Finally overheated

You didn't overheat, the computer protected the engine.

The fan shouldn’t make a difference while driving down the road, you have more air through the radiator at speed than the fan could ever produce. If it does make a difference going down the road then you have an obstruction.

You would think that, but the fins are so tightly packed that even driving the fan does a lot of work.

Engine or coolant temps?

If you have a Tazer line I do you can force cooldown mode with two button press. I keep the oil temps up most of the time and especially when towing and kick the fan on to keep the oil temps on the range I want. I also precool the engine for 10-15 mins prior to steep grades.

RPM controller also is an option.

Oil temp

I probably missed it but do you have the 3.0L or the 2.0L?

3.0

While that is hot, it's not overheating. I was very close to that going up Donner Pass in the Sierra Nevada mountains, and on some very long inclines in Utah. That's why I upgraded to the 940 Watt fan. Seems like it will help a lot.

Hello you are from Missouri and going through the Donner pass. I remember as a 5 year old coming from Sacramento thru the Donner pass and my father explaining what happened there. I have been through there a few times and love lake tahoe

except their web page says:
"Has not been tested on the 3.0 Diesel engine"

OP has an EcoD. has anyone proven it works on the EcoD?

in the meantime, were i the OP, i'd be watching the EGTs while towing uphill, and considering working on some way to get more airflow through the engine compartment and/or cooling stack.

RPM controller also is an option.

Correct. Not for 3.0. But I also mentioned es the Tazer cooldown and how I use it.

 

[zouch]

so, we agree that the Fan Controller you said "...also is an option" is not an option?

Correct. Not for 3.0.

Yes we agree. Do I owe you something for my free advice??

This topic is really old news even when it's a new post...The 3.0 EcoDiesel in the Wrangler gets REALLY hot when working for it's lunch. Overheating...runs hot...tomato/tomato, it's pure bullshit and it lays at the feet of Carlos Tavares and Stellantis. Those Rat Ba$tards could give a $hirt less about the end user, stuffed this engine in and just hoped for the best.

It's all about $$$$$$$$$$$$$$ for the stockholders, screw the end user and the employees making the product...Then he walked, and who know with how much cash, frigg'n thief. Here's a bit of info...


Carlos Tavares, the CEO of Stellantis, received a total compensation of $39.5 million in 2023. This was a 56% increase from the previous year. The compensation package included:

• Base salary: $2.16 million
• Short-term incentive: $6.26 million
• Long-term incentive: $28.3 million
• Post-retirement benefits: $2.1 million
• Fringe benefits: $686,885

The compensation package was approved by 70.2% of shareholders at the company's annual general meeting in Amsterdam. However, some investors criticized the increase, particularly as the company is cutting jobs and pursuing savings goals in the transition to electric vehicles.

I dont think all of that is relevant to what is happening. People need to understand the difference between a vehicle built to tow/haul and a vehicle that could tow. No one should assume just because some vehicle has a turbo diesel motor and is a small suv/truck means it can tow anything without thinking about it.

This past weekend I was driving up to O'hare to pick up the in-laws and passed a Toyota Prius on the turnpike pulling a small u-haul 4x8 or 5x8 trailer. Is a prius something that really should be towing? No. Can it? Yes. Most cars out there can tow some things. This is especially evident by all the cars with hitches over in Europe.

My point is just because we have a somewhat larger vehicle with a diesel motor doesnt mean we can just pull up to its max capacity, up a long grade, and expect it to work. I have been living full time in a 42' 5th wheel toy hauler that I put my Jeep inside since the end of April this year. With just our stuff in it it weighs around 14k lbs and with the Jeep in it in comes in around 20k-20.5k. I pull it with an F350 Dually with the 6.7PSD and 4.10 rear end. According to Ford, my truck, which is built to tow heavy, all day, everywhere, can pull 34,700 lbs for gooseneck/5th wheel. Since I am usually only pulling 14-20k, well below what it can handle, does that mean I can just set the cruise for 65 going through all the mountains passes in UT, CO, WY, MT, WA, CA and let it go? No. I have to constantly keep an eye on oil/coolant/trans temps to make sure I don't push it to hard. Could I set it to 60 and climb some steep grades? Sure, but the coolant gets up to 217 really quick and the cooling fans come on like a jet engine and stay running until it gets back down to ~185-190. Through this trip at almost every mountain grade up I went, I was running between 35 - 55 mph depending on the grade and length. Its just the smart thing to do. Before anyone tows you should do some research and reading about the proper ways to handle pulling a load and you won't necessarily run into a situation where you are overheating. IMO the JL and JT are not vehicle designed to tow, just ones that can.

Yeah, I did the Rubicon Trail this year. A very long drive from Missouri. I think it was around 1,800+ miles one way. Thank goodness I have adaptive cruise. Made the drive so much easier.

it doesn’t work like that in these jeeps. I’m sure willys41 will be along to explain it soon…

I sure hope he has a good explanation that defies physics. That’s how it’s worked in every other car made prior to the JL.

I'm surprised he hasn't spoken up. @Willys41.
