I'm sure there's a Thread on this already but I will do one for like myself the lazy and impatient peeps anyway.
1st of all, I want to give credit to stogie25 & 2005X for helping me out with this mod, by giving me quick tips and additional info. (Thanks guys! Couldnt of done it w/o you)
Seeing that my Jeep is getting ready to be Solarmax/Rhinocoated here in a couple weeks, I wanted to do my quick conversions/mods before they cover my entire jeep with the solarmax. (That way everthing is already sealed)
(should already have in the garage/if not BORROW) I had these already in my garage
*Kobalt 13-Piece Bi-Metal Hole Saw Set ($69.00 @ Lowes)
*Dremel 7-Piece Drill Bit Set ($10.00 @ Lowes)
*Drafting Circle Guide Template 46 From 1/16 - 2 3/4 ($8.00 @ Staples)
(Had already from past drafting class)
*Measuring Tape (the kind you measure your body)
*Sand Paper or Black&Decker Metal Wire attachment
*Aluminum Gutter Guard ($10.00 @ Lowes)
*Spray Paint (if needed)
This project should only cost less than $20.00
Measure 2" above curve of hood, this will be your centerline. Draw the centerline down along the hood. Double check to make sure the 2" is consistent down the line.
Measure 2" over from the Edge of hood and mark, this will be your 1st circles edge.
Using your circle template, use the hole saw size 2 1/2 to make sure your using the correct template.
Draw the Circle within your template, using that 1st circle edge mark & the centerline as your guide.
After that circle is drawn, use a 1" gap between EACH circle
Repeat the above steps for the rest of the Hole saw sizes:
2 1/4", 2", 1 3/4", 1 1/2" for both sides of Jeep, when done-double check on all your measurements.
Some would opt to sand down then mark, I wanted to use pencil on the rust instead of bare metal & sharpie. Pencil shows up better on the rust and if you had any mistakes, its easier to rub off than wipe off sharpie. After all measurements are corrected and completed. Your going to tap your centermark for your bit.
Use your dremel to start the center hole
Use 1/4 drill bit to make it bigger, seeing I was too lazy to take my hood off and drill, I attached a guide on the drill bit, to avoid going too far.
safety first! Those metal bits & pieces are a PITA so Use googles & gloves!
Next Use your Hole Saw Bits to drill, using your center hole guide. To me- I used a hole saw instead of using the Greenlee Knockout punches. 1) They are really expensive, 2) How many times are you going to use them where you can get to the other side of the metal to punch the hole. So I went with the Hole Saw Method. JUST BE CAREFUL DRILLING, BE AWARE OF WHAT IS UNDER THE HOOD
After Drilling the holes, sand them down and buff out the circles you jacked up or if you did. (I know I did)
Spray Paint if needed, Since my jeep will be rhinocoated all on the outside- I just spray painted it black for protection against new rust and moisture.
Next the aluminum gutter guards, you will just need one- Measure just to be sure
I will be spray painting mine black since my Jeep will be Fire-Engine Red, But I will wait till after she is rhinocoated then finish the final touches on the aluminum guards.
Use the dremel to cut in half.
After the aluminum guards are cut, you will be able to slide them in under the hood. Use Silicon/duct tape/clamps or whatever you want to keep them mounted.
And There you have it- fancy schmancy Hood Vents
