Description
Two connected air conditioning pipes for Citroën C8 and Peugeot 807. For 2.0 HDi engines 88 kW and 100 kW.
This pair of joined A/C pipes is an OE-fit replacement ideal for Citroën C8 and Peugeot 807 models equipped with the 2.0 HDi engines. The assembly restores proper refrigerant flow between evaporator, condenser and compressor connections and is suitable where original part numbers match 1440081180 / 6460VE / 6460VG and related references. The pipes are manufactured to fit the factory routing and mounting points, helping to eliminate leaks and pressure losses that reduce cooling performance.
Fitment
Designed For: Citroën C8, Peugeot 807
Engine Compatibility: 2.0 HDi (88 kW and 100 kW)
Function And Typical Symptoms
Function: These climate (A/C) pipes carry refrigerant under pressure between the system components and provide sealed connections at flanges and O-ring joints. They ensure correct circulation of refrigerant for effective cabin cooling.
Common Symptoms Of A Faulty Pipe Assembly:
– Reduced or no cooling performance
– Visible oil stains or refrigerant residue at pipe joints
– Hissing or bubbling sounds from the A/C system (indicating leaks)
Replacement Procedure
General Steps (overview for professionals and experienced DIYers):
- Recover refrigerant from the A/C system using certified recovery equipment (legal requirement in many regions).
- Remove engine covers and any components blocking access to the pipe routing.
- Unbolt pipe brackets and disconnect fittings at the compressor, condenser or evaporator according to the vehicle layout.
- Replace old O-rings and seals with new ones of the correct size and material; lightly lubricate O-rings with appropriate PAG oil.
- Install the new pipe assembly, secure clamps and brackets to factory torque values, and check alignment to avoid rubbing.
- Perform a vacuum and leak test, then recharge the system with the correct refrigerant and oil quantities following manufacturer specifications.
Installation Recommendations
- Always recover and recycle refrigerant with certified equipment—do not vent to atmosphere.
- Replace O-rings and seals whenever the pipe assembly is changed to ensure leak-free joints.
- Use the correct lubricant (PAG) compatible with the vehicle’s refrigerant and compressor type.
- Inspect mounting brackets, clips and surrounding hoses for wear and corrosion; replace any damaged supports to prevent future leaks.
- After installation, carry out a proper vacuum, leak test and system recharge to manufacturer specifications for reliable cooling performance.
Why This Part Most Often Fails
Common Causes Of Failure:
– Corrosion From Road Salt And Moisture At Metal Joints
– Mechanical Damage From Impact Or Rubbing Against Other Components
– Age-Related O-Ring And Seal Degradation Leading To Slow Leaks
– Thermal Cycling And Vibration Causing Metal Fatigue At Connections
