Soldering the overflow tube

[ShawnAgne]

Ok I resoldered the overflow tube and needed a 3rd arm. Just wondering how you guys do it so that way in the future I know, plus I need to resolder the one on the 300 here too.

make sure the tube is clear, I found many are plugged up and nothing will flow through them

[ShawnAgne]

Oh its clear..........

I know what you mean about a third hand.

Just thinking out loud: could you use a wood dowell thru the filler neck into the tube opening to hold it in place while soldering? Then remove the dowell when done.

I have used a tapered drill bit and flaired the tip of the piece on the radiator. If you are careful you can get tip so the tube slips inside enough.

I then use a two-part epoxy instead of solder mostly because of my several failed attempts to solder it correctly.

[ShawnAgne]

Epoxy is a good idea, be easier to use and be stronger. That is what I'll use on the 300, thanks.

i layed my radiator flat, put the overflow tube bracket down below, and used various flat washers and masking tape to hold the pipe away from where i was soldering. acetylene torch with a flame so weak that it curls up at the end, i've watched a few old timers repair radiator tanks and it looks like they solder with a candle flame - enough heat really close for solder to melt, but not so much that it travels far to melt solder further away. very clean, good flux, and it sucks right in.

In the how to section someone posted a how to without soldering, all I remember is a screw with hole drilled through it.
