D4F or K4J or K4M, and AIR CONDITIONING or CLIMATE CONTROL

IMPORTANT

To avoid all risk of damage to the systems, apply the safety and cleanliness instructions and operation recommendations before carrying out any repair:

• (see 62A, Air conditioning, Air conditioning: Precautions for the repair, 62A-1),
• (see Vehicle: Precautions for the repair) (01D, Mechanical introduction).

REMOVAL

I - REMOVAL PREPARATION OPERATION

• Position the vehicle on a two-post lift (see Vehicle: Towing and lifting) (02A, Lifting equipment).
• Drain the refrigerant circuit using the refrigerant charging station (see 62A, Air conditioning, Refrigerant circuit: Draining - Filling, 62A-10).
• Disconnect the battery (see Battery: Removal - Refitting) (80A, Battery).
• Remove:
  • the windscreen wiper arms (see Windscreen wiper arm: Removal - Refitting) (85A, Wiping - Washing),
  • the scuttle panel grille (see Scuttle panel grille: Removal - Refitting) (56A, Exterior equipment),
  • the scoop under the scuttle panel grille (see Scoop under the scuttle panel grille: Removal - Refitting) (56A, Exterior equipment),
  • the front wheels (see Wheel: Removal - Refitting) (35A, Wheels and tyres),
  • the front wheel arch liners (see Front wheel arch liner: Removal - Refitting) (55A, Exterior protection),
  • the front bumper (see Front bumper: Removal - Refitting) (55A, Exterior protection).

• Move the air intake sleeve to one side (1).

II - OPERATION FOR REMOVAL OF PART CONCERNED

• Remove the mountings from the bulkhead soundproofing.
• Lift away the bulkhead soundproofing.
• Remove the connecting pipe bolt (2) on the expansion valve.
• Remove the connecting pipe from the expansion valve.

WARNING

In order to avoid any refrigerant leaks, do not damage (deform, twist, etc.) the pipe.

• Plug the openings on the connecting pipe and expansion valve.

WARNING

To prevent moisture from entering the system, place plugs on the cold loop components which are open to the air.

Note: Use blanking plugs for the fuel circuits with part no. 77 01 208 229 or 77 01 476 857 to plug any openings exposed to the open air. They must be clean. Do not use any which have already been used to plug a fuel circuit.

• Remove the bolt (3) securing the connecting pipe on the compressor.
• Remove the connecting pipe from the compressor.

WARNING

In order to avoid any refrigerant leaks, do not damage (deform, twist, etc.) the pipe.

• Plug the openings on the connecting pipe and compressor.

• Remove:
  • the connecting pipe retaining clip nut (4),
  • the compressor - expansion valve connecting pipe.

REFITTING

I - REFITTING PREPARATION OPERATION

WARNING

Do not remove the blanking plugs from each component until the last moment.

Also, do not remove the components from their packaging until they are to be fitted to the vehicle.

• Clean the surface and seal of the pipe using ENGINE CLEANER (see Vehicle: Parts and consumables for the repair) (04B, Consumables - Products).

• Use a compressed air nozzle to blow on the surface and the seal of the connecting pipe.
• Lubricate the surface of the connecting pipe and the seal with air conditioning oil (see 62A, Air conditioning, Air conditioning: Parts and consumables for the repair, 62A-2).
• Remove the blanking plugs.

II - REFITTING OPERATION FOR PART CONCERNED

• Refit:
  • the compressor - expansion valve connecting pipe,
  • the connecting pipe retaining clip nut (5),

• Fit the connecting pipe union to the compressor.
• Refit the bolt (6) securing the connecting pipe on the compressor.
• Tighten the compressor connecting pipe bolt.

• Fit the connecting pipe to the expansion valve.
• Refit the connecting pipe bolt (7) on the expansion valve.
• Tighten the expansion valve connecting pipe bolt.
• Fit the bulkhead soundproofing.
• Refit the bulkhead soundproofing mountings.

III - FINAL OPERATION

• Fit the air intake sleeve (8).
• Connect the battery (see Battery: Removal - Refitting) (80A, Battery).
• Fill up the refrigerant circuit using the refrigerant charging station (see 62A, Air conditioning, Refrigerant circuit: Draining - Filling, 62A-10).

Note: A summary table gives the quantities of refrigerant in the system according to the engine type (see 62A, Air conditioning, Air conditioning: Parts and consumables for the repair, 62A-2).

• Check that the air conditioning system is operating correctly (see 62A, Air conditioning, Air conditioning: Check, 62A-6).
• Check for leaks (see 62A, Air conditioning, Refrigerant circuit: Check, 62A-9).
• Refit:
  • the front bumper (see Front bumper: Removal - Refitting) (55A, Exterior protection),
  • the front wheel arch liners (see Front wheel arch liner: Removal - Refitting) (55A, Exterior protection),
  • the front wheels (see Wheel: Removal - Refitting) (35A, Wheels and tyres),
  • the scoop under the scuttle panel grille (see Scoop under the scuttle panel grille: Removal - Refitting) (56A, Exterior equipment),
  • the scuttle panel grille (see Scuttle panel grille: Removal - Refitting) (56A, Exterior equipment),
  • the windscreen wiper arms (see Windscreen wiper arm: Removal - Refitting) (85A, Wiping - Washing).
