There was a thread somewhere on the net where a person did some really intense research and showed that the majority of the heat from the engine bay was concentrated to the firewall on the driver's side of a TJ. The research showed all sorts of graphs and data that this fellow compiled - pretty interesting stuff.
Anyway, with that in mind, it makes me wonder - has anybody put a vent on the side of the front? Like right below the brake master cylinder area?
Didn't the old mail Jeeps have a vent door there?

Again, my only concern is the water over the engine. I understand that some water (i.e. cleaning, the occasional puddle splash) is ok, but with the deluges we get here in North Florida coupled with the heat - I just don't want to be prematurely rusting out components in the engine compartment.

Is there anybody NOT living in the sands of the west that has vents installed in the hood that could chime in?

1. That makes sense...you've got the exhaust manifold right there, so there's going to be a ton of heat coming off of it. From what I've found, the front and sides of the block are the vital, heat-soaked areas...and most of the louver kits seem to support mounting in these locations.

2. Several of the tube fender kits have a vent in this location.

3. I think someone mentioned a plate below the louver area to help with rain problems...you could probably fab up something that drained water pretty well, and even piped it off via a hose, if you're creative enough. However, I have an idea: why doesn't someone look into having a small lip rolled in the louvers in front of each vent? This would do a lot to prevent infiltration from the surface runoff from the top sides of the vents themselves: it would be mostly redirected to the surface of the hood, and all you would have to worry about would be the raindrops that go directly through the openings themselves. The stamping can't be that much more difficult...

It's my Sirius Satelite Radio Antenna. Can't wheel without a good sound track man. I got lucky with my hood. I had a slight run in with a 5 ton truck and a brick wall. The Jeep lost that fight but I got my AEV hood out of the deal. I think all in hood and paint you would be looking at a little under a thousand dollars. I bought it for the apearance and not the heat reduction though. The two bumps on the hood look mean from the side.

The front measurments are ok I think but the rear ones I'm not sure... According to those figures they look more in a square shape than rectagle. Can someone confirm those measurements??
If you go to gen-right, they have a short and a long kit, thats prolly the short 3pc kit.

I cheaped out and went with some stainless vents from the boat store. Should be here in a couple of weeks.

Has anyone tried GenRight's Perforated Side Panels with their tube fenders? Wondering if they would vent hot air as well as louvers and reduce underhood temp?

I saw a couple posts about using header wrap on the fuel rail.... since the goal is lower under hood temps it made me wonder why no one mentioned the wrap for it's original purpose 'til I went and popped my hood. The exhaust manifold seems pretty unwrapable at first glance.

I installed it on one of my bikes and it works really well. Not that I have to worry about hood temps but no more burns when I'm going for tools I can actually hold the pipe while it's running it insulates that well. Did the install at the same time as an air/fuel meter(temporary) so that's why there are wires going into my tool bag in this pic.
