I 'm not a car expert and would appreciate any expertise I can get on this subject.
I have a 2000 Nissan Frontier and one of my AC lines has a hole in it. I believe it’s the high pressure line, but I'm not familiar with the terminology. In any case, it seems to be made from aluminum. I was about to just go to the Nissan dealership and buy a new part, but I was wondering if I could patch it with JB Weld or some other compound. Its my understanding that welding aluminum is not advised. Expert advice would be welcome.
Thanks.

Man, JB cant hold all the pressure that A/C system packs....you are SOL, those thin lines cant be welded either due to oily film on the inside....get a used/new line

Try the Jb weld... what would you be out except for 134a??

If it doesn't hold you've got your answer. Then get a new line.

JB weld wont do the job, BUT there's a putty that is made with 80% aluminum powder and 20% epoxy. This stuff is soo hard and bonds so well you can drill and tap into it. I have used it many times including sealing a huge hole in my dirt bikes engine case. I sealed it with some of this putty and a peice of stainless steel screen as the matrix. It lasted another 10 years of hard riding. It's called Devon F and you can buy it from McMatser-Carr.

I just fixed a kinked line by getting it cut and then brazed back together by a local hose specialist. Stuart Hose is the place, don't know if they have them where you live. Works great.

I had an aluminum ac line welded before, it had the same pin hole leak problem you do.

I beleive he is working on aluminum. Brazing uses brass and is used on steel lines.

My cheap ass brother in-law used JB weld on his 01 accord A/C condenser, as of now it's going on a week and still holding. So you if you wanna be a cheap ass then use JB weld, but if you wanna do it right, change the A/C line.

Brazing works on aluminum just fine.

you can get the line repaired or buy a new one...I wouldn't advise stick on fixes like JB for your AC system...If a piece of it gets into your system, you could be buying a compressor, which would be far more than getting a line fixed or replaced.....

I will be purchasing a new line as soon as i receive paypal donations from all those who called me a cheap ass, hehe :bigthumb:.
I agree. A new hose is the way to go. I just have to wait for my bank account to catch up.
Thanks for all the input, everyone!
