Installed new air conditioning compressor in 2002 Pontiac Grand Prix - how much compressor oil do I need to put in?

If you have not cleaned out the ac system,the ac system will have oil in it,but,the compressor most likely does not have any in it,so pour about 4 to 5 oz in the low side opening on the compressor before installing it,and turn the center nut of the compressor clutch about 8 to 10 times,oil will try and come out the high side,when it does,this will be enough turning.If the system needs more oil,add as needed when freon is put in the system.If the oil is not added to the ac compressor before installing,the compressor could be damaged.Please rate if this was helpful,thank you.
