Frequently searched by part numbers 88703-0H010A and 6460QV, this pipe is compatible with the 1.0i 12V engine variants of the Citroën C1, Peugeot 107 and Toyota Aygo produced between 2005–2014.

Technical Information

• Manufacturer: Stellantis (Citroën/Peugeot)
• 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.

Part numbers like 88703-0H010A and 6460QV are commonly used in searches — ordering by these codes helps ensure you receive the correct replacement for the Citroën C1, Peugeot 107 and Toyota Aygo 1.0i 12V models (2005–2014).

• Model: Citroën C1, Peugeot 107
• Product Codes: 88720-0H010C, 6460SX
• Additional Numbers: 6460SX | 88720-0H010C

Function And Fitment

This double climate pipe is part of the vehicle’s air conditioning refrigerant circuit. It carries refrigerant between system components (compressor, condenser, evaporator/receiver-drier) and must provide leak-free connections under pressure. The item fits 1.0i 12V engines produced between 2005 and 2014 for Citroën C1 and Peugeot 107.

Installation Recommendations

Replacement of A/C refrigerant lines requires correct workshop procedures and appropriate equipment. Recommended steps:

• Recover refrigerant using certified recovery equipment before opening the system; never release refrigerant to atmosphere.
• Replace sealing O-rings at all disconnected joints with new, correctly sized O-rings lubricated with the correct PAG oil.
• Visually inspect mating surfaces and fittings for damage or corrosion; clean before assembly.
• Perform vacuum evacuation and moisture check, then recharge the system to the specified refrigerant charge and oil quantity.
• Leak-check the system (electronic leak detector or UV dye) and verify operating pressures and A/C performance after service.
• If you are not equipped to recover/recharge refrigerant safely, have the work performed by an authorized A/C service provider.

Most Common Causes Of Failure

Refrigerant lines commonly fail due to age-related corrosion, vibration-induced fatigue at joints or bends, abrasive wear from contact with other components, or damage during previous repairs or component replacements. Leaking O-rings and degraded sealing surfaces also lead to loss of refrigerant and reduced cooling performance.

Why Buy This Part

If your Citroën C1 or Peugeot 107 is losing cooling efficiency or shows visible oil traces near A/C connections, replacing the double climate pipe with a correct-fit unit and new seals is a cost-effective repair. The supplied product codes 88720-0H010C and 6460SX make it easy to find the exact part needed for these models.
