| | Poor little 02 has been sitting in the garage for almost a year now waiting for a new cooling system and it's finally close to completion. It was hard to find a radiator in the scirrocco size but thx to Canadamatt, I found an AFCO unit that fit.. umm.. with a little massaging. It has a much thicker, double-row, aluminum core. I'm also adding an expansion tank that will feed into the H2O pump and plumb a bleed line to the top radiator hose. Hopefully, this will keep the air in the expansion tank and not in the hoses near the temp sensor.
First off, the core is so much thicker that I had to cut the two vertical hood hinge supports near the bottom and weld in reliefs so that the bottom of the rad could be moved away from the crank pulley. Since they don't really support much anymore, I drilled some holes in them to maybe help in air flow to the core. You can see the reliefs that I welded in below the second hole down.
Then I welded in some lower mounts out of box steel and flat stock. Readers have failed to make donations to my paypal account and therefore, I have no gas/regulator for my MIG. My welds look like crap because of you. I used some rubber isolation mounts here, but you can't really see them in the pic. I used Zero-Rust to seal.. I like it cuz it brushes on and I'm lazy but still want to party.
The top mounts (just comforting huggers really) were just cut, bend, drill, grind, paint, and apply weather stripping affairs.
..as you can see, I need to make new hood pinnings somehow. That'll leave two, cool, scar-like holes in my FRP hood but it'll allow me to move to captured-style hood pins which I should have done in the first place.
The bottom tube on the rad posed a problem since it was feeding directly into.. somewhere it shouldn't be. So, a great fabricator friend of mine waved his magic wand over it and viola! 90deg bend right out the gate! For this I am grateful, so go buy his shit! http://www.battleversion.com/
The expansion tank needs to be the high point of the system to collect air so I mounted it as high as possible without having the convenience of fillling it without removing the hood. I tapped out the bottom to take a larger elbow that way it doesn't take an hour to fill the system. No, that's not the hose I'm going to use for the bleed line.
Now, I'm just working on getting new plumbing ordered without contributing too much to the 'extras' bin. I'll be back.
