Renault Clio: Compressor - intermediate pipe connecting pipe: Removal - Refitting

F4R or K9K or M4R, 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 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).

K9K

• Remove the intercooler (see Intercooler: Removal - Refitting) (12B, Turbocharging).

• Remove the air deflector.

II - OPERATION FOR REMOVAL OF PART CONCERNED

• Remove:
  • the engine tie-bar (1) (see Right-hand suspended engine mounting: Removal - Refitting) (19D, Engine mounting),
  • the nut (2) from the pipe retaining clip on the body.
• Uncouple the expansion valve - intermediate pipe connecting pipe from the compressor - intermediate pipe connecting pipe using the (Mot. 1410) at (3).
• Fit plugs into the openings.

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 circuit 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 (4) 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 compressor - intermediate pipe 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

• Fit the connecting pipe to the compressor.
• Refit the bolt (5) securing the connecting pipe on the compressor.
• Tighten the connecting pipe bolts.

• Couple the expansion valve - intermediate pipe connecting pipe to the compressor - intermediate pipe connecting pipe at (6).
• Refit the body mounted pipe retaining clip nut (7).

III - FINAL OPERATION

• Refit the air deflector.

K9K

• Refit the intercooler (see Intercooler: Removal - Refitting) (12B, Turbocharging).

• Refit the engine tie-bar (see Right-hand suspended engine mounting: Removal - Refitting) (19D, Engine mounting).
• 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).
