How much PAG 46 On AC compressor/drier change?
I think my parts list is complete to get this AC swap done. But I have no idea how much PAG46 I'm supposed to use! I know I'm supposed to measure how much oil comes out of the old compressor and put that amount in the new one. But I also know there's some in the receiver drier that I'm replacing. I can't find how much to add to compensate for new dessicant in the drier? Also, I plan to pull vacuum on the AC system to do a proper refill especially given how humid Florida is right now. Does pulling vacuum suck any oil out of the system I need to compensate for as well? I haven't done an AC system since my Camaro's R134a conversion back in 2001, so I don't really remember anything about it and learning from scratch. Thanks! :-)

I think the E53 X5 "may" be a bit more than E39 5-series.
I replaced the AC compressor on my 1998 528i at 160K miles and wrote a DIY here... DIY: 1998 BMW 528i 160K Replacing AC Compressor https://www.bimmerfest.com/threads/d...ressor.924320/

- The vacuuming process does not remove much PAG oil.
Probably nothing. - Most of the PAG oil is in the compressor anyway. Some compressor comes prefilled and some leaked PAG oil during shipment. - Best is to drain all the PAG oil out of the new compressor and fill it using info in this thread... https://xoutpost.com/bmw-sav-forums/...ll-volume.html

It's odd that AllData also doesn't specify the type/quantity of compressor oil.
You do need 430-450g of R134a. |
