Solray Radiator Disassembly

Looks to me as though it might be push nipples? In which case... undo the tension rods and you'll need four spreaders (like ball joint spreaders or something of the sort) and very carefully and evenly start spreading all four joints. But... that's a guess.

What you need is a hydraulic spreader. If you know any body men, they might be able to help you out. Otherwise you can get small, portable ones for about $100. Ask your friend to do you a favor and buy you one.

Otherwise, try punding a wooden wedge in between the sections. I wouldn't go at it with a chisel if I were you. Especially not an air chisel.

That might work -- a few taps at a time on each of the four points... once you get it to move at all it will just come right apart (yeah, right...)

I never spread that type of radiator but for the regulator column rads I always used wooden wedges that I cut myself.

Nice work! See -- it wasn't that hard.

You could also use redi-rod with nuts and fender washers. Whatever you do, make they go in straight.

Gorgeous 😍.
