I like to disassemble things.
So I'm taking my time going through the car and cleaning everything up. Disassembling, cleaning, and treating if there is a hint of any oxidation or corrosion. I've gone through the top of the engine bay, the rotors and wheelwell areas, and ceramic coated the wheels and calipers. I hand rubbed the rotor hats with aluminum cleaner to nip oxidation in the bud there. I've avoided detailing the louvered hood vent for long enough so I decided to remove it and clean it up too.

To begin with, it is kind of awkward to remove, especially if you are by yourself. You can remove the vent with the rain tray still attached and then remove the tray later if you so choose. You need a 10mm socket to remove the vent bolts and a T25 Torx bit to separate the tray from the vent (whenever you decide to remove that too).

I covered the engine area so as to catch any of the fasteners if I dropped them. I also pulled the hood down a bit with some braided line at the front as my car is up in the air a bit on a lift. Note that the perimeter bolts come out easy enough but there are two push pins that stop you from tipping the front of the vent down that need to carefully be removed. I used some nylon trim removal tools to pop them from the hood. Once removed, you can lower the front of the louver down.

There are two tangs at the rear of the vent that slip into slots in the hood. Once you lower the front of the vent you can then pull the vent forward and out of the slots.

The two pins that you have to pop at the front of the vent...

And the slots in the hood that capture the tangs from the vent...

Finally off the car.

Having this off and apart gave me a great opportunity to clean everything up good. This car sat outside for a month in December in Missouri with a hold on it and then I drove it over 1,000 miles home to NY.

I've become a fan of cleaning and detailing products from Adams.

Hard to capture but the vent came out perfect. What a beautiful piece it is. I'll detail the entire assembly and then put it back in place and move on to the next area.

Remember, if you try to remove the vent, carefully pop the pins out up front or you'll likely fracture the perimeter flange in that area.

Dam... That vent looks way bigger on the floor than on the hood. :surprised:

Tob: I'm shaking my head in amazement at your post, you never let us down.

A simple project but what an excellent write-up!

For decades I have been of the belief that I've never met someone who suffers more from OCD than I but clearly, now I have. <smile>

Unlike you, I was never able to determine if mine sat outside up there or not but when I pulled the wheels and saw the rusted the axle caps, I knew that it had. (Of course I cleaned up the rust.) <chuckling>

There are numerous folks here that I would very much like to meet one day and you are certainly on that list.

On a totally unrelated note, I see you have a Scag. I do as well, just a Tiger Cup, but it's been THE best mower I've ever owned. <grin>

Alright, back to your regularly-scheduled programming. :-)

This was my worst rotor hat after applying some oxidation remover on a rag and rubbing. Not buffed yet but a shot to depict the oxidation/powder gone from the face of the aluminum hat.

This is a shot after I hand scuffed the exhaust system and then brushed some metal prep onto any welds on the system.

Today I detailed the tray and applied some ceramic coating to both sides to help move any water off of it as fast as possible.

I used the same ceramic coating on the wheels and brake calipers. I washed the wheels a couple of times, used some cleaner from Adams, and then took my time doing the barrel first and then the spoke faces. I did one wheel per day last week. The finish is truly amazing. I'll capture everything when I get the wheels back on and pull the car outside.

I did each center cap too.

Something else regarding the hood vent. The two plastic pins at the front of the vent were on my mind and I thought about a way to not have to use them again. It's clear that the factory installs them to make it simple to install the vent onto the hood on the assembly line. Slide the vent tangs into the slots at the rar of the hood opening, then raise the front of the vent up into place and drive the pins home. That allows a hands-free install of the perimeter bolts. You can see the pins in place in this shot...

IMG_6427-X3.jpg



As I mentioned earlier, these make vent removal more difficult than it needs to be and if you screw up you could potentially fracture the frame. So I pulled them off the vent and implemented what I believe to be a better solution.

I grabbed my rivnut installation tool along with some specialty rivnuts that are used for plastic or composite materials. They don't require as much force to crush as a regular rivnut. Just in case, I mixed up some high strength epoxy and swabbed the underside of the nut head that would make contact with the hood. Not to prevent them from ever coming out (they won't) but rather to eliminate the possibility for them to ever spin when trying to remove the fastener that will go inside them (a 1/4" x 20 button head screw).

IMG_6443-L.jpg



Factory plastic pins are on the left and the new hardware I'll be using on the right.

IMG_6439-XL.jpg



Installing rivnuts couldn't be easier. Normally you'd be drilling a hole but I got lucky and the two existing holes in the hood are the perfect size already. So all you do is thread them onto the tool mandrel, insert the rivnut into the hole (seating it), and then squeezing the arms together.

I'll get everything back in place tomorrow.

Thanks KB. If anything, I just want to point out the issue at the front with the plastic pins. With them gone, removing the vent is so simple anyone can do it without hesitation and quickly.

Next level care, I’m sure the car appreciates it. I’m shocked at how many people don’t even wash their cars and trucks anymore.

Everything worked perfectly.

On to the next area - bellypan.

Already. Thank God the plastic bellypan goes on before the hood pins do. But why couldn't they have dropped the other nut so I'd have a backup set?

You could see where it sat and never moved while on the 1,000 mile home drive from the dealer. Crazy.
