JB Weld + Radiator = ???

Yeah, that Barr's Stop Leak is good stuff, it might work for you. I used it in a '79 TA that had a BIG crack in the side of the radiator. Got me by for a couple of years in high school when I didn't have any $$$...

But like one person said it could clog your core etc, but that might not be a big deal if you are going to buy new eventually. I have heard of people putting in the stop leak, then running for a day so that the leak was sealed good, then flushing the radiator to get all of the leftover stop leak out so it doesn't cause problems...

I know thaata this sounds strange but a little bit of black pepper will usually stop a small leak like that just don't over do it.

I think i'd buy some stop leak or something from autozone before i used black pepper lol.

don't get me wrong I did not say that this was the correct way to fix the problem but it will work in a pinch. Pepper does kinda the same thing as stop leak the flakes move twards the leak and stick togeather kinda like a scab.

Well, if its a 94 blazer, thats the exact same radiator as i had in my 95 S-10.

Whatever, you guys dont wanna head my advice, try everything like i did.


You are gonna have to buy a new one.

the plastic tanks on the ends of radiators get old and brittle after a while. even if you fix this leak, you will be getting another shortly.

junk the radiator. get a new aftermarket radiator with metal end tanks. these can be repaired
