V6 TDI
A/C Compressor From Bracket
Hex Ball Socket TORX TB 60 (T40087)
Special tools, testers and auxiliary items required
•
Compressor driven by a ribbed belt
• You can remove and reinstall the A/C compressor in vehicles with a 6 cylinder TDI engine. The TDI engine can be removed and installed from the bracket without opening the refrigerant lines.
• Do not discharge the refrigerant circuit to remove the bracket, do not remove refrigerant hoses and lines from A/C compressor.
• Do not unfasten refrigerant pipes and corresponding clamps.
• Secure the A/C compressor after removal with a wire, for example, on the vehicle, do not allow it to hang by the refrigerant lines.
• Before removing, mark direction of operation of ribbed belt with chalk or felt-tipped pen. Reversing the direction of rotation of a run-in belt can destroy the belt.
• Different compressors may be installed depending on the engine and country. Refer to the Electronic Parts Catalog (ETKA).
Removing
Proceed as follows:
- Switch off the ignition.
- Remove front noise insulation.
- Mark the direction of the operation of the ribbed belt - A -.
- To remove the ribbed belt, swivel the tensioner using (T40087) in - the direction of arrow -.
- Remove the ribbed belt from the ribbed belt pulley on the compressor and release the tensioner.
- Disconnect the power steering pump from the bracket (this is not always necessary on vehicles with a flexible power steering pressure line. Move it to the side and secure it on the engine with wire.
• Make sure not to twist, bend or pull the lines to the vane pump.
• There are different versions (stiff or flexible) of the power steering pump pressure line.
- Disconnect the electrical connector - A -.
- Remove the A/C compressor bolt - B -.
• There is an opening - C - in subframe - A - for removing rear screw - B -.
Risk of damaging refrigerant lines and hoses.
• Do not stretch, kink or bend refrigerant lines and hoses.
- Remove the A/C compressor and swivel it away from the engine without pulling or bending the refrigerant pipes
- Fasten the A/C compressor to the vehicle (for example, with a wire) without pulling or bending the refrigerant hoses.
• If the A/C compressor cannot be swiveled away enough from the engine, then the A/C compressor must be removed. Refer to => [ Compressor ] Compressor.
Installing
Installation is done is reverse order, observe the following:
- Before tightening the A/C compressor, check seating of both alignment bushings - A - in bracket or A/C compressor - B -.
• The alignment sleeves - A - have different styles (different lengths), make sure to use the correct style. Refer to Electronic Parts Catalog (ETKA).
• Ensure bushings - A - are properly seated and contact surfaces are clean. Sockets 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.
- Tighten the bolts - arrows - (tightening specification: 25 Nm).
- Connect electrical connector - 1 - on A/C Compressor Regulator Valve (N280).
- Mount the ribbed belt onto the ribbed belt pulley.
• After fastening the A/C compressor, 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.
- Check the event memory of the front A/C display control head, the Climatronic control module (J255) , and erase any displayed malfunctions using the (Vehicle diagnostic tester) in the "Guided Fault Finding" function.
