This car (Carmen) had a dormant R12 system in place.
I had a donor car that had been converted to 134A. This donor was working fine with a new compressor when I purchased it.
I removed the new compressor (Tama) from the donor car and put it and the 134A high pressure port in place on Carmen several years ago. I did not pursue charging it at that time.
I am preparing Carmen for sale and want to see about charging the AC system. I expected to find a low pressure port on the back of the compressor, but as you can see from the photo there isn't one there.
How would the system have been charged without a low pressure port? How would I go about installing a low pressure port on this system.
Thanks for any help,
Randy
