Technical Information
- Manufacturer: Stellantis (Citroën / Peugeot)
- Model: Citroën C5 II, Peugeot 407
- Product Codes: 9650885580, 6460LP
- Other Numbers: NFP
Function And Application
This pipe is part of the vehicle’s air conditioning refrigerant circuit. Its primary function is to route refrigerant between AC components (compressor, condenser, evaporator/receiver-drier or expansion valve) while withstanding system pressures and thermal cycles. Correct fitment ensures leak-free connections and maintains factory cooling capacity.
How To Replace (Overview)
- Recover Refrigerant: Safely recover refrigerant using certified recovery equipment according to local regulations.
- Access And Remove: Locate the damaged pipe following factory routing. Remove retaining clamps or brackets and disconnect fittings. Keep track of all clamps and fasteners.
- Replace Seals: Always replace O-Rings/seals at each connection with new, correctly sized parts and lubricate them with the correct refrigerant oil.
- Install New Pipe: Fit the replacement pipe, secure clamps/brackets to factory positions, and tighten fittings to the manufacturer’s guidance.
- Evacuate And Recharge: Evacuate the system to the required vacuum, perform a leak check, then recharge with the correct refrigerant (original systems for these models use R134a) and the specified lubricant amount.
- Test Operation: Run the AC, verify pressures and temperatures, and inspect all joints for leaks under operating conditions.
Installation And Recommendations
- Perform Refrigerant Recovery: Use certified recovery/recycling equipment—do not vent refrigerant to atmosphere.
- Replace O-Rings: Install new O-Rings at every disconnected joint; use the correct type and lubricant (PAG oil where specified).
- Inspect Associated Components: Check receiver-drier/desiccant, expansion valve/orifice and compressor for contamination; if the system is contaminated, replace the receiver-drier and flush the system as required.
- Use Correct Tools: AC manifold gauge set, vacuum pump, leak detector and torque tools improve reliability of the repair.
- Follow Safety Rules: Work in a well-ventilated area and wear protective equipment. Comply with local environmental rules for refrigerant handling.
Why This Part Typically Fails
- Corrosion: Metal pipes and connection points corrode over time, especially in regions with road salt or high humidity, leading to leaks.
- Mechanical Damage: Impact from road debris or improper routing/installation can dent or crack the pipe.
- O-Ring Deterioration: Seals age, harden or become brittle, causing leaks at connection points.
- Vibration And Fatigue: Constant vibration and thermal cycling cause stress at joints and bends, eventually producing leaks.
Compatibility And Notes
Fits Citroën C5 II and Peugeot 407 models that use the referenced part numbers. Always verify the part number (9650885580 / 6460LP) against the unit you remove to ensure correct routing and connector type. Suitable for professionals and competent DIY technicians familiar with AC system service.
