Climate pipe Citroën C5 II Peugeot 407 9659576280 647773

Description

Air conditioning coolant pipe for CITROEN C5 X7 and PEUGEOT 407

Part description

This climate pipe (air conditioning coolant pipe) is intended for the repair of malfunctioning or leaking air conditioning. A used original part from the Stellantis (Citroën/Peugeot) concern is a suitable choice for replacement after mechanical damage to pipes, corrosion or after intervention in the engine compartment, when it is necessary to restore the tightness of the air conditioning circuit.

Installation recommendations

Generally/typically applies to the replacement of air conditioning coolant pipes (the exact procedure may vary depending on the specific design of the car and pipe routing).

1) Before assembly

• Compare the new part with the old one: numbers 9659576280 / 647773, tube shape, bends, holders/grips and end type.
• Check the condition of the mating surfaces and threads/fastenings for deformation.
• Verify that the pipe is not dented, cracked or severely corroded and that the ends are not dirty.

2) Necessary tools and materials (in general)

• Basic set of keys and sockets, or side keys for pipe couplings
• Suitable cleaning agents for degreasing contact surfaces
• New seals/O-rings for joints (if used) as per design
• Protective gloves and goggles

3) Step-by-step assembly procedure

1. Secure the vehicle against movement and allow surrounding components to cool.
2. If necessary for access, remove obstructing covers/parts in pipe routing area.
3. Clean around the connections so that dirt does not enter the circuit.
4. Carefully release the fasteners and disconnect the pipes from the connected parts of the circuit (according to the design of the connections).
5. Remove the old pipe and check that there are no old gaskets left on the mating surfaces.
6. Clean the mating surfaces and prepare the joints for assembly.
7. Install the pipe in its original position and first “seat” it in the holders without force (it must not be in tension).
8. When installing gaskets/O-rings, use the correct type for the joint and ensure they are clean and undamaged.
9. Connect the pipe ends and tighten the fasteners evenly so that the joint fits properly.
10. Secure all mounts/holders so that the pipe does not rub against surrounding parts.
11. Put back all disassembled covers/parts.

• 4) Post-assembly checks and test drive/function verification

  • Perform a visual check that the pipe does not rub anywhere, is not in contact with sharp edges and is properly attached.
  • Verify connections for leaks and A/C function per standard A/C system service procedure.
  • After a short ride, recheck the fitment and any signs of leakage around the connections.

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

  • Exchanging pipes for a similar type → always compare the shape and codes 9659576280 / 647773.
  • Reusing old gaskets → typically leads to leakage; use appropriate new seals according to design.
  • Impurities in contact surfaces → clean carefully before connection, work in cleanliness.
  • Pipeline in tension / poor attachment → first place correctly in the holders, then tighten the connections.

  Reasons why the part is damaged

  • Corrosion of pipes due to the environment (moisture, salt, dirt) and long-term operation.
  • Mechanical damage (impact, contact with other parts, abrasion on holders/covering).
  • Vibration and tension in the case of incorrect attachment or after previous unprofessional assembly.
  • Damage to joints and seals during disassembly/assembly or due to aging of sealing elements.
