I got a radiator from a wrecked EVO 8. It has a small 1/8" hole in one of the colling fines. My grand plan was to take some aluminum welding rods and a propane torch and 'weld' a seal over the hole.

Should it be that simple or am I just going to make a mess?

 

once a friend had a pinhole and wa leaking fluid, so i sandwiched a lot of rtv sealant in between 2 small square pieces of thin aluminum sheet. then used a ziptie to go through the fins on each side of the squares, and ziptied it tight. still works fine. no problems

 

I soldered up a radiator once, it held up until I sold the car (3years+)

 

it will work!

I have a similar story. I had an aftermarket 2 row radiator for a CRX and the radiator fan was bent and owned half of the radiator with nice giant holes. So I cut it in half and soldered some metal on the endtanks. Turned out to be a nice halfsized radiator for a CRX.

 

Let the painter do the painting
and let the plumber do the plumbing Get it?

no way man .. that will not work .. u wont even get the metal hot enough to weld .or solder ..

use some two part epoxy .. that stuff that comes in a tube and looks like gum .. i used it to patch a 1/2 hole in my rad .. worked till i sold it .. **** works .. the the one that is solvant safe and adhears to metal .. DO NOT use the **** u put threw the coolant system to patch holes ..

 

either have it tig welded or use por 15 epoxy putty. here's the specs and link for it.
