Are the hood vents on the JL Rubicon functional or only decorative?

They look to be decorative only. There are no holes in the insulation under the hood.

A lot of people modified the JK hood vents to be functional, so maybe that could be done on the JL.

From what I’ve seen the hood is decoration and sides are true vents

The stock hood vents on are purely decorative. The Nacho JEEP shown in the video below is rocking a prototype hood that does provide ventilation for heat dispersion. The gentleman in the video projects that it will become available through MOPAR parts.

Of course, even if they are purely decorative the question remains whether there is a heat problem in the first place. IIRC, Eddie’s video of his very first outing with his JL showed the fan running pretty hard at unexpected times. Has anyone else had a similar problem? If not, maybe this is all a moot point.

I think some people have done an experiment where they drain water down the vents, and it is irrigated to the back of the engine compartment.

Ha, agreed. It was literally like watching a high school vid project....from the 90s.

Both vents on the 2018 Rubicon JL/JLU are indeed functional.
The side vents are open and have little to no air flow restriction.
The hood vent is also open and fully functional. It opens to a little catch tray that is fashioned in such a way that water will channel / flow thru to the backside of the hood. Yes, the water has to flow through the hood vent and then it seeps through that hood insulation, into the channel passage way and to the backside of the hood. And yes, the hood insulation does impair air flow a bit thru the hood vent but again, that hood vent is functional.

I just opened mi e up. It was really easy. Onlt took about 30 minutes to do. There is a video on YouTube, but I did my JK too and this was much easier. The engine bay is considered by Jeep to be a "wet zone" so the little bit of water that may get in is no big deal. I didn't have a problem before in the 5 years I had my JK.

Videos?
I don't know...the production quality of the earlier videos weren't bad...I thought.

Thats the ticket! I want to do the same, what about water leaking in on top of the battery or something? Hows the positioning in relation to sensitive components.
