Motor Drop - Leaving A/C and Hyd. Pump in Car
So lots of great tutorials out there that have been incredibly helpful as I work through my engine drop.
One area not clearly addressed is how to go about leaving in the A/C and Hydraulic Pump (for steering and clutch assist).
Hopefully with some help from you guys to get me through this, I'll come back and make a more cohesive guide for this part.
I'm really close to pulling it out. Just a few more details.
QUESTION: How do I go about getting the A/C out? The A/C clutch has a wire that goes behind the hydraulic pump, and then out of sight near the injectors.
I've already:
1) Removed fuel lines to the fuel cooler
2) Removed 3x bolts securing the A/C compressor
3) Removed the accessory belt and hyd pump pulley
4) Removed 2x 13mm bolts holding down the reservoir to pump
5) Removed 3x 13mm bolts, and 2x 10mm bolts behind the hyd pump pulley
6) Removed the quick hyd disconnect
Am I missing anything before the hold contraption lifts off the motor?

sometimes the wire to the a/c compressor is routed BETWEEN the p/s pump and reservoir. if it is give it a light tug. it has a clip on the end. or remove the power steering as a complete assy. with the reservoir. if you separete them petosin will go everywhere.
if you have stock slave the lines on the p/s reservoir will have to be disconnected and capped. the main lines can stay on. remove the pulley first. theres bolts behind it that mount the pump.once its free lay it over the back of the car. (bumper removed, i lay a thick towel down).
then the ac compressor can be removed . remember the wire! i then use a bungee strap to secure them so they arent pulling on the hoses.

leave PS pump on engine, remove top return hose and spin the pulley by hand, pump out most of all Pentosin in system...nice and clean pressure hose removal and gives you a system flush upon reinstall

That same connector had me stuck for a couple of hours too.
I suspected that previous owner had done something with the wiring, but it turned out that this is the way porsche did it.
Before doing anything with the PS, pump out all the pentosin you can.
If you spill you have to pour alot of water on the waterpipe and whatever rubber it comes by, and that usually is messy especially in a regular garage without any drainage.

Yes, pentosin is a nasty thing for rubber. I've got rubber plugs in all the pentosin lines I've pulled that go to the chassis: upper quick release, and lower feed to the pump via copper coupling.
