Replacing a radiator overflow hose

Dave H (MI) · Dec 31, 2010

Got my rad back from the shop. Had a pretty major leak near where the tree hit the hood. The overflow hose is gone. Rad shop was going to put on copper but it was pretty pricey. I have some copper tubing around and pretty handy at soldering. Was going to give it a try but thought I would ask if anyone had a good solution before I forged ahead. Anybody with an easy fix to a missing rad overflow tube?

I just used rubber gas line tubing of the right size and length desired, worked great for me and no soldering needed.

first of all what is this on? tactor? truck? dont see any problem with soldering in a piece of tube. have heard to put zinc slivers in muratic acid and let them dissolve and then this is your cleaning mixture before soldering. should be able to use a short piece of tube then connect with rubber hose but dont know your application.

He's got a Cub radiator that he was trying to get tested a few days ago.

The copper or any kind of tubing would work even the rubber hose only need it ir the rad is over filled.

I replaced the one on my 300. Just soldered it to the neck and bent it around the radiator where the old had been. Fairly easy.

Sounds like I am on the right track. Dug out some copper tubing I had from an old humidifier. Heading out to give her a try.

For what it's worth, when I recored my F-20, I used 5/6" copper heavy wall tubing and soldered it in. You have to clean the the line and tank REALLY well before you start.
works fine, and doesn't leak.

I did have to use the acetylene welding tip to get enough heat though. you need to be real careful, and heat the tubing......too much concentrated heat is no good for the cast. I tinned it before I put it in, then heated the brake like, and pulled the solder in. I did the tank side first, then turned it over and did the rad side last, to let the solder work down and around.

It would be interesting to use JB Weld for this job. I have had excellent success with JB weld for repairing the oil cups on the air cleaner and similar sheet steel parts.
