What kind of heat are we talking about? Engine water temp, engine oil temp, trans fluid temp, all of the above?From what I read, heat dissipation is an issue in both the JL and JT when it comes to the turbo engines. Both the 2.0 and diesel create a ton of heat. The design of the front clip in the JL and JT can't get enough air through to keep everything cool. That's why the JT tow rating for the diesel is lower than for the 3.6.
It comes down to getting the heat out of the engine bay. If the nose was taller with a bigger radiator like it was in generations past, there would be better airflow. But that would hurt the aerodynamics and that would hurt mileage (which is not great to begin with).
The Ram and the Grand Cherokee (when it had the 3.0 diesel) are better shaped to get the air flow you need to cool the engine. So it's less of a problem with those.
I towed a 4000+lb pontoon boat the most un-aerodynamic boat there is) for about an hour at interstate speeds (70-73mph) with no doors/roof on. Basically, a brick with holes towing a brick with tubes.
Monitored oil, coolant, and trans temps the whole way. Only ran around 10*F above normal. Temps were just past the halfway mark in the digital display, so I think ~175*F trans and ~220*F oil (don't remember coolant temp).
Now, this was back in January, but it was ~75*F.
