The over flow pipe for the radiator appears to be cracked inside the upper tank, any magic remedied for this. I do have a radiator shop willing to work on it but just wondering if anyone knows of a cure without pulling it apart.
Dennis, Solder flows down hill, so soldering in place is out. There are probably some glues on the market that would work. If it was mine, I would solder it.(after removing it from car)
The break probably happened because the drain pipe was not anchored to the radiator and was able to flop around.
Here's my CHEAP side showing....
I'd see if I could find a piece of rubber tube that has an inside diameter about the same as the outside diameter of the overflow tube. Then, perhaps using a little grease, I'd shove it on there and call it fixed.
If it is leaking on the inside of the top tank, you'll have to remove the back off the tank and repair/replace the overflow pipe.
I had the same problem with my brass radiator....a new copper pipe will fix that problem.
I'm with Henry,
There is no way to get to it without going in from the back of the top tank.
Sleeve like Henry says, or see if you can find the right size heat shrink tube at Radio Shack or Ace for a couple of bucks. Worth a try. The crack may not stop so I'd try sleeving it as deep as possible. For some of this Heat Shrink Tube a regular hair dryer works. Do read the instructions though...some guys think you can use 1/2" heat shrink and cover a 16 ga. wire Doesn't work that way Only shrinks so far.
Is it possible to unsolder the tube at the bottom of the tank and pull it out? Then you just need install a new tube.
What I did on my '24 Touring was pretty easy and works really well.
I just took the radiator off, flipped it upside down, cleaned the area where it goes into the tank, and then gave it a healthy dose of JB-Weld all the way around. I have never had a leak since!
However, make sure you use the original JB-Weld, not the quick setting stuff. The quick setting stuff is only good up to about 200 degrees F, while the regular is good for 550 degrees.
Thanks everyone for your ideas. The tube appears to be cracked between the baffle and the bottom of the tank. I was thinking of maybe trying some gas tank sealer down the tube, let it set up for a little while and then blow air thru the tube to make sure that it isn't plugged. What do you think? Thanks again for burning brain cells on this. Dennis
A third vote for Henry's solution.
My radiator also has a leaking overflow pipe and like Dennis' the leak is INSIDE the top tank so it drains the top tank.
It has been suggested to me to 1. seal off the overflow tube 2. make a new hole in the bottom of the top tank and insert a new tube and solder it in. I just have not gotten to it yet
