A/C COMPRESSOR, REMOVING AND INSTALLING, Vehicles with 3.0L and 3.2L Gas: Removing
-- Turn off the ignition.
-- Discharge the refrigerant circuit. Refer to USING SERVICE STATION . For additional information, refer to OVERVIEW - REFRIGERANT CIRCUIT, NOT OPENING THE REFRIGERANT CIRCUIT, VEHICLES WITHOUT HIGH VOLTAGE SYSTEM and OVERVIEW - REFRIGERANT CIRCUIT, OPENING THE REFRIGERANT CIRCUIT, VEHICLES WITHOUT HIGH VOLTAGE SYSTEM (Refrigerant R134a, Servicing; Refrigerant Circuit, Using Service Station).
Depending on the allocation of the service connection to the refrigerant line and vehicle version, it may be necessary to remove the left additional reinforcement on the tower brace so that the service coupling of the A/C service station can be connected (for example, on the Audi Q5). Refer to OVERVIEW - SUSPENSION STRUT WITH MOUNTING BRACKET, SHOCK ABSORBER FORK, UPPER CONTROL ARM AND TOWER BRACE and USING SERVICE STATION . For additional information, refer to OVERVIEW - REFRIGERANT CIRCUIT, NOT OPENING THE REFRIGERANT CIRCUIT, VEHICLES WITHOUT HIGH VOLTAGE SYSTEM and OVERVIEW - REFRIGERANT CIRCUIT, OPENING THE REFRIGERANT CIRCUIT, VEHICLES WITHOUT HIGH VOLTAGE SYSTEM (Refrigerant R134a, Servicing; Refrigerant Circuit, Using A/C Service Station).
-- Remove the front noise insulation. Refer to FRONT NOISE INSULATION .
-- Remove the bolts -1- and nuts -3- and remove the left longitudinal brace -2-. Refer to OVERVIEW - LOCK CARRIER .
-- Remove the left front wheel and left front wheel housing liner. Refer to OVERVIEW - FRONT WHEEL HOUSING LINER .
-- Mark the running direction of the ribbed belt -A-. Refer to OVERVIEW - RIBBED BELT DRIVE for CALB, OVERVIEW - RIBBED BELT DRIVE for CTUC, CTUB and CTUD .
-- Remove the ribbed belt -A-. Refer to OVERVIEW - RIBBED BELT DRIVE for CALB, or RIBBED BELT, REMOVING AND INSTALLING for CTUC and CTUD, .
-- If equipped, clamp off the supply line (suction hose) to the power steering pump -B- using the Hose Clamps up to 25 mm Diameter 3094. Refer to appropriate power steering components in OVERVIEW - VEHICLES WITH DYNAMIC STEERING, Vehicles with 4-Cylinder TFSI Engine or OVERVIEW - VEHICLES WITH DYNAMIC STEERING, Vehicles with 6-Cylinder FSI Engine .
-- If necessary, remove the pressure line -C- from the power steering pump -B-. Refer to appropriate power steering components in OVERVIEW - VEHICLES WITH DYNAMIC STEERING, Vehicles with 4-Cylinder TFSI Engine or OVERVIEW - VEHICLES WITH DYNAMIC STEERING, Vehicles with 6-Cylinder FSI Engine .
When moving the pressure line to the side, be sure not to bend, twist or pull the line to the power steering pump.
The power steering pump -B- is not loosened from the bracket when removing the A/C compressor.
The pressure line and power steering pump are only installed on vehicles without electromechanical power steering. Refer to appropriate power steering components in POWER STEERING PUMP, REMOVING AND INSTALLING, VEHICLES WITH DYNAMIC STEERING, Vehicles with 6-Cylinder FSI Engine or POWER STEERING PUMP, REMOVING AND INSTALLING, VEHICLES WITHOUT DYNAMIC STEERING, Vehicles with 6-cylinder FSI Engine for over views .
The pressure line to the vane pump -C- (see Fig 2) is secured to the A/C compressor by the bracket with the bolt -C- (see Fig 3).
-- Remove the refrigerant lines from A/C compressor. Refer to REFRIGERANT LINES, DISCONNECTING AND CONNECTING AT A/C COMPRESSOR .
The refrigerant lines are removed from the top.
On vehicles with a gasoline engine and dynamic steering (depending on where the intake hose is installed on the power steering pump), first loosen the A/C compressor from the bracket and then remove the refrigerant lines from the A/C compressor. Refer to REFRIGERANT LINES, DISCONNECTING AND CONNECTING AT A/C COMPRESSOR .
-- Disconnect the connector -A-.
-- Remove bolt -B- (and bolt -C-).
The bolt -C- was already removed on vehicles with a power steering pump when the pressure line to the power steering pump was loosened.
The pressure line and power steering pump are only installed on vehicles without electromechanical power steering. Refer to appropriate power steering components in POWER STEERING PUMP, REMOVING AND INSTALLING, VEHICLES WITH DYNAMIC STEERING, Vehicles with 6-Cylinder FSI Engine or POWER STEERING PUMP, REMOVING AND INSTALLING, VEHICLES WITHOUT DYNAMIC STEERING, Vehicles with 6-cylinder FSI Engine for over views .
This illustration shows the A/C compressor in a vehicle equipped with an After-Run Coolant Pump -V51- (not installed on all versions). Depending on the vehicle equipment level, it may be necessary to drain the coolant and remove the After-Run Coolant Pump -V51- so that the A/C compressor can be removed (for draining the coolant and removing the After-Run Coolant Pump -V51-. Refer to COOLANT PUMP/THERMOSTAT for CALB, or COOLANT PUMP/THERMOSTAT for CTUC and CTUD ).
Depending on the version of the A/C compressor and of the vehicle (different coolant fans, radiator and hoses to the After-Run Coolant Pump -V51-), it may also be necessary to bring the lock carrier into the service position (so that the A/C compressor can be pivoted out downward). Refer to SERVICE POSITION, PERFORMING AND RESETTING .
Information for the service position of the lock carrier:
- When the bolts -A- are first removed, and after bolts -A- are removed, mark the position of the lock carrier -B-, for example with a water resistant marker on the longitudinal member -C- (through the left and right hole) so that it can be installed exactly in the same position.
- When both bolts -D- are removed and then longer bolts -E- (for example bolts M10 x 100) are installed, the lock carried can be moved approximately 60 mm forward after the bolts -F- are removed.
- Using the sleeves -G- (or a suitable pad approximately 60 mm long), secure the lock carrier -C- from sliding back.
-- Remove the bracket -D-.
-- Remove the bolt -E-.
-- Remove the A/C compressor -F- from the bracket, pull it forward and remove it downward.
