I've been doing a ton of travelling for work and when I'm home, I've been spending a lot of time getting the house ready for our little girl who is due in June and getting our rental property ready to sell. I wasn't really getting to enjoy the Jeep as much, so I decided to install one of my favorite mods from my LJ, the PSC Hood Louver. The install is pretty straight forward.Here's a before: Hosted by JeepParking.com Here's an after: Hosted by JeepParking.com The instructions that come with it are pretty thorough, but I figured I'd document the process along the way incase anyone else is interested.First thing to do is detach the hood. You do this by disconnecting the hinges first. Some people like to disconnect the hinges inside the engine bay. I did this on the hood itself. Hosted by JeepParking.com Downside to this is that you break the paint seal that was put on top of the screws and hinge, but I suppose you could seal it again somehow if you wanted to.Once you've done that part, disconnect your hood latches and the hood will lift right off. I set mine on a set of sawhorses. Hosted by JeepParking.com This project is easy as long as you have the right tools. Having a sturdy place to set the hood down is very important because you are going to be sawing into it. When I did this on my LJ, I did it with the hood on the ground. That was not very pleasurable.Next thing I did was take all the screws and paint them black. I first put them into a styrofoam block to stand them up. Hosted by JeepParking.com Then it's just a little spraypaint and they'll be good to go. Mine did get scratched up after I installed them, so I'm going to tape them off at some point and respray them.Now we go back to the hood. Start by taking off the rubber hood stops and the footman loop. Once you've done that, take the paper template that PSC provides and lay it on top of the hood. There will be two circles for the rubber stops. Align those with the ones on your hood currently and poke your rubber stoppers through them. Hosted by JeepParking.com Those two holes will align everything, so make sure your template positioning is accurate. When it comes to this project, you want to measure three times and cut once.Once everything was lined up, I taped the template on to keep it in place. I then started drilling. Hosted by JeepParking.com I opted to make many tiny drill holes along the path. They say to use a 1 inch hole saw to make the initial holes, but I was using a dremel so I didn't need that.Once I had all my holes drilled, I took the template off. Hosted by JeepParking.com Lots of tiny little holes. Time for tape. Hosted by JeepParking.com Where you see squiggley lines is where you need to make shallow cuts. Underneath those lines is the hood support frame and we don't want to cut into that. Now it's time to make some bigger cuts! I used a dremel with an attachment meant for metal. It's one of those reinforced discs. Here I am mid-cutting. Hosted by JeepParking.com For the areas that don't have any frame support underneath, I used a jigsaw. The hood ate through the dremel discs, so I wanted to use it for as little as possible. The jigsaw cut through the hood like a hot knife through butter.Once all is said and done, your hood will look like so: Hosted by JeepParking.com Definitely no turning back at this point.For some reason, I decided not to take many pictures after this point. Sorry. I will explain the process though.Next thing we want to do is put on the actual hood louver and line it up in the same way you lined up the template before by using the rubber hood stops as a guide. Once it's lined up, mark where all the holes around the edge of it are going to go.With your marks complete, take the hood louver off and use a drill to make the holes. If all goes well, everything should line up when you're done making the holes. In holes that fall in areas with frame support, I only drilled through the hood and not the frame support. If you have skinny fingers, there is enough space for you to guide a nut and washer inbetween the frame support and hood.The only areas I had issues were next to the hinge attachments. That was a pain in the butt because that area is much thicker. I ended up drilling a bigger hole than I needed to through the bottom to be able to get the nut in.Now with all your holes drilled, tape everything back up and put down some paint to provide rust protection. Since I have a black hood, I just used black paint. Make sure to do the top and bottom of the hood.Once the paint is dry, it's just a matter of putting on your hood louver and screwing things down. If your holes don't match up, don't fret. Fortunately you have a lot of space to work with and worst case scenario, you might have to use a larger washer. I did this for one of my holes unfortunately but it was easy to recover from.Here is the final product: Hosted by JeepParking.com Hosted by JeepParking.com Hosted by JeepParking.com I opted to keep the star on the hood because I like how it looks cut off like that. This mod isn't so much for keeping the engine cool, but for keeping the components in the engine bay a little cooler by letting the heat escape.I ran this mod on my LJ for a while and didn't notice any negative side effects as far as water in the engine bay. I figure that it's wide open from the bottom, so adding a few holes in the top isn't going to make much of a difference.
