Oil return when replacing compressor:
Drain the old compressor of oil, and measure the amount.
Drain the new compressor of oil (the amount may be below specified value since it is not possible to drain all oil from the compressor).
Use the table below to fill the new compressor with the right amount of oil.
Caution! When installing completely new system: Check that there is oil in the compressor. The other components should contain no oil.

Replace the receiver drier in the following cases:
when replacing the compressor (e.g., compressor breakdown)

when replacing any air conditioning (A/C) component outside the warranty period.
Filling the A/C system with oil
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.
Filling with PAG oil
When replacing pipes/hoses, oil can be filled through the service valve.
When filling the vehicle with PAG oil (for P/N see spare parts catalog), carry out the following:
Remove the needle valve in the service valve using valve tool 951 1204 REMOVAL TOOL See: Tools and Equipment/951 1204 Removal Tool.
Use the filling syringe (without plastic hose) supplied with the unit to top up the oil. Clean the syringe to avoid the possibility of mixing different types of
