Climate pipe Citroen Peugeot 9650629880 6460NC

Description

Air conditioning pipe for Citroen C4 and PEUGEOT 307 cars with 2.0i engine

Part description

This climate pipe is intended for conducting refrigerant in the air conditioning system. If you are dealing with a refrigerant leak, line damage or corrosion, replacing the pipe is often the fastest way to get a fully functional air conditioner again without unnecessary improvisations. Thanks to the clearly given codes, you can easily find the part even by the number that mechanics normally use when ordering.

Suitable for Citroën C4 and Peugeot 307 cars (according to the documents).

Installation recommendations

Generally/typically for air conditioning pipe replacement, the work requires proper procedure for the air conditioning circuit and equipment for suction/supply of refrigerant. The exact steps may vary depending on the specific car design and pipe routing.

1) Before assembly

• Compare the new and original pipe: shape, length, bends, type of ends and attachment.
• Check the threads and the mating surfaces of the terminals for tears or creases.
• Check the condition of the pipe for cracks, dents and corrosion in the places of the brackets.

2) Necessary tools and materials (in general)

• Common hand tools (ratchet, extensions, keys, screwdrivers)
• Suitable equipment for air conditioning service (refrigerant extraction/filling)
• Cleaning agent for degreasing contact surfaces, clean rags
• New O-rings/O-rings if used in the joint

3) Step-by-step assembly procedure

1. Secure the vehicle against movement and allow the engine to cool.
2. Have the air conditioning circuit expertly vacuumed (this is typically required before disconnecting the circuit).
3. Get access to the pipe (removal of covers/lines according to the specific car design).
4. Clean around the connections so that dirt does not enter the circuit.
5. Carefully loosen and disconnect the ends of the tube (without prying through the contact surfaces).
6. Undo the tube holders/mounts and remove the old part.
7. Check the counter parts (butting surfaces, flanges) for damage.
8. Mount the tube in the brackets and seat it in the correct position without tension.
9. Connect the ends, make sure the mating surfaces are clean and the gasket is properly seated (if used).
10. Tighten the connections adequately and check that the wiring does not rub anywhere or touch hot/sharp parts.
11. Evacuate and then fill the air conditioner according to the procedure corresponding to the air conditioning service.
• 4) Post-assembly checks and test drive/function verification
  • Verify the system for leaks (typically a leak check after filling).
  • Check the operation of the air conditioner and the stability of the cooling system at idle and at high speeds.
  • After a short ride, visually check the connections and fit of the tube again.

  5) The most common assembly mistakes + how to avoid them

  • Exchanging the tube (different shape/ends) → always compare 1:1 and follow the codes 9650629880 / 6460NC.
  • Impurities in the circuit → before disconnecting, clean the surroundings of the connections, work in cleanliness.
  • Poorly seated or old gasket → check the gasket and contact surfaces, possibly replace the gasket.
  • Line tension / contact with a sharp edge → correct seating in the brackets, checking clearances after assembly.

  Reasons why the part is damaged

  • Corrosion (especially in attachment points and in places exposed to moisture and salt).
  • Vibration and tension in the case of poor attachment or after hitting surrounding parts.
  • Mechanical damage (impact, contact with a sharp edge, improper disassembly).
  • Leaks at the joints due to wear of the seals or deformation of the contact surfaces.
