Getting close to yanking the engine out of my 91, but I don't know what to do with the A/C compressor. Doesn't seem like I have enough movement in the hoses to just push it off to the side. Last time I did this the A/C didn't work on the car I was working on, so I just unbuckled the hoses and put the compressor on the bench. This one works however and I'd like to not open the system up. Any suggestions?
 
I guess it doesn't matter now. I was pulling the rest of my CAI off to make room for the compressor and one of the lines started hissing. I wasn't even touching it, so I guess that's where my freon leak was at. Once it finishes I guess I'll just unbolt the lines like I did my last car.
 
Dont crack a line if you don't have to. Minute you do, the accumulator will need to be replaced. ANytime the system is opened up, they absorb moisture like a sponge

Isn't that why you have it vacuumed down prior to re-oil and recharge?

Were it me, (once upon a time it was), I'd go ahead and replace the lines with the braided lines from Summit.
 
Yes and no.

The accumulator contains a desiccant which absorbs moisture. Leave the system open long enough and it will soak up a lot of moisture. If you crack a line to change an o-ring and then pull a vacuum immediately, you can prob go without changing it. If you disconnect a line for days and leave it wide open, then you really should change it. Pulling a vacuum for 24-48 hours might save it.

Technically, the accumulator should be changed every 5 years....but who the he'll does that?

Also, a lot of manufacturers void the warranty on replacement compressors unless the accumulator is replaced as well.

Basically...avoid opening the system at all if you can help it. If if you have a leak, keeping it pressurized keeps moisture out, vs letting it stand empty and allowing moisture in.
