Ive got a small leak in my radiator and this guy at work told me about these small beads that you can pour into your radiator and they goto the leak and melt, covering the hole and fixing the leak. He said that autozone sells it. Have yall heard of this stuff and does it work? Thanks.

 

Get a new radiator.

 

 

of fix the leak, like by using solder and doing it the right way

 

If the radiator core is aluminum, solder won't work.

 

sure it will you just need the right solder and equipment, or you could even weld it, lot of people are welding aluminum now days

 

To weld aluminum you need a TIG welder to do it right. How many home wrenches have a TIG welder?

Tin/lead solder will not stick to aluminum.

 

i have a GTAW welder, which is what people that don't know any better call TIG, and i'd fall in to the home wrench group. you know there are even some forward thinking people welding aluminum with GMAW process and a few people stuck in the dark ages using SMAW and still a few others using a torch.
you're right you can't use tin lead solder to solder aluminum, but that doesn't change the fact that with the correct solder and equipment it can be soldered

 

Or for those of us who use them everyday,the heli arc.

 

These radiators are a dime a dozen. If you're really worried and too cheap to get a good welder to do it or to replace the radiator, then JB weld it.

 

Thanks guys. I had heard about the stuff and didnt know how well it worked so i figured id ask. I just picked up a new radiator today so it will be goin in this weekend.

 

OK, so what solder does work on aluminum? Enlighten us please with some details.

 

solder aluminum - Google Search

seems he isn't the only one who seems to have that idea
