AC line patch?

[stantmann]

I put a r12 to r134 converter on my low pressure line and tightened to much. Now I have a leak at the intersection yto the line. Can I use aluminum solder to fix this? Somebody told me to I either have to replace the line (nearly impossible with the 3.4 on the low pressure line) or get it welded. I figured there is another option for this using solder. True? Help anybody?


Thanks,
Dennis

I don't see why soldere would not work using a soldering gun (not iron, it would not get hot enough). Although I have never soldered anything other then electronics (specifically aluminum, which I belive the A/C lines to be) I can not be sure how this would work. Let alone IIRC the adapter for the R12 to R134a fitting has an O ring that needs to be in there to prevent leaks, but then again solder could prevent leaks better then an O ring. If you do try this, use acid core solder (for plumbing, can be had at Wal-Mart, Lowes, Menards, Home Depot) vs rosin core. Rosin core is strictly for electronics, and acid core is for plumbing. Good luck and let me know how this turns out. If it turns up bad, make friends with a TIG weldor (welder being the machine, weldor being the person, lol) and buy him a six pack.

dont forget jb weld. works good on aluminum.

I have a good story. After putting the water pump on last week, I wanted to make sure the seal was dry. I let it sit overnight. I then filled the radiator up and started the car up, it was leaking of course.
I was thinking about it yesterday, and realized that maybe I have a bad water pump, I filled up the radiator/engine again, with the pulley off. Sure enough it was leaking from one of the seep holes. I took a water pump off my spare 3.4 engine (I hate using it for parts), and put it on with the broken bolt, and a standard gasket - Voila! it doesn't leak.

Now we know - You can put a water pump on with a missing bolt and it will not leak. Yes, Yes, Yes!

It dependes on whether it the return line or the outher one.

I don't know much about AC as far as what dose what. I know how to check for leaks and leaksealer will screw up a vampire(AC recycler machine). I do know that one line is high pressior and the outher one isn't (like power steering lines).
so one can be patched an the outher will probaly just blow the patch off.

There is one to find out though.

Aluminum solder will work but I don't think it will be a long term fix as aluminum is not valance material so flux might not bond the aluminum on aluminum like tin/lead sold does for copper or silver/tin does copper water pipes.
