This service part restores proper refrigerant flow inside the air conditioning circuit, helping to recover full cooling performance and eliminate leaks. Ideal for professional workshops and experienced DIY mechanics who look up parts by reference number — listed OE and alternative codes are included below for fast identification.

Function And Application

The climate pipe is a rigid/soft line in the vehicle air conditioning system that routes refrigerant between components (such as the evaporator, expansion valve, accumulator/drier or condenser depending on system layout). It ensures sealed transport of refrigerant and maintains correct pressure and temperature conditions inside the A/C circuit. A damaged or leaking pipe causes pressure loss, reduced cooling efficiency and may lead to compressor damage if contaminants enter the system.

Replacement Procedure (Overview)

Only qualified personnel with the correct tools should perform A/C repairs. Typical replacement steps:

• Recover refrigerant from the system using certified recovery equipment.
• Remove clamps and connections securing the old pipe; keep track of sealing rings (O-rings).
• Fit the new pipe into position, replacing all O-rings with new ones sized for the joints and lubricated with refrigerant-compatible lubricant.
• Reassemble fittings to the manufacturer recommended torque where available.
• Evacuate the system with a vacuum pump to remove moisture and air, then recharge with the correct type and amount of refrigerant.
• Perform leak test and functional check of the A/C system (pressure test and cooling performance verification).

Installation Recommendations

Follow industry best practices and legal requirements for handling refrigerants. Always use certified refrigerant recovery/recharge equipment. Replace associated O-rings and seals when installing a new pipe to ensure leak-free joints. After fitting, vacuum the system to remove moisture and refill with the manufacturer-specified refrigerant and lubricant. If the vehicle has experienced compressor failure, flush the system to remove debris before installing the new pipe.

Most Common Failure Causes

• Corrosion, especially in regions with road salt exposure, leads to perforation and leaks.
• Mechanical damage from impacts, stone chips or improper previous repairs.
• Deterioration of O-rings and sealing surfaces causing slow leaks over time.
• Contamination after internal compressor failure (metal particles clogging lines and connections).
• Vibration and chafing where the pipe contacts other components, eventually wearing through the material.

Technical Information

• Manufacturer: Stellantis / Citroén / Peugeot
• Model: Citroën C4, Citroën C4 Picasso, Peugeot 307, Peugeot 3008 (first generation)
• Product Codes: 9650200980, 9656859180
• Other Numbers: 6460LZ, 6460XP, 6477D4

Function And Purpose

This air conditioning pipe carries refrigerant between key A/C components (compressor, condenser, evaporator or receiver-drier, depending on the circuit layout). It ensures sealed, low-loss transfer of refrigerant and oil while withstanding pressure, temperature cycles and vibration. A correctly functioning pipe is essential for efficient cooling and to prevent moisture and air ingress.

Replacement And Installation

Overview of typical replacement steps (for experienced mechanics or qualified workshops):

• Recover refrigerant from the A/C system using certified recovery equipment (legal requirement in many regions).
• Remove retaining clamps and disconnect fittings from mating components. Note the routing and any brackets to ensure correct refit.
• Replace all O-rings/seals with new ones sized to the vehicle specification and lubricate with the correct refrigerant oil (PAG) as per manufacturer guidance.
• Fit the new pipe, secure clamps and torque fittings to manufacturer values where available.
• Evacuate system with vacuum pump, then charge with correct type and mass of refrigerant and oil as specified for the vehicle.
• Perform leak check and functional test of the A/C system (pressure, temperature and compressor operation).

Installation Recommendations

• Always use proper refrigerant recovery and charging equipment; refrigerant handling often requires certified personnel.
• Replace O-rings and seals whenever a line is opened; reuse significantly increases leak risk.
• Inspect adjacent components (condenser, receiver-drier, compressor) for damage or contamination before refit.
• Avoid kinking or sharp bends during installation; maintain original routing and secure to factory mounting points to prevent chafing.
• Use correct lubricants and follow manufacturer’s refrigerant and oil capacity specifications.

Most Common Causes Of Failure

Failures typically occur due to corrosion at metal joints, chafing against bodywork or other components, road debris impact, degraded rubber joints or O-rings, and long-term exposure to heat cycles. Small leaks often start at fittings or crimped sections, leading to gradual refrigerant loss, reduced cooling performance and potential compressor contamination if moisture enters the system.

Why Mechanics Search By Part Number

Technicians and DIYers frequently locate this pipe using OEM or supplier numbers (e.g., 6460LZ, 6460XP, 9650200980) to ensure direct fit and compatibility. Including these references in your search or order increases the chance of a quick and correct match.

Technical Information

• Manufacturer: Stellantis (Citroën/Peugeot)
• Model: Citroën C4, Citroën C4 Picasso, Peugeot 307, Peugeot 3008 (first generation) – 1.6 HDi engines
• Product Codes: 9650200980, 9656859180
• Additional Numbers: 6460LZ, 6460XP, 6477D4

Function And Symptoms

The pipe is part of the vehicle’s air conditioning refrigerant circuit and carries high- or low-pressure refrigerant between components (compressor, condenser, evaporator, dryer/accumulator). When the pipe leaks or becomes blocked, symptoms include loss of cooling, hissing from under the bonnet, oil traces around connections, or visible damage to the pipe. Leaks reduce system performance and can lead to compressor damage if left unaddressed.

Replacement Procedure

Replacement should be performed by a qualified technician or an experienced DIY mechanic with the correct tools. Typical steps:

• Safely recover and store refrigerant with an approved recovery machine (legal requirement in many jurisdictions).
• Depressurize the system and remove components obstructing access to the pipe (if required).
• Disconnect fittings and remove the damaged pipe. Inspect mating surfaces and connectors for corrosion or damage.
• Replace sealing O-rings with new O-rings of the correct size and material, lubricated with the manufacturer-specified refrigerant oil.
• Install the replacement pipe, torque fittings to manufacturer recommendations, and secure clamps.
• Evacuate the system with a vacuum pump to remove air and moisture, perform a leak test, then charge the system with the correct refrigerant and oil volume according to vehicle specifications.
• Verify operation, check for leaks, and confirm proper cooling performance.

Installation Recommendation

Always use correct sealing parts (O-rings) and the manufacturer-specified refrigerant oil when assembling A/C connections. After installation perform a vacuum and leak test before charging the system. Use personal protective equipment and follow environmental and safety regulations for refrigerant handling. If you are not equipped with recovery/vacuum/charging tools, have the final evacuation, leak test and charging performed by an AC-certified workshop.

Why The Part Most Often Fails

Common failure causes include age-related degradation of O-rings and seals, corrosion of metal lines (especially in regions with road salt), mechanical damage from impacts or chafing, and stress at connection points from vibration. Contamination or incorrect oil/refrigerant use in the system can accelerate wear and cause premature leaks.

Compatibility And Search Tips

Customers often search using product numbers such as 9650200980, 9656859180 or manufacturer cross-references 6460LZ / 6460XP / 6477D4. Verify fitment against vehicle model and engine code listed in the Technical Information section to ensure compatibility.
