WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2012 Porsche Cayman, 2012 Porsche Boxster, 2011 Porsche Cayman, 2011 Porsche Boxster, and 2010 Porsche Cayman. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: Too much refrigerant oil in new air-conditioning compressor.

Risk of damage to air-conditioning components.

→ Do not start engine.

→ Do not tow the vehicle.

Information

New compressors are pressurized and are filled with the required amount of oil for the refrigerant circuit!
The remaining oil quantity in the individual components must therefore be taken into account!
Refrigerant oil from the compressor or refrigerant oil removed by suction from a previously run air-conditioning system may no longer be used (special-category waste)!

If a new compressor is installed, first correct the refrigerant oil quantity in the air conditioning compressor. → Checking Refrigerant Oil In "New" Air Conditioning Compressor
Replace O-rings for the refrigerant lines and wet the new rings with refrigerant oil.
Install air conditioning compressor.
