A blowtorch, soft wire brush, plumbers solder and flux.

Use a brass wire brush in a drill or by hand and thoroughly clean the area of the split to remove all the black coating, heat it up with the blowtorch, dip the end of the solder into the flux paste and melt the solder with the blowtorch along the split.

If the split is over 1mm wide, you can solder a strip of copper over it.

I tend to favour using that epoxy putty compound, sellys kneed-it or minute mend ect they all look like playdough but sets as hard as steel.

Give the area a good clean and roughen up with a file or wire brush and just mould it around the leaking area, much easier than soldering and its never let me down

Hey, Mick. I had some repairs done to my radiator, just over a year ago. just recently, more weeping hairline cracks have appeared. I went for a new radiator. Since I see that youre running an intercooler, with turbo boost mod, IMHO it would be a good idea to do the same, and prevent a cooked motor.....Good luck....Mick.
