I have had questions about poor cooling and other problems dealing with the AC system after removal of the compressor for repair or replacement.
It is important to measure the amount of oil removed from the compressor if you are not going to flush the complete system and replace all the oil.
The amount of oil removed will give you a clue as to how much is in the system and if your oil was overfilled causing poor cooling AND excessive engine temp while using your AC.
To much oil or refrigerant will cause the condenser to over heat and pass the hot air thru the engine radiator.
The A-6 compressor has a oil pan, oil pick up tube, and oil pump inside, and it's oil level. It is as important as any other oil level in your car as it lubes 4 internal bearings, front seal, and assists in the ring lubrication.
Some compressors (newer design) do not have this system with a oil pan and lube like a 2 stroke engine.
1- you need to know what you removed to see if it was correct, (4 to 6oz.) this will let you or your mechanic know if you need oil attention down stream.
2- If it was overfilled when removed and you are re-installing after repair, and your system seemed OK
before removal, you can now install it with the correct amount.
3- it is possible to remove excess oil while system is charged by cracking the drain plug and letting the excess oil stream out until the refrigerant gas appears.
Bottom line is that it is important to measure the oil and that oil is at right level/amount in compressor at installation.
Some shops that are not familiar with the A-6 have not added oil to the compressors prior to installation and relied on adding a oil charge during the gas charge which will starve the bearings and front seal and cause early failure.
All is in the MANUAL and it will say it much better than I. My point was to make sure the manual is there and the newer mechanics are made aware. Made aware can upset some but you can always hand them a complimentary print out of the pages so they don't need to find the info.
