Yes ,that is a good catch

I am replacing the dryer

The hoses were just in my garage so I believe I will be ok

Thanks everyone

I have a 70 chevelle that had a working,although poorly,ac system

I have replaced everything and had the POA valve restored
New evaporator,compressor and parallel condensor

Going back with r12

The hoses look to be in like new condition

They have a been disconnected and we're open on the ends ...

Outside of the basics like a little lubricant on the fitting threads, cleanliness etc, most of it is basic mechanical work.

You have chosen R12 as a refrigerant, so there is no need to recalibrate the POA valve. Use mineral oil, check the oil in the compressor sump.

I would drain the compressor ...

Thanks for the link
Very good read

I would love to have the shop do the whole thing and may do that

1 thing I would like to do while the engine is out is the evaporator

Can anyone offer any advice on doing that,also mating the expansion valve to the evaporator

Thanks
