99 U 270 radiator repair

A few years back I pulled the genset and had the radiator cleaned and checked.  I now have a leak at the lower neck and would prefer not to pull the Genet again.
My question is, has anyone repaired a leak at the neck with epoxy or some other product with success?
Thanks Jerry

Coolant leaves an oily residue and you would probably spend as much time draining, flushing and cleaning the area up just to have a bubble gum repair that will return sooner or later as it would to remove it and have it hot tanked and soldered right.

I've used JB weld after brushing off all of the paint down to bare metal and cleaning with acetone or something else.  Lasted many years.  But having it brazed is the best solution.

At this age, I would be worried about the next leak or crack.  It is your choice, but I would recommend  taking it off and having a qualified shop repair it or even just replace with a new one. Everyone has different drivers and limitations and only you know them.

I remember chasing an easy fix on a radiator on an old 1974 Jeep CJ5 I had in college. That damn thing drove me mad and never failed at my house. It would always wait until I was out on a trail hundreds of miles from home. I finally bit the bullet and replaced it after spending way too much time and energy. Man was I happy after that. I never had a cooling issue again.

If I have learned anything with these coaches, it is fix it right now while you have all the control or pay much more later in time and money.

It is always easier and cheaper to fix at home even if someone else does the work you are still in control--not so much when on the road or down on the side of the road.  Granted with a gen set you would not be down on road but would still cost more to get fixed
in most places.  I have decided that when repair shop sees motorhome they start hitting the cash register buttons
as in chi-ching multiple times.

Radiator is in the shop.  Will have to be recorded.
As stated better at home than on the road.
Thanks to all.
