Need new radiator for 55 2nd series - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Started truck today after a long time off. Timing still needs some work, but discovered a huge hole in the (brand new) radiator that I must have put there myself sometime in the last year of fabrication.

Where would be a good place to get a replacement radiator that would mount in original place? not original engine, now running an Olds 455 (until I find a SB chevy to put in)

I got one for my 59 out of a 57 big truck (6400??). It has the same mounting pattern to the radiator support but is 1" thicker and about 3" taller. I never had any problems with the old 6 cylinder one I had in there but figured since I was upgrading may as well get some more cooling for the a/c.

When I needed a radiator for my 52 last summer I talked to a radiator shop. His advice was to go to ebay motors and search. I paid about $250 shipped for one that dropped right in and works great. The vendor I used is currently out of ones for the 55, but there are others. Get the 3 row core, it should keep that 455 cool.

Thanks for the info. Found a couple on Ebay I will look at.

How hard is it to fix these radiators?

I have the old one that came out of the truck that may be a quick fix until I can afford a brand new on. I am very handy at brazing and welding, and it seems the leaks are only where to top and bottoms join the rest of the piece.

The area has to be clean inside and out to solder. Then submerge the radiator until the seam is above the water. It's been years since I soldered one usually had a shop do it, they can do it a lot better. I also learned that shops are hard to find. They were forced to close when the price of copper skyrocketed. These aluminum radiators have dealt the shops another blow.

If the hole didn't take out a lot of tubes I'd pack the "new one with the hole" down to a radiator shop and see if they can repair it. If the rest of the radiator is in good shape they should be able to solder it and send you on your way.
