Default Leaking Upper Radiator Inlet

Question on radiator leak/issue on my '80 L48.

Radiator: Modine replacement radiator purchased new around 1998-1999 from Western Auto (no Advance Auto).

My upper radiator hose inlet appears to be leaking around the seam where the inlet is attached to the radiator. Upper radiator hose does not appear to be the culprit but as it is nearly 5-6 years old, I am going to replace it as a first step.

My question: If the inlet is leaking, given the radiator is likely brass, can this be resolved with braizing/solder?

Who sells a good (GoodYear?) replacement upper radiator hose for the '80 L48 that doesn't cost an arm and leg (ie. no 200% markup on price)?

Purchased an upper rad hose for $15 at my local NAPA...

WALKED to the store (4 small-town blocks away). Funny, with the increase in price of gas, I stand a good chance to finally lose those extra pounds by shopping locally instead of driving to the nearest 'big town' or ordering/shipping to my door...

yes the rad can be soldered, usually with no problem. Any competent rad shop can do it. Soldering takes some education and some talent, but you can learn it yourself. My recomend would be take the rad out and take it to get done and pressure tested.

I had a leak where you described on my '71 aluminum radiator. I took it in, had it soldered and it still worked fine 8 years later, when I took it out in favor of a Dewitt's radiator.

If it is a small leak and you don't want to remove the rad, you can use marine epoxy to plug it. Lasted several years on a friend's car (until he sold).

Is that the same as 'Marine Tex'? I remember buying it in a small jar. Was white in color. I used it to seal/repair aluminum motorcycle block back in early 90's.

I'll be removing the radiator and taking to a local repair shop for repair and pressure test.
