Auto Air Conditioner System Repair - 1980 Oldsmobile Cutlass Supreme

****EDIT January 2016*****
For some reason, air conditioning videos bring idiots out of the woodwork. For that reason, all of my household, and automotive A/C videos now require my approval before any comments will be displayed. I am sorry for this, and I know it slows down the discussion. It has become necessary to keep the troll attacks to a minimum. I hope you understand.

In this video, I do a complete flush and re-seal of a 'virgin' R12 air conditioner system. This car was parked 3 years ago and has not been on the road until this week. I show removal of the hoses, tubelines, orifice tube, and dryer. Show flushing of the coils, re-filling the oil and the refrigerant gas.

In this case I use the refrigerant gas HFC-152A. The procedure is the same for R134A.

Note that further system repairs are needed. The system was cold, but the airflow was small. The in-dash vacuum system has a problem and the air is not being directed to the proper areas.

I found some jerry-rigged vacuum hoses and have fixed them.

As you can see on the temperature gauge, the system will make about a 40°F temperature drop (blowing 55°F air on a 95°F day). This is within specification for this car when new. That's a success in my book!

Time will tell how long the charge remains in the system considering the compressor and hoses are possibly 20+ years old.
