398 does not have operational AC, although it did before I did the engine swap. The lines were left open and so I know the dryer is f'ed, and I plan on replacing the expansion valve. I'm refilling the system with R12. These are my questions:
Is there a drain plug? I'd like to replace the oil (every 27 years seems appropriate), and I'd prefer to not pull out the compressor if possible.
How hard is the expansion valve to get to? I know you can get to it via the glove box and I've read the FSM... maybe I'm making a bigger deal out of it than it is, but it isn't making sense to me.
Does oil only go in the compressor? I read somewhere that 2/3 goes in the compressor, and 1/3 goes somewhere else, I don't recall. I'm inclined to put it all in the compressor, but just checking.
Thanks!
