Technical Information

• Manufacturer: Stellantis (Citroën/Peugeot)
• Model: Citroën C4 Picasso
• Product Codes: 9681781280, 6477H9
• Additional Numbers: 6477H9 | 9681781280

Function And Application

This refrigerant pipe is a part of the vehicle’s air conditioning circuit. Its role is to transport refrigerant between components (compressor, condenser, evaporator and receiver/drier) under the required operating pressures and temperatures. Proper sealing and corrosion resistance are essential to prevent leaks and maintain system efficiency.

Typical Failure Modes And Service Life

Failures usually occur through gradual deterioration: corrosion, mechanical damage from road debris or impact, chafing against adjacent parts, or degraded O-rings and seals at the connections. Vehicles exposed to salty roads or harsh environments are more prone to leaks. There is no fixed replacement interval; pipes commonly fail on higher-mileage or older cars (for example after several years of service), but should be inspected whenever the AC system loses cooling performance or when other components are replaced.

Installation Recommendations

Recommended procedure for replacement (intended for qualified technicians or experienced DIYers with proper equipment):

• Recover Refrigerant Safely: Recover the refrigerant using an R134a/R1234yf recovery/recycle machine in compliance with local regulations.
• Access And Remove: Remove any obstructing components to gain access to the pipe. Carefully disconnect fittings; mark routing to ensure correct refit.
• Replace Seals: Always replace O-rings/seals at each connection with correctly sized, lubricant-coated new O-rings compatible with the system oil and refrigerant.
• Install New Pipe: Fit the new pipe and tighten connections to manufacturer recommended procedures. Avoid kinking or undue stress on the line.
• Evacuate And Charge: Evacuate the system to remove moisture and air, then charge with the correct refrigerant type and specified oil quantity. Perform leak and pressure checks.
• Final Checks: Start the engine and confirm proper system pressures and cooling performance. Re-inspect fittings after a short test drive.

Important: Refrigerant handling requires certified equipment and adherence to safety and environmental rules. If you are not equipped to recover and recharge the AC system, entrust this step to a qualified workshop.

Why The Part Is Often Replaced

Most replacements are due to refrigerant leaks that cause loss of cooling, often detected as reduced AC performance or visible oil traces around pipe joints. Corrosion at the pipe or fittings, damage from road debris, or hardening of connection O-rings are the most common root causes. Replacing the pipe and seals together addresses the leak source and prevents repeat failures.

4. Replace Seals: Always replace O-rings/seals at each connection with new, correct-size refrigerant-rated O-rings lubricated with the correct PAG oil type.
5. Install Pipe: Fit new pipe and torque fittings to manufacturer specification to avoid leaks or deformation.
6. Vacuum And Recharge: Evacuate system to required vacuum level, perform leak check, then recharge with the correct refrigerant type and oil quantity per vehicle specification.
7. Functional Test: Run the A/C system, check pressures and verify cooling performance and leak-free operation.

Always follow manufacturer safety procedures. Wear protective gloves and eye protection when working with refrigerant and pressurized systems.

Why This Part Most Often Fails

Air conditioning pipes commonly fail due to a combination of factors: corrosion from road salts or moisture on metal sections, mechanical damage from impacts or debris, and seal/O-ring deterioration at connection points. Vibration and thermal cycling over years can lead to fatigue at bends or joints. In vehicles exposed to harsh climates or where the pipe routing is close to moving components, the risk of chafing or puncture increases. When a leak develops, the system loses refrigerant and oil, which can quickly lead to compressor overheating and reduced cooling performance.

• Model: Citroën C1, Peugeot 107, Toyota Aygo
• Product Codes: 88703-0H010A, 6460QV
• Other Numbers: OEM/Reference numbers as listed above

Function And Compatibility

The climate (A/C) pipe routes refrigerant between components of the air conditioning system (for example between the evaporator, compressor and condenser depending on the exact routing). It ensures a sealed passage for refrigerant and oil under operating pressure and temperature. This pipe is manufactured to match the original shape and fitting positions used on the PSA/Toyota joint platform, guaranteeing correct fitment on the specified 1.0i 12V models.

Common Failure Causes

AC pipes most often fail due to corrosion (especially in regions with road salt), mechanical damage from road debris or improper previous repairs, degraded seals and O-rings at connection points, and stress from vibrations or movement over time. Rubber or plastic joints can harden and crack, while metal lines can develop hairline fractures causing slow refrigerant leaks.

Symptoms Indicating Replacement

• Reduced cooling efficiency or intermittent cooling.
• Visible oil residue or wet spots around pipe fittings.
• Audible hissing from the A/C system or sudden loss of refrigerant pressure.
• Illuminated A/C faults or compressor cycling due to low refrigerant.

How To Replace

Replacement requires depressurizing and evacuating the refrigerant from the system with certified equipment. Steps typically include:

• Recover refrigerant using approved recovery machine (must be performed by a certified technician).
• Remove any covers or brackets obstructing access to the pipe and mark routing if necessary.
• Disconnect fittings and remove the damaged pipe; replace all O-rings/seals with new, correctly sized parts lubricated with the appropriate refrigerant oil (PAG type as specified for the vehicle).
• Install the new pipe, secure clamps/brackets and ensure correct routing to avoid chafing.
• Perform vacuum evacuation, leak test and recharge the system to manufacturer refrigerant specification.

Installation Recommendations

Always use correct seals and the specified refrigerant oil when assembling A/C connections. Pressure-test the system after installation and check all mounting points to prevent future chafing or vibration stress. Because handling refrigerant is regulated and requires special tools, recovery and recharging should be done with certified equipment. Inspect surrounding components (compressor, condenser, dryer/receiver) for damage and replace any compromised seals or clamps during the job.

Why The Part Most Commonly Fails

The most common causes are corrosion from environmental exposure, mechanical damage from impacts or improper previous repairs, and seal degradation at connection points. Small leaks often develop slowly and go unnoticed until cooling performance decreases significantly.
