Commonly searched by part number 1606380480, the pipe restores correct refrigerant routing in the vehicle climate system and helps eliminate leaks or pressure loss that reduce cooling performance. Designed with professional fitment and everyday workshop replacement in mind, it is suitable for auto technicians and competent DIY mechanics familiar with AC system service.
Technical Information
- Manufacturer: Peugeot / Citroën (Stellantis)
- Model: Peugeot 4007; Citroën C-Crosser 2.2 HDi
- Product Codes: 1606380480
- Additional Numbers: N/A
Function and Application
The air conditioning pipe routes refrigerant between climate system components, providing a sealed path for the refrigerant and maintaining system pressure. Pipes of this type often incorporate metal tubing, flexible sections, fittings and O-ring seals. A leak or blockage in the pipe directly reduces cooling efficiency and can lead to compressor overload or failure if left unaddressed.
Replacement Guide
Replacing the AC pipe requires correct tools and adherence to safety procedures. Typical workshop steps:
- Recover refrigerant using certified recovery equipment before opening the system.
- Remove any protective covers or underbody panels to access the pipe and fittings.
- Loosen and remove the pipe fittings, noting the position and orientation for correct refitment.
- Replace all associated O-rings and seals with new items lubricated with the correct compressor oil.
- Install the new pipe, tighten fittings to the manufacturer torque values, and ensure secure routing to avoid contact with moving parts or hot surfaces.
- Evacuate the system with a vacuum pump, perform a leak test, then recharge with the correct refrigerant and oil specification.
- Verify operation and cooling performance after service.
Installation Recommendations
Always Use Proper Protective Equipment. Replace O-Rings And Seals When Installing A New Pipe. Lubricate O-Rings With The Correct Compressor Oil To Ensure A Reliable Seal. Torque Fittings To Spec And Avoid Over-Tightening. Perform Vacuum And Leak Tests After Installation. If Compressor Failure Was The Cause Of Contamination, Inspect And Service Or Replace The Compressor And Flush System As Required.
Common Failure Reasons
Air conditioning pipes most often fail due to corrosion, chafing against other components, damage from road debris, degraded rubber/flex sections, or failing O-ring seals at the connections. Thermal cycling and vibration can also loosen fittings over time, leading to slow leaks that gradually reduce cooling performance. Prompt replacement of a leaking pipe prevents moisture ingress and further damage to the compressor and other system components.
Who Should Fit This Part
Recommended For Professional Workshops And Skilled DIYers Comfortable Working On Vehicle Air Conditioning Systems. Because AC Service Requires Proper Recovery, Evacuation And Recharge Procedures, Use Of Certified Equipment Is Recommended To Ensure Safety And Compliance.
