Filling the A/C system with oil: Notes
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2006 Volvo S80, 2005 Volvo S80, 2004 Volvo S80, 2003 Volvo S80, and 2002 Volvo S80. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
On newer filling/draining/vacuum-pumping stations there is a reservoir for injecting oil. This can be used before filling with refrigerant and after vacuum-pumping without needing to remove the needle valve in the service valve.
NOTE:
Fill with oil before vacuum-pumping.
