Went to my friend, Al's shop to add some R12 to the a/c system today. The system was a little low. According to Rick, the original owner, the car has never had its a/c serviced, so after 41 years it still had 75% of its original R12 fill.
I had a couple extra cans in the garage and my buddy Al is an expert at reading a sight glass in these old systems. It was 85 degrees today and now while driving, the test thermometer in the center outlet read 40 degrees on max a/c. Nice!
