Removing and installing the compressor: Installation
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2004 Porsche Boxster, 2003 Porsche Boxster, 2002 Porsche Boxster, 2001 Porsche Boxster, and 2000 Porsche Boxster. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
- New compressors are under pressure 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.
- First, open the cap on the high-pressure side and relieve the pressure from the compressor (A).
- Open the oil filler screw (B) on the compressor.
- Empty approx. 80 cm3
of refrigerant oil out of the compressor and into a measuring glass. The remaining quantity of oil (approx. 120 cm3
) remains in the compressor.NOTE:
- 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).
- Tightening torque for the compressor fastening screws on the engine (screws M8): 28 Nm
- Tightening torque for refrigerant line (screws M8 x 32): 23 Nm Use fastening screws from the new compressor. Replace O-rings and wet with refrigerant oil.
- Do not remove the plugs for the lines and compressor connection until shortly before installation.
- Tightening torque for oil filler screw (M10 x 1): 26-36 Nm Always replace the sealing ring.
