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.
Replacing the receiver drier
Replace the receiver drier in the following cases:
-
when replacing the compressor (e.g., compressor breakdown)
-
refrigerant leakage, where nearly 100% has leaked out of the system (the system has no pressure)
-
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.
