AC line damaged...

My AC line next to the air intake was rubbing up against the intake hose clamp and caused a leak in the line (H). Is this something that can be easily fixed with some type of sleeve? Or does it require replacing the entire line?

You can try patching it, I would have it evacuated than cut area out and reconnect using a coupler with compression fittings. After repair have it evacuated and leak checked before recharging.

from the mechanics I've contacted, they all suggest replacing the line. No one suggested patching or retro-fitting with a coupler. Estimate is about $500 to fix.

HotRodG35, can I simply use a copper coupling with compression fittings and o-rings from Home Depot? or are there specific types to use? I suppose I can go this route first to see if it works before replacing the entire line.

Thanks for any help you can provide.

I wish I thought of that when I had the issue. I was lucky, I found the AC line on craigslist for only 10$ bucks!!! Installed it myself too lol.

You can use a brass coupler with compression fittings which does not require o rings. This is a common method of repairing Residential/Commercial AC lines with minor damage. This method will work if done correctly. Your AC line pressure should not exceed 55#, the brass coupler is more than capable of handling the pressure. Factory AC line has enough length to allow small amount of removal.

You got lucky finding that deal on a AC line. Ultimately its more work but your keeping the OEM integrity, good job on the DIY installation.

Had the same issue and tried to use a compression fitting but then just went ahead and bought a used line for $30 and fitted it on. I'm driving cool now.

jwrape, that's basically the same location where mine is damaged. I can get a new line for about $50 shipped, which isn't a problem. Where'd you get yours from?

How difficult was it to get the line out? Did you evacuate the system first?

Thx!

anyone have any ideas how to take off the hi pressure line attached to the firewall area? I don't have the Inifiniti tool, but got one of the Lisle ac disconnect tools that slip over the line and supposedly helps unclick the line, but I couldn't remove it. Should it just pop off with ease? Am I supposed to pull on the disconnect tool and the line at the same time? Looked like it was going to be easy fix, but now it's going to take more time...

hmm im not positive about what your talking about...maybe take a pic...is it a plug? most of the plugs or hoses in our engine bay are easy to take off...the plugs have a little clip on the bottem you push in and wiggle it free and hoses have a metal ring [forgot the name] that you losen with a flat head and then use a little muscle and pull it free...worst case senario is you break a broken part a bit more...you can always call your local dealership for advice they wont charge for for that...

it is the AC high pressure line plug that plugs into the firewall line. The little white ring that clips into the plus is missing a "clip" and it won't push in to disengage the line.

On another note, is there any chance of damage to my AC condenser or compressor or the system, if I don't get this fixed right away? As soon as I found out about the leak, I have not turned on the AC and will not until it's fixed. Should it be OK?

Ended up having to buy the Nissan/Infiniti AC line disconnect tools to finally pop off the line, as I could not find this at my local parts store. Paid $17 for the 2 tools to disconnect the hi and low pressure AC lines. Used them and they easily popped off. Now to get the new line in there, vacuum, and refill...
