Thanks. It's a little over engineered :)

Now that I have painted and fitted the rad I can see there is a leak where the welding was done so I have to take it back out, get it rewelded and paint it again  >:( I will try and do a little pressure test with a foot pump first, just in case there are any more.

I finally got some wheels. 17" SSR/Desmond Koenig KG-JPN 3-piece split (not welded). One pair are 17x9s and the others are 17x8s so I am going to get some larger outer lips to make them 9.5 et22 (for the rears), I think they should fit OK.

After refitting my rad, I have noticed that it actually leaks more than it did before I got it fixed. Not impressed  >:(. There's little point going back to the guy that welded it so I will have to try and find someone else.

Made some progress with the under tray. Made a couple of brackets that I riveted to the bumper so that I can use rivnuts to secure the undertray.

Bought 6 re-amemiya wheels not really thinking about how much space they'd take up :)

It was a bit if a gamble but luckily the lips fit my KOENIGS so I can make a set of 9s and 9.5s.

Weighed the 9.5s and they come in at a little under 9.7kg. Not bad.

Some CAD for the undertray supports


And fitted this (which was a pricey extravagance)

This rad is really getting me down now.

I got project Binky on it and marked the leaks. I then applied the solder but the leak just appears to be flowing under it so I ground all the solder off and leak test it again and it appears that the leak is coming from underneath the bracket (kind of hard to explain). There is no point putting solder on it as I think it would be impossible to get a good seal all the way round.

That means that I am going to have to grind the bloody bracket off, try and find then fix the leaks, then solder a new bracket back on.

The main problem with this is that when you grind the ali it has a tendency to block the holes enough that you can see where the leaks are.

PITA!

You shouldn't grind aluminum anyway, it cloggs up the emery wheel, and can cause the wheel to violently explode when the embedded aluminum heats up and expands.
People have been killed from this.  :o

Use a disc or belt sander for aluminum, brass and other soft alloys, as they don't clog up like a stone will.

I wasn't aware that Aluminum could be soldered.  I thought it had to be welded.
Good luck finding and fixing the leak.

 :o I have never heard if that before. Thanks for the heads up.
