Removing and installing compressor - GT3: Installation

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2005 Porsche 911, 2004 Porsche 911, 2003 Porsche 911, 2002 Porsche 911, and 2001 Porsche 911. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: New compressors are pressurised 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).

Use fastening screws from the new compressor. Replace O-rings and wet the new rings with refrigerant oil.
Do not remove the plugs for the lines and compressor connection until shortly before installation.
Install compressor with lines.
NOTE: There is a spacer sleeve between the compressor and the console. This spacer sleeve must be glued onto the compressor with instant adhesive before installation. Engage electrical connection and install compressor with fastening screws.
Install expansion tank with hydraulic pump and fasten oil filler necks to holder.
