V12 AC Compressor Removal




I'm hoping it can come out the bottom, but I'm guessing it has to come out from the top.
I haven't looked it up on WIS because it probably has the S550 not the S600. They are similar, with the ABC tandem pump sitting on top, but I'm guessing the V12 has far less room.
Any advice welcomed. Regards... Mark
You have to pull the radiator fans and the fan shroud first to get any kind of room. Then you can get to the compressor bolts. It's tight, but it beats dropping the subframe. Expect a lot of skinned knuckles.

That's what I thought. No one mentioned the ABC pump. Does it have to come out? I'm hoping not... Alexie said just the fan and shroud. John said fan and rad. Is it worth taking out the rad, or can you work around it?

Replace A/C compressor, alternator, water pump, serp belt, belt tensioner and idlers.
Consider giving it a fresh radiator at the same time.
I mention this as well.... take a stab at what series of failures I got to deal with inside of six months with my 221 S-65.
The Duo-Pump doesn’t get touched.

I have 77K miles. I'll take a look at everything when I'm in there. I'll have plenty of time to order parts, given the scope of this job, and how long it will take me...
