OPERATION HOOD VENT LOUVERS for 80-Series with RodLouvers.com (2 Viewers)

[GCRad1]

Visually - BIG DIFFERENCE.
Technically - seems like a big difference as the interior cab does not get as heated after running the truck then stopping. Usually on trail I would open my hood at every stop as the interior cab of the truck would get heat soaked.

Now I don't have to have everyone asking me, "whats wrong with your rig?" I can leave the hood closed and my interior does not gain heat once sitting.

Technically there was never an overheating condition.

Just that one time when I was going up 2N49 with the A/C on "FULL-BLAST" with 101-degree's summer weather outside. So yea, it got the needle creeping and I stopped to let it cool down. Previously, for the first five years owning this rig I didn't have A/C, so the 3FE is learning what this "new load" is all about, plus all the extra-metal with front and rear bumpers, steel 16" wheels and heavy tires.

I'm sure I could easily add an additional fan like what Land Cruiser Phil has shown. I'm sure I will at some point...

So how do you know it's making any difference? If you never measured beforehand, how do you know there was ever any overheating condition in the first place?

So the other day my brother was in Fontana CA at utility trailer sales. I reminded him to get me a few louver panels for my toolbox on my 18 wheeler. I spent less than 60 on 4 panels. I need them to vent my aluminum headache rack since it gets lots of condensation and makes everything rusty in there.

Anyhow, I thought these would also make a good set of louvers for the hood if cut in half. Just a though for those looking for a cheap alternative. Most dryvan trailer run these to help vent. I figure with one of them, you can cut it in half and get two short louver panels.

The Jeep JK hood louver kit from Poison Spider fits the 80 series hood almost like it was made for it. I was absolutely blown away by how close it fits! The washer nozzles even line up perfectly!!

I haven't worked up the courage to cut up a perfectly good hood yet... still have some Blue fan clutch modifying to complete before I go complete cave man on my perfectly good (albeit trail rashed) sheet metal.

Pounding Spyder shows two JK hood vents.
An ‘07-‘12 and ‘13+ kit.

Anyone know which fit? A picture would be cool to see how it looks on the 80.

Given the 13+ has two nozzles and the 07-12 has only one, I would say the 13+.

I got a set of rod's louvers that I never used if anyone is interested. Cool product, and Rod is a real guy you can talk to on the phone (!), not too pricey either.

So did anyone install the JK ‘13? Easy or hard, roughly how long did it take?

Takes as long as you want it to, just depends on how you want it to look

curious if anyone has pictures of these installed on an 80?

I haven't seen it installed, but really considering buying it. Eventually I'll receive my turbo from Wits End, and don't want heat to be an issue. I'm just wondering if I'll mess my hood up while cutting because it's Raptor lined?

You can always try the hood risers first, but no sparks needed.

Hood Risers for heat venting

I made some hood risers to help vent some of the engine bay heat. This is a nice alternative to cutting holes into your hood. Slots are added so you can install by your self a little easier. Bolts are included. I have had no issues with the hood latch. Credit to Land Cruiser Phil for...

Poison Spyder hood vents. Don't have pics of it bolted down but I think it looks decent. I wanted the miniumum water coming in with the forward facing vents so only cut out the rear facing area.

OPERATION HOOD VENT LOUVERS

For all of you who drive the 3FE UNDERpowered 80-Series, you know these rigs make a lot
of heat under the hood! My first thought was to give the rear of the hood, the hotrod look, but
actually attempting to release the heat as well! The function is the fashion. With the use of longer bolts and three thick washers later. I also removed the rubber seal on the backside to release as much air as possible.

The ADV80 has been rolling like this for at least a couple of years(?).

I purchased some Pontiac GTX vents that sat the the garage... I just didn't like the plastic and
they are covered so the amount of 'release" just seemed minimal for the amount of work it was
going to require. Yes, I could have removed the undercover, but my enthusiasm was simply curved
or curbed....

I was visiting a long time buddy who was into the whole rally thing with us and apart of our GravelCrew.
Seems as though we are all on the same wavelength as he now has a Land Rover and doing the dirt
course in slow speed too! He told me where I got his louvers made but what they had on the website
didn't quite fit what I wanted to do.

I finally got time to visit the louver maker:

I took some samples he had and started test fitting with them to see what I thought would work.
Yes, this is on backwards, but the overall shape is what I was looking at - just longer.

We take a lot of measurements that day:

A few days later I receive an email with his proposed vent panel. Yes, I wanted a LOT OF VENTING!

A few days after that I receive a package of vents!

I remove my hood and take it into the garage. Remember, I live in a townhome...
Not the most ideal working conditions, but I make it work as best as possible.

Serious time! I use the panel to make some marks so I can have some guidance for cutting!

With the bolt holes marked, I draw a line inside as this will be my cut line.

CUTTING TIME!!!

Who did you buy the kit from??

I really like the louver panel from RodLouvers! The shape of the louvers are close to the one on an FJ40 so its a nice nod to a factory option.
I took a slightly different approach with my truck, but I did consider large louver panels like the ones in this thread. I did mine a few years ago but it has definitely helped reduce the underhood temps. More important is the affect on intake and coolant temps since that is ultimately the goal with any of these mods. In my case I saw a noticeable drop in intake and coolant temps. I'll have to go back and look at my original posts to see what numbers I had. I say "noticeable" because the numbers were definitely better using my Ultragauge for the readings. But don't think of this kind of mod as a silver bullet if you're battling high coolant temps. It can help for sure, but you should also make sure your cooling system is functioning properly.

Rather than do all louvers I chose to add a somewhat large hood scoop with the idea that it would bring more fresh air into the engine compartment and raise the pressure of the air under the hood. Then I added some vents for that hot air to escape through. Before adding the scoop and vents during hot summer drives in Utah where temps can climb to 100*F or higher I could see my coolant temps climb to near 220*F on long climbs up some of the canyons. The temps could have climbed higher but if I saw then get close to 220 I would shut off the AC and turn on the heater which would bring temps back down. But turning on the heater in 100* weather isn't very comfortable. After adding the scoop and vents I can make those same drives up the long canyons on days that are 100*+ and my coolant temps typically won't get above 205*F even if I'm pushing the truck pretty hard and running the AC. A couple times I've seen it hit 208* but that's about the highest I've ever seen it since the mod. Most of the time my coolant temps in the summer will be between 187-197*, where before adding the vents and scoop they would be more like 195-210* during normal driving. So take it how you want. This is what my experience has been taking this approach with the scoop and the vents.

Since I know it will get asked, the scoop I used is from a 2007 Ford Mustang and the vents are actually fender vents from a 2009 Range Rover Sport Supercharged.

Jesus. I love it.

…totally gonna copy you now. I’ve oscillated for over a year on different types of vent solutions. I almost bought a used Dodge Viper vent to play with but decided the curvature would never work out. Your rig looks fantastic!

Thanks for the compliment. Be aware that a little shaping was required to get the scoop to fit flush to the hood. Also a little shaping to the lower section of the left side (drivers) vent so it will clear the charcoal canister.

Rod louvers also come in steel and can be welded in.
