Just won on eBay. Paid $130 which was more than I had planned, but the bidding was heavy.
Good but used shape with intact drip pans and all the screws. Came from a 5.9 owner who is parting out his Jeep.
My Plans (and I am open to your ideas)
I plan to mount on my '95 ZJ approximately where the 5.9 vents normally are
The openings between the fins of the vents seem too small to let much air out, so I plan to do some grinding to open them better. I saw someone in the forum do that recently and it seemed a good idea and would love to hear from whomever did that for tips.
I plan on finding longer screws and possibly spacers to open up greater air flow between the louvers and the drip pans.
Rather than a full rectangular opening or the smaller ovals of the original install, I plan on a swiss cheese area of 1-1.5 inch holes below the louvers which should preserve some of the hood and paint integrity. Some installers have commented about paint crinkling on the hood around the large holes they cut.
Finally the paint - I am keeping the white louvers for my white hood. I probably will use a can to spray several layers of primer then Duplicor and the just expect that I will have to pepaint in a few years.
Some things if you have tips...
I put several oven thermometers around the engine compartment and was getting 180 degree air consistently after even short rides on October days. In Los Angeles area where I am, summer days I am sure have engine compartment heat hitting higher than that. Would I be better off using some kind of high temp paint rather than the duplicolor. Should I use something like BBQ paint (black) around the holes I drill? Would professional paint job or powder coat be a better way to go.
I cut the entire portion of hood out under my vents minus the holes for the screws. Made a huge difference in the amount of hot air escaping. I can drive for several hours and the hood isn't hot to the touch afterward.
I didnt use 9er vents but I just cut giant gaping holes in my hood with an angle grinder
It came out great.
No bad paint.
My hood is plenty strong, not floppy because of the new holes.
I used a cookie pan for my drip trays.
Dont over think it man, mine work great and I used gd cookie pans..
Measure 3 times, cut.
Good luck chief
This thread has me intrigued. I picked up the entire hood of a 5.9L a few months ago for $50.00
Polka, you said you cut the hood out under the tray? What do you mean? And Newfie, are you using drip trays?
If you take the vents/ trays off of a 5.9 hood you will see that there are rather smallish ovals for the heat to escape. I just cut the rest of the hood like a big rectangle similar to riots but careful to leave the stock screw holes then painted and reinstalled the vents/trays. It vents heat much better now. I was going to put pacers in but when I felt how good it was keeping the hood cool after that I didn't see a need.
