Ok so everytime I pop my hood its always hot I know it is suppose to be hot of course but I was wondering what some of you guys have done to get some of it out with out spending much money to do it. I was thinking of a cowl hood but thats like $400 also wrapping the exhaust manifold with that wrap from the store but how good it that stuff? Any ideas or pics of some stuff you guys have done? Thanks

Mine is a VM Diesel and VM diesels need to be kept cool so I decided to install a vent over the Turbo, with a 12 volt extractor fan in it.
Got a bonnet scoop of Ebay, all the way from Hong Kong, and a large 12 volt, PC case fan, rated at 38 cubic feet per min. I chose this sort of fan as it just fits amongst all the pipes and ancilaries under the hood of the TD, above the turbo, without fouling anything.
First I used a stanley knife to remove the apropriate section of sound deadaning fron the underside of the bonnet

Then I cut out a square hole with the angle grinder..... No going back now.


Bolted the heavily waterproofed fan into place

then fixed the cowl on over the fan with bathroom sealant and a bead of flexible sealant around the edge

Picked an earth up under the hood, and ran a switched live from my aux panel in the truck.
Went for a test drive, and the heat being dumped out through the vent was amazing.

I like the fan but that might be to much right now but love it. I think im ganna do the vents it looks sweet and will not be to much on the wallet or time. So 95cherokee you said you did 1 vent do you have any pics? So MyHeepis.rad what size vents did you use and were did you get them. Plus I was wondering about water getting in I know it shouldnt be that big of a problem but just wondering what you did.

A cheap mod to get some heat out is to put 1 inch spacers at the hood mounts so that the rear end sits 1 inch open when the hood is closed. 1.5$ of washers and bolts.

I only installed one, over the exhaust manifold where most of the heat is, I did not feel comfortable putting one on the other side over my distributor.
I'm not worrying about rain because the vent's are angled, there's only a little water getting in, it won't hurt anything. Sorry I don't have a cam or I'd post a pic.

Well thanks again guys Im going to work something out and get it done hopefully soon. Have any of you guys used the wrap for the exhaust manifold? I was just wondering about the pros and cons about it? Thanks
It is really good stuff. I've seen it a lot on turbo cars, it does a wonderful job of keeping the heat of the exhaust, in the exhaust.
The only con is that it is pretty expensive, like a buck a foot I think.
It's also extremely hard to wrap the mani with it in the vehicle, if you want to do a good job with it, you gotta take the mani all the way out and wrap it on your bench.
