Part description

This climate pipe is a used original part intended for Citroën C4 and Peugeot 307 cars. It is an important part of the air conditioning circuit, which ensures the conduction of the coolant between the connected parts of the system. When choosing, it is advisable to follow the conformity according to the production numbers, because it is according to them that this type of car part is most often searched for.

The part is suitable for repairs when the original air conditioning pipe is damaged, leaking, mechanically deformed or corroded. For auto mechanics and home repairers, the possibility to replace a defective original part with a corresponding used part without unnecessary modifications is an advantage.

Installation recommendations

In general, it applies to the replacement of the air conditioning pipe that the exact procedure may vary depending on the specific design of the car and the arrangement of the air conditioning system. With the air conditioning circuit, it is always necessary to proceed professionally, cleanly and with regard to the tightness of the system.

1) Before assembly

• Check that the used pipe matches the old part by shape, routing, terminations and product numbers.
• Check whether the pipe is dented, cracked, excessively corroded or otherwise mechanically damaged.
• Check the contact surfaces and the condition of the connection points.
• Compare the fitting and bends of the pipe with the old piece so that there is no tension during assembly.

2) Necessary tools and materials

• Common hand tools
• Remedies for gentle loosening of connections and holders
• Clean work tools without dirt and grease
• Suitable material for cleaning contact surfaces
• New sealing elements if the joint design requires it

3) Step-by-step assembly procedure

1. First safely prepare the vehicle for work and ensure access to the part being changed.
2. Dismantle obstructing covers or parts that prevent convenient access to the air conditioning pipe.
3. Carefully unfasten the original pipe and disconnect its connections so as not to damage downstream components.
4. After removing the old part, compare the two pieces side by side, especially the length, shape, ends and attachment.
5. Thoroughly clean the mating surfaces and check whether there are no dirt or remnants of the old seal left in the connections.
6. If sealing elements are used, fit them in the corresponding design and make sure they are seated correctly.
7. Insert the air conditioning pipe in place without force and without twisting so that it is not under tension after assembly.
8. First lightly seat and align all joints and brackets, then fasten everything one by one.
9. Check that the tube does not rub against the surrounding parts anywhere and that it is in the correct position in the handles.
10. Reinstall all removed covers and related parts.
11. After mechanical assembly, have the air conditioning circuit tested for tightness.
• 4) Post-assembly checks and function verification
  • Check that all connections and brackets are properly seated.
  • Check that the pipe is not touching surrounding parts when the engine is running or vibrating.
  • Check the system for leaks and the correct operation of the air conditioning.
  • After a short run, visually check the connection and fastening again.

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

  • Exchanging a part by appearance – always compare the product numbers and the shape of the line.
  • Impurities in the joints – work cleanly and clean the mating surfaces before assembly.
  • Bad seating in the holders – after fixing, check that the part is not under tension and does not rub anywhere.
  • Underestimating the leak check – after installation, always check that the air conditioning circuit is properly sealed and functioning.

  Reasons why the part is damaged

  • Corrosion of the material caused by age and long-term exposure to moisture.
  • Mechanical damage during previous repair, disassembly or contact with surrounding parts.
  • Vibration and tension in case of bad storage or worn holders.
  • Leaks in joints which can lead to deterioration of the air conditioning function over time.
  • Deformation of the tube caused by improper handling or impact.
