Installing New Volvo S60 AC Compressor

[cn90]

The 2004 V70 with 155K miles needs a new AC compressor...

1. What brand is everyone using now?
I heard Nissens compressor is now made in China?
How about Valeo?

2. Anyone knows the PNs for O-rings and other odds and ends?

For 2004 V70 2.5T....

Does anyone have the spec for AC compressor replacement?
1. How much PAG oil to add?
2. How much R134a to add?

Thanks!

Your car should have sticker in the engine compartment and if not refer to the link below, My 2001 V70 capacities are the same as in the link.

To get the correct amount of oil in the new compressor you'll need to drain the oil out of the old compressor and add back in the measured amount. The amount you add back into the new compressor depends on what comes out of the old compressor.

If the measured amount of oil drained from the old compressor is less than 2.3 oz you'll need to add back in 2.3 oz to the new compressor.
Drain the oil out of the new compressor and add back in 2.3 oz. The 2.3 oz is the minimum amount of oil needed in the compressor.

If the measured amount of oil drained from the old compressor is greater than 2.3 oz then you'll add this same amount back into the new compressor. The amount of oil that settles in the compressor can vary but it should typically be between 35-50% of the total system oil capacity.

New compressors will likely come with more oil than you'll need so it's important to drain the new compressor oil and fill with the correct amount based on what's drained from the old one. Too much oil will affect the system cooling performance.
After adding oil back into a compressor always spin it a few turns by hand to circulate the oil and make sure it does spin.

page 118 35 oz R134A, 6.75 oz PAG 46 (total system oil capacity)

Actually page 118 says:
- 2001-2006 S60: R134a = 35 oz; PAG-46 oil = 6.00 oz
- 1998-2006 V70: R134a = 35 oz; PAG-46 oil = 6.75 oz

Does anyone know why the difference in PAG-46 spec (but not R134a) for S60 vs V70?

Does V70 have AC vents in the trunk?

PS: The 2006 S60 has a label (open the hood and you will see) saying R134a capacity = 0.7 kg (1.54 lbs).
This is ~ 24.64 oz. I don't know what to believe any longer.
