Installing compressor
| CAUTION | Risk of damaging the air-conditioning compressor. |
> The engine must not be started until the air-conditioning system has been filled.
Note. 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)!
1. If a new compressor is installed, first correct the refrigerant oil quantity in the air-conditioning compressor. > 873419 Removing and installing compressor - chapter on "Checking"
2. Replace O-rings for the refrigerant lines and wet the new rings with refrigerant oil.
3. Do not remove the plugs for the lines and compressor connection until shortly before installation.

4. Connect the lines and secure with the fastening screws -1, 2-. --> Tightening torque: 20 (15 ftlb.) Nm --> Tightening torque: 20 (15 ftlb.) Nm. see scheme 91
5. Guide air-conditioning compressor through the rear wall opening and place in installation position.
6. Clip in refrigerant hoses -1- and -2- between body and intake-air distributor. see scheme 92
7. Clip in connector for air-conditioning compressor supply line and clip connector housing into the holder provided.
8. Screw in front Torx screws for air-conditioning compressor (M8 x 90) -1- and -2-. see scheme 93
9. Screw in rear Torx screw for air-conditioning compressor (M8 x 120) -1- and tighten all three screws for air-conditioning compressor. --> Tightening torque: 23 (17 ftlb.) Nm. see scheme 94
10. Position power-steering reservoir. Lock bayonet lock -arrow- on power-steering reservoir. see scheme 95
11. Replace the quantity of Pentosin removed during removal with new Pentosin and pour this into the power-steering reservoir.
12. Turn the tensioning roller clockwise using a ring wrench (a/f 24), position the drive belt and then tension it.
