CJ7 - DYI Radiator Repair?

[Roger]

My Radiator is a few years old and I noticed that it's starting to seep a tiny bit in two places along the solder joint where the upper section is connected to the core section. It only leaks a tiny bit after the engine is warm and the cooling system is under presure.

The solder looks like regular 50/50 solder. Has anyone ever tried to re-solder a radiator themselves? I have a map gas tourch and some 50/50 solder. It seems that if I lowered the coolent level below the leak and cleaned the area really well, and re-soldered the areas in question it should work.

Is this something that should be done by a radiator shop?

Is there anything I'm missing?

The solder is 60/40. The area must be clean and the flux is very important.

It sounds like you have a tube to header leak just below the top tank. The radiator will need to come out since getting solder to flow uphill is usually a problem.

If you don't have any luck yourself keep me in mind

Okay, I looked up my radiator purchase and I saw that it came with a limited lifetime warranty - I forgot. So I called the company and they are sending me a new one and will credit my acount when I send the old one back. I'm pretty happy about that!

Good job!

FYI,
I forget which ".com" bought up all the other radiator .com's out there. But, I think 99% of them are owned by one company now. This happen 10yrs ago? Radiator places are usually good about returns.

As long as you have a copper and brass radiator, and you clean it good rosin core solder works well, for cracks in the tanks you use brazing rods that they use in refrigeration. regular solder does not work very well for cracked radiator tanks
