R12 Refrigerant

[angusbn]

How much R12 refrigerant can be installed in a AC cooling system - I suspect it's bone dry now.

[Bob in San Jose]

According to the Bentley manual it takes 4.24 pounds.

Don't forget to vacuum and add oil while you're at it. Don't want to burn up the compressor if everything has leaked out.

If it leaked, I would do a pressure test and replace leaking seals before adding new R12, otherwise waste of money and time.
