It's very possible! 'If' it's not a case of rot.
If I was going to rip off my dash to pull out the heater core, I would
replace it rather than fix it.
I literally broke my rad in half twice and have soldered up many of it's
cores with some cut off and blocked even because they were just too
stretched to fix. I also welded two 1"x1/8" metal bars up the sides to
reinforce the snapped in half side straps. (my lower tank was just
hanging on the cores..)
I first broke it about 4 years ago and have nursed it along until a
couple weeks back when I took it in for a re-core rather than solder up
3 more leaks for another bush camping run. They even left my heavy duty
side strap braces on when they did the re-core, laughing about it never
breaking again. LOL!
First time in 'years' I haven't had to do a rad fix on a run...
