The O-rings leaking at the back of the compressor seem to be a common issue on Nissan Maximas, too. I replace them with the green O-rings. My suggestion is to put a dye charge in and check with UV light. Pump it down with a vacuum pump. If the clutch is good on the compressor and there is no dye anywhere else, it should be good to go. Refill with the correct amount of 134A. Buy the vacuum pump and decent gauges. Learn how to use them. You will be glad you did. Both can be had for >$100. A small scale for weighing the refrigerant is good to have too.

Keep up the Good Work :)

Most helpful. Fixed AC in my 2000 Xterra. Had the same exact issue. O-ring where it meets the compressor. Cans only though. I first put in a small 10oz can of refrigerant + dye to detect, and jumping the AC relay. Didn't have the yellow glasses, but it was still quite visible mid day and with a black light taped to a stick. Got the o-rings from Harbor Freight, cheap $6. After replacing o-ring, started at zero pressure, lines empty. AC clutch engaged as you stated after a few seconds of filling. I only filled to just within green to be on safe side. I let it sit and monitored the pressure for a few minutes. Leak is gone! Thanks so much.

Hold it Eric, you needed to use a barium grease on the o ring prior to installation. Lube it enough so that you see a shine on the o ring, but not over lube it. It lubricates the o ring and allows it to slide easily in place without tearing it or twisting it. The o ring will stay in service a lot longer and you will look like the King of AC.

Very Good video !! I saw exactly what I wanted to see
Thanks !!!

Good video. The best thing anyone can do is add a small amount of dye to the system and search for the leak using the blue light. Can't imagine how many compressors were replaced needlessly at a high cost when all it needed was to replace O rings or tighten or replace the schrader valves under the high and low side caps. All DIY guys and gals alike should learn this. I am surprised that with your system line open that it actually took in that can of freon, you would normally has to pull a vacuum. Cheers.

I'm actually changing my AC Lines because one has a crack on it. So this helps! Thank You!

[johnathansmith]

Perhaps it would have been wise to remove the OTHER O ring and re[place that one, too, at the same time... Thanks for video.

[nissanheel]

Thanks! My Nissan Murano was leaking at bottom o ring too at compressor line from condenser and found with dye from Walmart. Getting o rings from advanced auto so gonna be a good summer after all as I was dreading no air!

[Whitemike_]

Should always dab then o rings with some mineral oil before installing. Great video

[eroom]

No vacuuming the system down, moisture is a a/c killer

[mohenprosper]

Great video bro. Keep it up.... helped me a lot.

[Stretch-ldyv]

How did you get the air and moisture out of the AC system after you opened it up

[pingpong]

You should attach your vacuum cleaner to ensure the system is dust free and in vacuum before filling... pro tip.

[tanroyhaywood]

There will be moisture still because the correct way is to vacuum the system before adding refrigerant

[JeffMitchell]

Yo I picked up the same o-ring kits two different times No damage to the components but for some reason those o-rings Don't seem to be working every time I pull a vacuum there's a failure what's up with that!

Just so hapened I used dye to find allot of dye on my line. I then thought bad compressor but after thinking about it and looking at the picture I see it coming from this conection. i assumed maybe it was a evaporator from just searching leaks for my car witch causes allot of work to remove the dash and allot more. I then thought it could be the compressor after seeing all the dye and thinking maybe when i installed my alternator I made the tension too tight that maybe ruined the alternator even that may not be possible. Then thinking I might have to change the condesor too. After watching this video after searching about leaks from suction lines to compressor thanks to the dye that was able to pin point it out, I am confident that it a silly o ring. Thanks so much hoping for hope till I wake up to do this. I so didnt think it could be this easy. Afraid to take it anywhere thinking they can say whatever and might try to charge off the bat and me not knowing could think it could be worst case senario from googling ac issues.

Any time you have to crack open the ac system you should replace the accumulator and vacuum down the system so it lasts longer overall

Hello i just watch the video is that ok if i charge the low pressure valve only..im planning to change my o ring on high pressure and low pressure
