DIY: A/C compressor removal and installation
Well, I could have paid someone to do this for me, but I figured I'd better DIY so I could share pics and info for anyone wanting to do this. (the things I do for you)
So here's a short writeup with pics.
1- remove the battery and tray
2- remove the main belt from the engine by loosening the tensioner.
3- disconnect the main A/C electrical harness and 2 coolant lines
4- go under the car and remove the ground wire bolt and harness
5- (optional) remove the oil filter (you'll thank me later when you go to remove the lower bolt)
6- remove the 3 bolts that hold the compressor in. I prefer to do it from the top front, then top back, then bottom.
7- slide the A/C compressor forward and rotate it for best maneuverability while pulling it out the top of the engine bay.
*Note- there is a small "z" bracket on the ground cable bolt that connects it to the compressor. Make sure you re-install it.
Reverse the directions for re-installation.

I did this on my hooptie. It's just used for testing nowadays. It logged 45 miles in the last 5 months I drive my sandstone one as a daily.

So you just charged it up with some r134a and it's been good as new since?
On my SC3 I can't pressurize the a/c system as much as it should be since by doing that the a/c compressor just engages and then disengages every 10-20sec.
The other thing I've noticed is after a drive at a high rpm for 1-2 min (5000+) or a drive at 85 for awhile I'll smell a burning inside my engine, already replaced the waterpump so I think the compressor clutch/compressor itself has to do with that. What caused you to replace yours, just loss of r134a?

Whats the seceret to getting to the rear upper bolt? My cars been apart for ever because I can't get the AC compressor off to change the water pump.
I boght a 14mm (built-in) universal socket, but have not had time to use it. I can't seem to get a socket up there. Are you accessing from the top or bottom?
