stop and go, gunning from lights. This was not overheating or anything. There is no way it will overheat in normal conditions. This is just straight BS now.

are you talking gas or diesel?

You can get a diesel JT to derate not over heat if you keep your foot to the floor on long grades and make the boost work at full for extended time. Most commonly when you have a good load behind you. I am yet to derate with no load. We have plenty of extended grades out west to work a engine. The I-17 referenced is one of the roads OEMs use as a stress test for R&D btw.

I live in Tempe and have a 2021 Rubicon EcoDiesel. If I am not towing anything it is usually fine. If I haul butt up to Payson it starts to warm up pretty good but does not overheat.

If I am towing my 5,300 pound boat to Bartlett from Tempe it will get HOT and derate the power, especially on the return trip back home. If I do this trip in April it will go the speed limit no problem. If I do it in August in 120 degrees it will derate the power on the way home and go 35 instead 55.

When the EcoDs derate, what kind of power loss are you looking at? Is it pretty much, limp to a safe spot and cool off for a bit?

The only way I can explain it is that it just seems like it is governed and won't accelerate up hill past a certain MPH no matter what I do. It still feels powerful up to that MPH, but won't do anymore. Normally, it will accelerate and keep on accelerating until I lift.

BTW, when I am going up a steep hill on the highway I can go as fast as I want and pass no problem. I have a buddy that has a gasser Gladiator and he definitely has trouble passing on long, steep grades.

I find this whole discussion on the diesels derating somewhat ridiculous. Especially in the hot summers of Arizona.

I currenty own a JTRD. I live in N. Scottsdale.

Long time ago I had a Ram 1/2 ton 4X4 that I used to tow a medium sized boat to Lake Powell. What a joke. With temps out side in the triple digits .... the truck would derate, over heat to a point that I had to turn off the A/C just to make it. A GAS truck. I would assume that ALL vehicles towing a large load in 115 degrees up hills with the A/C going is going to eventually derate.

Now. I did sell that truck and buy a brand new F350 Turbodiesel. That truck NEVER derated. It was a tow monster.

Now the JTRD. Everyone knows that the cooling capacity is constrained due to the front, narrow engine compartment. I did not buy the JTRD to TOW. I bought it to hauls some things. Go north and have some fun at the trails.

I've driven to Tucson many times. During the heat of the summers. Never derated. I've sat in heavy traffic with the A/C going. Never derated. The truck is fine for "normal" use. If you choose to tow heavy trailers/boats. Up hill. Pedal floored. A/C going. It's going to derate lol.

It's a Jeep. Not a tow vehicle.

This is a great post. I totally agree. This is not some heavy duty tow vehicle. It's a medium sized light truck. Light duty. Towing bikes, smaller boats, snowmobiles, that kind of stuff. The engine has enough power to tow pretty much anything but is constrained by the cooling system/front fascia.
An owner will never have issues in normal driving conditions.

I would be much more concerned with the Gladiator's brakes while towing 6000lbs.

Well, I wholeheartedly disagree with you... Any vehicle should be able to tow within its tow rating in not just ideal conditions. I previously had a 2012 Ram 1500 with a 5.7L in it. It could tow my same boat without any problems on any day. I didn't buy my Gladiator specifically to tow anything, but I did buy it with the idea that it could tow my boat. I even went out and weighed my boat and trailer to make sure that I was well within the specifications. My Gladiator is my daily-driver and I like to manage my finances in a way where I invest my extra money and not buy a second truck just for something that I do less than 10% of the time.

all I ask is that any vehicle I buy be able to do what it says it can...

I don’t have much of a problem with over heating up here. I plan on snow birding down in the Nevada and Arizona desert this fall and winter. So to avoid over heating problems I installed S & B air scoops on the hood. They were pretty easy to install.

I saw those and was going to try that myself... I wonder if they will come out with a Cold Air Intake system for the diesel like they do with the gasser.
