Braze a plastic tank?

Just replace it.....

 

Yeah he's proly old school like me, from way back in the 1900's, when radiator tanks were metal...

I did consider JB-Welding mine, until I read this thread, and it would seem that both tanks are soon doomed once one starts leaking, so...

 

Lol chuckle...I'm old school as well but the OP mentioned that the leak was in a plastic tank and I had to tease.

 

I got my new radiator from Advanced (promo used), but it was a Delphi one that was drop shipped directly from their usa factory. Plastic repair on my cracks lasted for about 6 months. I new it would not last.
