York compressor bracket removal: Coolant leaking out??
Hey folks,
I'm in the process of removing the York Compressor from the old 240D. I was just loosening the bolts to make sure everything would come off without issues. When loosening the lower 14mm (red arrow in pic) bolt on the front (beside the water pump), some water started leaking out. Does this actually lead into the pump housing and will I loose a great deal of water by removing the bolt? If this is the case, then I will drain the radiator and conserve as much coolant as possible.

On my 240D, that bottom bolt actually also holds the water pump housing to the block. I found this out the round-about way, when I was replacing the t-stat housing gasket. I couldn't figure out why coolant was pouring out behind the water pump when I pressure-tested it ... well, I didn't have the bracket back on yet, so the water pump housing was loose.
In my case, when I first removed it, I didn't see any noticeable water leak out ... it was only after I pressurized the system. But my housing was pretty well stuck to the block by its gasket. I don't think coolant is going to pour out when you remove it ... it would likely just dribble out, since there's still a bolt holding the other side of the housing on. I can find a picture of the housing, if that would help. EDIT: Added a picture. The bolt in question goes through the hole circled in red. That might help add perspective. EDIT II: Actually added the picture this time.

Thanks Bodhi,
Water is actually dribbling out in a pretty constant stream. That would tell me that the other bolt isn't completely holding it on that well. I think that I will drain the radiator and maybe the block just to be safe. I can always refill the system later, but I don't want a major mess on the garage floor. I might replace the gasket while I'm in there. I'm sure that it's not all that new and the movement while removing the York bracket will do nothing positive for it's condition.

That's what I ended up doing ... even though mine wasn't a stream, once I realized water was leaking past the gasket, I figured the odds of it sealing tight again were not good. I figured after 366k miles it was probably due for a new one. Once the coolant was drained, it was pretty easy to take the housing on and off. Plus the gasket is relatively cheap. You may want to replace the little bypass hose under the t-stat housing while you're at it, if it looks old.
I think the worst part of the job was getting that A/C bracket back on. Hopefully yours won't be such a pain, but mine would an absolute bear to get the holes lined up again. I ended up spraining my neck in the battle. Good luck!
