A/C Compressor, Removing And Installing
Special tools and workshop equipment required
- Torque Wrench 1331 5-50Nm VAG1331
- A/C Service Station VAS6007A
Flush the refrigerant circuit with R134a refrigerant under the following conditions:
In the event of dirt or other contamination in the refrigerant circuit.
If vacuum reading is not maintained on evacuating a leak-free refrigerant circuit (pressure build-up due to moisture in refrigerant circuit).
If the refrigerant circuit has been left open for longer than normal (for example, following an accident).
If pressure and temperature measurements in the refrigerant circuit indicate the likelihood of moisture
In the event of doubt about the amount of refrigerant oil in the circuit.
The A/C compressor must be replaced on account of internal damage (for example, noise or no output).
ELSA contains all information regarding performing repairs on vehicles with air conditioning and working with refrigerant. Refer to A/C System, General Information .
Information on tools for repairs in vehicles with climate control system can be found in ELSA. Refer to Test Requirements .
ELSA contains usage information for the A/C service station. .
Under certain conditions, the dryer bag should no longer be replaced each time the refrigerant circuit is opened. Refer to [For transmission(s) 02E, 09M] Component Location Overview - Electrical Components or [For transmission(s) 02Q] Component Location Overview - Electrical Components in ELSA.
The procedure for flushing with refrigerant R134a is described in ELSA. Refer to Refrigerant R134a Vapor Pressure Table .
-- Extract refrigerant, using an A/C Service Station VAS6007A for example. Only open the refrigerant circuit after doing this.
Removing
-- Note safety precautions. Refer to HANDLING REFRIGERANT .
-- See notes. Refer to WORKING ON THE REFRIGERANT CIRCUIT .
-- Extract refrigerant, for example, using A/C Service Station VAS6007A, only then open the refrigerant circuit. See notes. Refer to OVERVIEW - COMPONENTS OUTSIDE OF PASSENGER COMPARTMENT .
-- Remove the noise insulation under the engine. Refer to RIBBED BELT .
-- Remove the ribbed belts. Refer to REMOVAL AND INSTALLATION .
Vehicles with 2.0L CR engine:
-- Remove the charge air hose. Refer to [For engine(s) CCTA, CBFA] Overview - Charge Air Hose Connections .
-- Remove the intake manifold. REMOVAL AND INSTALLATION
-- Remove the fan shroud. Refer to REMOVAL AND INSTALLATION .
All vehicles
-- Disconnect the connector from the A/C Compressor Regulator Valve -N280-.
Danger due to refrigerant coming out under pressure.
Danger of frost bite to skin and other parts of the body.
- Extract the refrigerant and immediately open the refrigerant circuit after that.
- If the refrigerant was extracted more than 10 minutes in the past and the refrigerant circuit was not opened, extract the refrigerant again. Pressure in the refrigerant circuit is caused by evaporation.
-- Remove the bolts (22 Nm ± 1 Nm) -1- from the A/C compressor and then disconnect the refrigerant pipes from the A/C compressor.
-- Remove the hex bolts (25 Nm) -2- and the A/C compressor.
Installing
Make sure alignment bushings -3- are seated correctly.
-- Install in reverse order of removal.
