Topic: Hood louvers

[Jeffy]

Some XJ owners put a small electic extractor fan right over the engine.  One local jeeper put one on his YJ after swapping in a V8.  It helped a lot with the cooling, very likely more than louvers.

XJ's especially the earlier ones have marginal cooling from the factory.  It shouldn't really be an issue with a YJ though.  Add some tube fenders and you shouldn't have any worries since there are no inner wheel wells.

Add a 4 cyclinder and you can cut the Heat  by a 1/3

I went this route. I didn't have a overheating issue.  I was bored and wanted a easy project.
I picked up a 2 X 4 piece of the 1/8 inch holed steel for $7.00. I used some double sided tape to hold it on.

I get the Buick comment alot! When you stand back a few feet they look like stickers.

I used a jig saw to cut my tail lights

3M foam tape?

Those MTR's are really chewed up.

BTW: what rocker guards are those? DIY?

It is 3M tape. I got it at Lowes. It's super sticky! I guess it does have a foam center. Maybe 1/16 thick 1 inch wide.

The MT/R's I got used. They were already siped. After running them a few years I grooved them. It's hard to see in that PIC. I sold the tires and wheels when I went to 37's. Which I bought used. I grooved them too. I don't have a PIC yet. I like the way they hook up!

Rockers are some Blem Genright. They are just down the street from me. I did have some homebrew ones on before that though.

mmm muddy water cooling system...

Not like the inner fenders are going to keep the engine that much cleaner.

Well, just thought I'd let everyone know I ended up getting the Pontiac louvers (like the ones in the article Moz posted).  I'll get some pictures after I install them...

my 79CJ with the 401 HiPerf Turbo charged motor used to create a lot of heat..  I took it to a hot rodder friend that had a louver machine.. he punched louvers in the back edge of the hood to let the heat accumulated out.. I had the hood all repainted.. looks much better than those bolt in units..  classier for sure..  I put pans under them for the drain off so the water didn't dump on my engine..

i have seen that article before and i like that someone did that good of research before a mod that most would just stick where ever looked the best,  on the other side i don't think with the e fan and a four cylinder you have much to gain in temp drop considered that combo creates a massive hole in the front anyway but i guess as far as heat escape it may help some, but i would just brake them anyway considering i walk across my hood when in deep mud and have to hook up or operate my winch

I would think it would help quite a bit, as when I open the hood, I can feel the heat coming out.  Also, when the fan kicks in, I can feel the hot air coming out from UNDER the Jeep...  I have yet to install them (same with the Safari Snorkel), though, so I have no idea if they will help or not.

Post pics when you get them installed. I've been thinking of doing this for some time. Maybe when the temps get a bit warmer (low single digits coming this week) I'll head over to the scrap yard and look for a set myself.
