Under-Hood Cloth

In order to put in hood vents, I'm thinking of removing the heat-resistant cloth thing that covers the underside of the hood.

What is that for and is there any benefit/danger to removing it?

I live in an extremely hot and dry sandy desert climate, and I want the vents to help get the hot air away from the engine.

Cloth

The cloth is mostly there to reduce engine noise, it acts like a damper. Also keeps alot of heat off of the underside of the hood and saves the paint from fading so quickly. Louver your hood if you like, but leave as much cloth in tact as you can.

Thanks CJ-5, I'll follow your advice. Yes, my 93 YJ Renegade has the underhood damper cloth. There are little plastic hooks that hold it on around the edges so you could look for those to see if your Jeep had it removed.

Well, I was inspired right here on Jeepforum (http://www.jeepforum.com/forum/f12/modified-hood-82282/ - nice pics!) but was thinking about trying to lower the temperature in the engine area for some time. It's getting real hot... though there's no signs of overheating

I was thinking I'd drill a couple of holes flush to the pattern and then saw through the sheet metal; shouldn't be too hard.

I put hood vents in my hood too. They are the from an old LeBaron Turbo. They look really cool and you can see the heat just flowing out like waves in the ocean.

Anyway, I may be worng, but I remember reading somewhere that those cloths are actaully fire blankets. In case of an engine fire they are designed to fall (the plastic mounts melt off) and smothers the fire.
As people said earlier, its also help despearse heat under the hood and prevent premature paint wear. It'll be no big deal removing it, and if you feel uncomfortable about it, just cut holes through it big enough for the vents.

I'd be real quick to ditch mine if the hood itself wouldn't need a thorough cleaning afterwards. The cloth has got lots of oil on it from previous leaks and the hood has a nice dirt+oil film all over it so I'm waiting until I've got some time to play with it.
