Diesel cooling options and ideas

[pmpmstrb]

Yea I'm curious about the thermals in this. I can get over the ugliness if it's functional.

Said the same thing about my wife.

*Deleted* Not sure how that happened, but I posted to the wrong thread......

I am looking at getting a new gladiator and read most of the 50 pages and if you did it again would you still get the diesel over the gas.

Yes

If the gas gladiator had a twin turbo v6 or even a single turbo v6 I’d switch. Natural aspersion is dead to me.

I have plenty of experience with the pentastar in a GC I just have a hard time wrappings my head around its power band and it working well in a truck

Someone on this board also offered some uncontrolled evidence that bumper, grille and some hood modifications weren't terribly effective for decreasing temps. Hard for me to imagine also.

what he did if I remember correctly was take the front clip off and drove it like that with basically very change in temps.

They have one for the JT

They market it as a "Ram Air" hood. If the Ram Air actually functions, this will hurt heat transfer rather than help it; we want as little air pressure underhood as possible to facilitate as much air movement through the radiator and charge air cooler as possible. Every bit of air that a functional hood scoop directs underhood is air that is NOT flowing through the heat exchangers. We need vents, not scoops!

I ordered the poison spyder hood vent. Cuts some pretty big holes in the hood for venting.

Next idea is going to be to try to get underhood air out of the cowl. Maybe remove the side foam pieces at the back of the cowl and vent the cowl end pieces somehow?

Also it will be winter soon so not sure its worth anymore effort beyond hood venting and water methanol.

Yes I would. I had 3 GC's w/ gas engines, mileage and towing are so much better with the diesel. Offroad is also much better, the torque is so nice.

Has anyone just thought about buying a set of RunCool louvers and installing them?

 

[pmpmstrb]

I'm thinking about just ditching the hood all together. Ratrod style.

 

[Pickles85]

I think those louvers will help get more air through the radiator. I get jeeps point of view it would be too costly to design a hood specifically for the diesel.

 

[Jeepasaurus_Rex]

I've got this set on my KJ and it lets out a ton of heat. I've got them right over the exhaust manifolds so the heat generated off them comes straight up and out.

Could definitely be worth doing, and is pretty cheap too1

If you open up the Rubicon vents and test making kick up to create a low pressure zone above the vent would increase their efficiency. The hard part would be making them out of fiberglass or 3D print them. Im really not a fan of this hood they had to put a stupid fake scoop in the center but with some small modifications I can see it working to help extract some of the heat
