Removal and installation of compressor K / V
Petrol models Details of installation of compressor K / V on petrol models  | - Make discharging the air conditioning system in a specialized service stations.
- Remove supporting the fan assembly (see. Section Removal and installation of auxiliary fan assembly).
- Remove the condenser K / V (see. Section Removal and installation of the capacitor system K / V).
- Remove the radiator cooling system (see. Section Removal and installation of the radiator).
- Remove the accessory drive belt (see chap. Engine).
- Disconnect the connector (A9x1) electrical compressor K / V.
- Remove the screws (2) and remove the front (4) and pressure (3) lines of a refrigerator path - immediately shut off the open ends of lines and couplings to prevent the ingress of moisture into the channel, make a replacement O-rings (5).
- Remove the fastening screws (1) and remove the compressor assembly (A9) system K / V.
- Remove the receiver-dryer assembly (see. Section Removal and installation of receiver-dryer) - the receiver must be replaced without fail. Do not forget to plug the open ends of the refrigerator lines.
- Installation is in the reverse order
 | Screws (1) must be tucked into place before installing the compressor. |
- Make sure that the system has been added necessary (according to the number of replaced components - see. the amount of refrigerant oil. Do not forget to grease before installing the new O-rings with compressor oil.
- Start the engine and let it run at idle speed for about 4 minutes with the maximum cooling capacity to air conditioning, - the temperature of air supplied to the cabin through the vents of the central duct in the instrument panel should not fall below the value of + 5 ?� C.
- Make sure there are no signs of leakage from the refrigerator path.

Diesel models G270 CDI (M612) Details of installation of compressor K / V on diesel models with engine M612  | |
| - Drain the cooling system, in the conditions of a specialized service station make a discharge air conditioning system.
- Remove the receiver-dryer assembly (see. Section Removal and installation of receiver-dryer), - replacement of the receiver should be carried out every time after opening the refrigerator path. Do not forget to plug the open ends of the refrigerator lines.
- Remove the radiator cooling system (see. Section Removal and installation of the radiator).
- On appropriately staffed models (code H12), remove the additional heater assembly (see. Section Removal and installation of auxiliary heater STH (with appropriate equipment)).
- Remove the accessory drive belt (see chap. Engine).
- Remove the left sleeve tract pressurization system.
- Disconnect the connector (A9x1) electrical compressor K / V.
- Remove the screws (1 and 3) and remove the front (2) and pressure (4) of the line refrigerator path - immediately shut off the open ends of lines and couplings to prevent the ingress of moisture into the channel, make a replacement O-rings.
- Remove the mounting bolts (5) and remove the compressor assembly (A9) system K / V.
- Installation is in the reverse order.
| When installing a new compressor slightly relieve the pressure of it, complete with the compressor and the expansion valve is replaced, the front line and pressurized with sealing rings. |
- Adjust the level of refrigerant in the compressor, in conclusion, make sure the components of refrigeration and cooling (model code H12) tract for signs of leaks.

G400 CDI (M628) Details of installation of compressor K / V on diesel models with engine M628  | - Open the hood.
- Drain the cooling system, in the conditions of a specialized service station make a discharge air conditioning system.
- Remove the receiver-dryer assembly (see. Section Removal and installation of receiver-dryer), - replacement of the receiver should be carried out every time after opening the refrigerator path. Do not forget to plug the open ends of the refrigerator lines.
- Remove the condenser K / V (see. Section Removal and installation of the capacitor system K / V).
- On appropriately staffed models (code H12), remove the additional heater assembly (see. Section Removal and installation of auxiliary heater STH (with appropriate equipment)).
- Remove the accessory drive belt (see chap. Engine).
- Remove the lower left path duct pressurization.
- Disconnect the connector (A9x1) electrical compressor K / V.
- Remove the screws (1) and remove the front (11) and discharge (10) of the line refrigerator path - immediately shut off the open ends of lines and couplings to prevent the ingress of moisture into the channel, make a replacement O-rings.
- Remove the fixing bolts (2 and 2a) and pulling up, remove the compressor assembly (A9) system K / V.
- Installation is in the reverse order.
| When installing a new compressor slightly relieve the pressure of it, complete with compressor replaced by the input and pressure lines with sealing rings. |
- Adjust the level of refrigerant in the compressor, in conclusion, make sure the components of refrigeration and cooling (model code H12) tract for signs of leaks.
