Should I take a stab at fixing this leak, or just go get a new radiator? It might work to weld, but I'm thinking of slapping a heat resistant epoxy on it.



It loses just a bit fluid, which collects along the top seam of the radiator and occasionally smokes a bit. I refill the reservoir about once a week.

 

I'd braze or solder it. Should be easy peasy. As small as it is.
