Let me preface this with:
I went a entire summer (2015) toughing it out with AC.. so without much alternative other than another hot summer... I decided to try a shortcut..

Warning:
Those with weak stomachs or those who can not even think of doing something half-way.. stop reading...

Okay you have been warned..


Last year I was told I have a leak in the rear ac lines and given few options:
1. Plug up rear ac lines but have front ac still work. Rear heat not affected
Cost would be close to $200.

2. Try to repair - possibly weld aluminum lines. Cost if repair works $300 if not work then complete replacement maybe around $1000.

I asked mechanic about ac sealers and they advised against it.

I did some research and found this product named red angel repair. Cost me around $27.99 shipped.

http://www.ebay.com/itm/RED-ANGEL-A-C-Stop-Leak-Sealant-With-UV-Dye-R134a-4-5-oz-/201629974268?hash=item2ef2153efc:g:NpsAAOSwqfNXk3E9&vxp=mtr


Previously my ac would last about 24 to 48 hours before the Freon would leak out.

I put this red angel plus some 3 cans of Freon from Walmart (pure Freon no oils/additives)
Results:
AC run nice and cold for about 2 and half weeks. At that point AC seemed to be not as cold.

So I wanted to try one more thing. I got a bottle of AC Pro Synthetic (has some basic sealing qualities) cost me around $35 shipped.

http://www.ebay.com/itm/NEW-A-C-Pro-Professional-Formula-Refrigerant-ACP-100-Leak-Sealer-20oz-/251480156354?hash=item3a8d62a8c2:g:MzAAAMXQeKNTKZYQ&vxp=mtr

Result, very cold AC.
Now another 1 month has passed (total of 6 and half weeks) and so far, still very cold AC even during the recent hot and humid days in Michigan.

So in total I have spent around $75, but I may have fixed my AC.

Not sure I will check and try to remember to update this post next summer.

I know some people will say that repairing the AC is the right way and I would agree but for me, I could not afford it right now.

*Also not Red Angel claims that it does not gum up AC systems like other sealers.

So far I am very happy. * but please use at your own risk *

Sections of the A/C line can be replace where needed if you have or can find a shop that has A/C line repair kit as such:

Dorman also has a repair kit known as "line splice" which can fix leaks using a crimp union:

So far still cold. I was really skeptical at first but have to say I am impressed.

Lets see if this will last till next summer.

Okay. Leaking now. Pretty bad. I put some freon in and could hear it hissing out underneath the 2nd row passengers seat - under the heat shield. My mechanic suggested blocking the rear lines off since he said any repairs will only be temporary- as other leaks will occur through out the full length.

Any one blocked off the read AC lines? If so, what part or what size?
I found many block off kits for American SUV but none for Nissan.
