Hi Vette Experts
I am working on my 08 coupe base AC compressor replacement, shop already evacuated the AC system, after I remove nowgot suck with removing the AC line connector that connect with the compressor, I noticed there is a bolt that holds the AC line connector but since its so close to the frame there is pretty much no room for a socket and wrench to go in there. Then I tried to loose all four bolts of the AC compressor, but one of the AC line is against the top bolt when taking it out. Please let me know If anyone knows what should I do or what tools can I use to take out the AC line connector.
Thank you so much.

 

See if any of this helps..............

For when I do mine some time, I bookmarked a thread HERE that one member did.

And wrote this in my service log from another:
Car on ramps and remove passenger tire. Remove 2 lower compressor bolts. Remove 2 upper bolts. Slide compressor forward and rotate to remove lines. Loosen motor mount bolt and jack up engine about 1 inch. Compressor comes out very easy. Make sure you replace mounting stud before you reinstall compressor. I'm 72 and took anout 3 hours to remove and replace. (7mm to remove stud on compressor)

 

Thank you C6ToGo for sharing the experience. I ended up figuring it out on my own because I didn't want to risk jacking up the engine. Here is what I did:

I removed the two bottom bolts holding the compressor and completely loosened the stud that secures the rear top of the compressor. Then, I loosened the top right bolt about 85% (without taking it out, using it as a pivot point). This allowed me to wiggle the compressor slightly, so I could lower the rear side by about two inches. That gave me access to the bolt holding the AC line connector. Once I disconnected the AC line connector and moved it out of the way, I had enough room to remove the top right bolt holding the compressor. Please see my attached pictures. I think this is the trickiest part of the entire job.

Oh, also: GM no longer makes the original OE AC compressor, so aftermarket is the only option. All aftermarket compressors come with a cap that covers the low and high side, with a stud in the middle. Due to the tight space when installing the new compressor, you MUST remove that stud using the two-bolt technique (tighten two bolts onto the stud, then remove it).

Be careful to prevent debris from falling into the compressor. I used plastic food service film to cover the low and high sides so no debris would get in while removing the stud. Hope this will help.
