Radiator swap?
Has anyone on here ran any other kind of radiator besides stock/replacement? I'm talking about rads from other cars. I'm in a money bind right now, and I'm looking into something that will just get me by until I'm out of my situation. Theres a crack all along the top of the rad, and it won't pressurize, and just spews antifreeze.

Same here. I managed to get a free used aftermarket one.
However, I made the mistake of not checking that the aftermarket had all the plugs (was missing the drain plug). Spent hours hopping from store to store trying to find something that would fit (realized the plug was missing after I had removed my stock one).

If you look through the classified and/or post a WTB ad then you may find one close by, or they could always ship one to you if it's not close. There's bound to be at least one decent used S4 rad out there. It'll be a lot easier than adapting something else.

Fixing a cracked radiator is easy. You will need 3 things:
1.) propane torch
2.) plumbing solder (any hardware store like loews or home depot will carry this)
3.) solder paste (aka flux)
If the crack is easily accessible then you can leave the radiator in place. If the crack will be easier to work on with the radiator removed then remove the radiator. Drain the radiator. Use a wire brush to clean the metal around the crack. A wire wheel on an electric drill works nicely. Next, apply a tin layer of flux to the crack area. Use the propane tourch and move the flame in a slow circular motion around the crack to start heating the metal. When the flux bubbles and melts away, touch the solder to the crack. If the metal is hot enough the solder will melt and fill the crack. Do this to the entire crack. Make sure the solder fills the crack evenly. Let everything cool down then refill the coolant system and when you have everything back together start the car. Let it warm up while you watch for leaks. If it leaks you didn't fill the crack completely. If the repair is good, cover the repair with some matching spray paint. And you're done!
FYI radiators are held together with lead solder. If you make a good repair following the steps mentioned above, your repair will be as good as stock if not better. JB weld has its uses but the radiator is not one of them. Do it right the first time.

S4's have plastic top and bottom tanks which do crack and leak sometimes so this is irrelevant for his situation I believe
and the s5 is all copper so it wont crack like the plastic s4
