So.. minimal force it snapped right off. Uh.. short of replacing radiator do I have options?
Solder it back on. If you can’t, JB weld it. I’ve done both with good results. There is never pressure in that tube so it’s not that hard to re attach.
A certain kind of jb weld? Coolant resistant? I found a metal valve stem that I'm this close to hacking off but that would be better.
I was thinking a threaded barbed fitting for a totally external fix. Or, a tube of the right size JB'd in.
Either way, jury rigging for the win !
Do you think tap it to the nearest barb and install, then put a nut on the back of it? PTFE of course? Or JB weld the barb?
Hang in with me here... just think about it... threaded rivet insert??????? Lmao
Anything that is not flush with the inside, may effect how the pressure cap operates. Solder back in is the best fix. If you just leave it out the radiator will overflow a little then seek a level and stop leaking.
Get it fixed when you can later.
So, perhaps, solder the broken piece is the best answer followed by the tapped idea but flush as per @Turbo4whl.
Which is easier for you?
I'd wire brush the neck area and the nipple and solder them back together. Find a plumber. If you prep it they may solder it for a 6-pack.
I have family that know how to solder pipes, id imagine the concept is the same just applying on a small area?I could try it myself, too, i have about 30 pounds of solder around my house thats all ancient(probably the good stuff, too) and torches
Watch a couple of videos on brazing and go for it. A Sil-fos variant would likely be the way to go. Put a silver dollar or something to prevent stuff from falling into the radiator, the use a vacuum to retrieve it from the neck.
Couple things about soldering, don't need a big torch, a small Bernz-O-Matic will work fine. Both pieces need to be cleaned well. If you use something like JB weld and it fails, you will have a tough time later trying to solder. Need to coat both clean pieces with flux.
Most important, the solder will flow to the heat. So heat one side. Apply the solder to the opposite side. When the metal is hot enough, the solder will flow in. Remove the heat and add just a little more solder, then stop.
Watch some videos like @Frankenchevy stated. Practice on something else first. You can do it.
Shitcan it and do an LS Swap. Then a new radiator with be an ancillary purchase anyway.
Wow, rough. Are you buying? I'll take one too.
I’m surprised at the number of tapping / screw in fitting suggestions, y’all need to pay attention to the material thickness. That neck would never successfully tap even if you could find a flush fitting.
