I am installing headers on my 95 Z and I decided to remove the AIR system while I'm doing it. Well, in the process of cutting my AIR pipe on the passenger side(up by the header), I slipped up and accidentally cut the AC pipe right next to it. I barely grazed it and it started leaking out air. It eventually ran out and quit reminding me of my mistake. Can I replace just that line? And if so can somebody give me an idea of the easiest way to do it?

 

You can get it at RockAuto.com for $72. Part number 1530481. You might need to disconnect the passenger motor mount bolt and jack up the right side of the motor to get the hose out the bottom. To remove the bolt that holds the entire hose assembly to the back of the compressor (yes, you need to buy the whole hose assembly), you will need some long extensions and you will appraoch it from the rear of the motor along side of the transmission (13mm socket).

It is not difficult but it takes some angling to get the hose out since parts of it are rigid. I did it a couple of months ago when the schrader valve went bad and couldn't get the old one out.

Thanks for the reply. I managed to get the hose assembly off of the back of the compressor and I'm waiting on a new one. I didn't have to take the compressor completely out-just loosen it enough to get it in and out of the way. I did have to unbolt the sway bar and maneuver it around a bit to pull them out the bottom.
What all do I have to get done to the AC system once I get the new lines in? Is it something I can do myself?

 

As long as you did not spill the oil out of the compressor or let metal shavings get inside any of the components from when you cut the line, you need to have the system pumped down (take out all of the air) and then filled with refrigerant. Moisture is the enemy of your AC components so keep everything sealed as best you can until the new line comes in.

Since most people don't have an AC pump and you need a license to buy the gas (I believe), you are probably going to need professional assistance.

Make sure you leave the pressure sensor connector off (located on the line near the right shock tower) until you have the system evacuated and filled otherwise damage to the compressor could result. This will prevent the AC system from coming on.

 

You can rent a vacuum pump from any autoparts store and perform the refill yourself. But, you do need a manifold to keep the vacuum pulled on your system or as soon as you pull the pump off, the ac system will fill with air. I did a little research online and found this www.redhillsupply.com/ho-to-vacuum-ac.htm. You can buy R-134a from walmart for about $5 a can.

 

You should also replace the drier (IIRC) and the o-rings (The new line may come with new o-rings just be sure to lubricate the o-rings with the proper oil before installation). You really should flush the whole system and refill with oil as well though.

 

FYI - My line came with the O-rings and the oil is a mineral based oil intended for AC use.

 

Theres a specific weight for gm systems, can't remember it off the top of my head but don't believe the autozone people theyl'l try sell you whatever they find first.

 

I think you are talking about the oil inside the compressor. I meant the oil for lubing the O-rings and seals. Are they the same thing?

 

I typically use the same thing.

 

The A/C dyer.... I am assuming is the silver can correct? Also how does one pull vaccum on the A/C system at home with the rent-a-manifold set? Thanks!

I used the wrong name, its the orifice tube filter apparently http://id-usa.com/images/ac/Photo_D_tn.JPG . The small plastic mesh screen that should be replaced.
