A/C COMPRESSOR, REMOVING AND INSTALLING, Vehicles with 3.0L and 3.2L Gas: Installing

WARNING: This page does not describe the selected car, but rather 13 other vehicles, including the 2017 Audi SQ5, 2017 Audi Q5, 2016 Audi SQ5, 2016 Audi Q5, and 2015 Audi SQ5. However, it is still accessible from the selected car via links, so may be relevant.

Install in reverse order of removal. Note the following:

NOTE:

There is a quantity of refrigerant oil in the removed A/C compressor, therefore observe the notes for replacing the A/C compressor. Refer to REFRIGERANT CIRCUIT COMPONENTS, REPLACING and A/C COMPRESSOR, REMOVING AND INSTALLING, Vehicles with 3.0L and 3.2L Gas (Refrigerant R134a, Servicing; Refrigerant Circuit Components, Replacing).

Before installing the A/C compressor. Refer to REFRIGERANT CIRCUIT COMPONENTS, REPLACING (Refrigerant R134a, Servicing; Refrigerant Circuit Components, Replacing).

-- Before tightening the A/C compressor, check seating of both alignment bushings -A- in bracket or A/C compressor -B-.

NOTE:

The alignment sleeves -A- have different styles (different lengths), make sure to use the correct style. .

Ensure bushings -A- are properly seated and contact surfaces are clean. Bushings installed incorrectly and dirty or damaged contact surfaces -C- on the bracket or A/C compressor can lead to alignment irregularities between the A/C compressor and engine. Alignment irregularities over operating time lead to damage to the ribbed belt or A/C compressor.

-- Install bolts -A-, -B- or -C-.

CAUTION:

Depending on the engine and when the vehicle was manufactured, the different bolts have different tightening specifications.

To ensure the correct allocation.
Aluminum bolts (item -A-) only to be used once, replace.
Tightening specification for aluminum bolts (item -A-) 8 Nm +180°
Tightening specification for steel bolts (here -B- and -C-) 25 Nm

-- Tighten bolt -B-, -C- (and bolt -E-).

-- Turn the A/C compressor by hand 10 rotations before installing the ribbed belt on the pulley (to prevent damage to the compressor when it is first switched on).

-- Install the pressure line to the power steering pump. Refer to OVERVIEW - VEHICLES WITH DYNAMIC STEERING, Vehicles with 4-Cylinder TFSI Engine or OVERVIEW - VEHICLES WITH DYNAMIC STEERING, Vehicles with 6-Cylinder FSI Engine .

-- Install the ribbed belt -A-. Refer to INSTALLING for CALB, or INSTALLING for CTUC, CTUB and CTUD .

-- Attach the refrigerant lines to the A/C compressor. Refer to REFRIGERANT LINES, DISCONNECTING AND CONNECTING AT A/C COMPRESSOR .

NOTE:

Coat the O-ring seals lightly with refrigerant oil prior to installation. Refer to REFRIGERANT CIRCUIT SEALS .

Rotating will prevent damage to the A/C compressor when starting the engine for the first from refrigerant oil that may be located in the compression chamber.

After fastening the A/C compressor and installing the refrigerant line, check installation position of refrigerant lines, lines must be engaged in bracket (if installed, depending on engine).

Check refrigerant lines and their bracket to ensure there is enough distance to the other components. Ensure there is also enough distance between belts, bracket and pulley.

-- Evacuate the refrigerant circuit and fill it. 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).

-- Install the remaining removed components.

-- Check the DTC memory for the Climatronic Control Module -- display and control head and erase any displayed malfunctions, if necessary using the Vehicle Diagnostic Tester in the "Guided Fault Finding" function.

-- Operate the A/C system after filling the refrigerant circuit. Refer to A/C SYSTEM, STARTING OPERATION AFTER FILLING REFRIGERANT CIRCUIT .

NOTE:

Observe the information regarding operating the A/C system after filling. Refer to A/C SYSTEM, OPERATING AFTER CHARGING , (Refrigerant R134a, Servicing; A/C System, General Information). After charging the A/C system before activating the A/C system.
