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

I bought a 10x5 in. boat vent from West Marine, jig sawed a hole and screwed it on.

Vent - $7, nuts and bolts - $2

Total price - $9

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.

i saw a local guy where i live mold his own using fiberglass and a paintbrush in a cowl style, i think you can get all that at home depot

i forget what size they are actually.. but ebay is where i got em at! i think it was about 20 bucks all together with s&h but don't quote me.. i dont worry about water really getting in when i wash her i go around the vents as for the rainy season i think the rain just scoots over it when im moving.... the block can handle a little rain. unless i sink it than i can worry about cracking it haha

That's a pretty cool, not to mention ingenious mod.

Hows the head goin'? Done with the gasket? Tight?

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.

Just go to your local marine supply store, they will have ABS plastic boat vents for less than $10.

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.
