560SL - AC Compressor Install - Oil Balancing, R12 to R134a

UPDATE!!! Total PAG 46 oil capacity for vehicles with Nippondenso A/C compressor is only 220ml instead of 300ml you see in the manual.

In this video for I stated that the manual was for a Delco/Fridgidare A/C compressors and not for the Nippondeso.  This bothered me as you know. The Delco/Fridgidare compressors oil capacity is 200ml. For the Nippondenso it is 120ml which is 80ml less!

PAG 46 Oil For Nippondenso Compressor: 120ml
PAG 46 Oil For All Other Components: 100ml
PAG 46 Oil System Total: 220ml

I have already added 200ml of PAG 46 to the compressor. So I will add 20ml of PAG 46 to the evaporator when I install the Expansion Valve. I want to thank Tom (   / @coldfinger459sub0  ) for pushing me to further investigate this issue.

In this video, I balance the perfect amount of PAG oil for optimal performance and compatibility with R134a refrigerant. Additionally, I also install a new AC hose to compressor, complete with compatible O-rings suitable for R134a. Learn the ideal quantity of PAG oil and R134a refrigerant that Mercedes recommends for your older Benz.

I am documenting every part of the 560SL restoration build . The idea is to end up with the best documented 560SL rebuilds on the Internet.

I want everyone who visits my channel to know about a friend of mine named Tasos. His videos inspire me to be more like him. He is so much better than I am. You can find his YouTube channel at:
