Description
Air conditioning pipe for Citroën C1, Toyota Aygo and Peugeot 107 for 1.0i 12V engines from 2005 to 2014.
Description
Replacement air conditioning pipe designed to match original equipment fitment for small city cars from the Stellantis family and their Toyota sibling. This A/C line carries refrigerant between components of the air conditioning circuit and is supplied under OE references commonly used by mechanics and DIY enthusiasts. Ideal when the original pipe is leaking, mechanically damaged or corroded.
Technical information
- Manufacturer: Stellantis (OE for Citroën / Peugeot / Toyota)
- Model: Citroën C1, Peugeot 107, Toyota Aygo
- Product codes: 88703-0H010A, 6460QV
- Additional numbers: Engine: 1.0i 12V; Model years: 2005–2014
Function
The air conditioning pipe routes refrigerant between the evaporator, compressor, condenser and receiver/drier as part of the vehicle’s cooling circuit. It ensures a sealed path for high- and low-pressure refrigerant flow and keeps the system functioning at designed pressures and temperatures.
Common failure causes
Most frequent causes of failure are: corrosion of metal lines or fittings, mechanical damage from road debris or improper previous repairs, degraded seals and O-rings at connection points, and chafing where the pipe contacts other components. Leaks typically occur at joints or at areas weakened by corrosion or impact.
Replacement procedure (overview)
- Have the refrigerant recovered by a certified technician before disconnecting any A/C components.
- Carefully release pressure and remove retaining clips or fasteners holding the pipe in place.
- Replace all associated O-rings and seals with the correct size and material; lubricate new O-rings with the appropriate PAG oil.
- Install the new pipe ensuring correct routing and secure mounting to avoid future chafing or vibration contact.
- Perform a vacuum and leak test, then recharge the system with the specified refrigerant and oil charge for the vehicle.
- Confirm system operation and check for leaks after a short test drive.
Installation recommendations
- Always have refrigerant recovered and recharged by a qualified technician with appropriate A/C service equipment.
- Replace O-rings and inspect the receiver/drier (or accumulator); when one part of the A/C circuit fails, moisture and contaminants may have entered the system.
- Use correct torque values for fittings and ensure proper routing to avoid contact with moving parts or hot surfaces.
- After installation, perform a vacuum hold test and pressure/leak test before charging the system.
Why this part is commonly replaced
Urban use, long service life and exposure to road salt and debris accelerate corrosion and mechanical wear on A/C piping. Small impacts, vibrations and aged seals lead to refrigerant leaks, which reduce cooling performance and ultimately require pipe replacement to restore reliable air conditioning.
Notes for mechanics and DIYers
Searches for this part are frequently made by OE number (88703-0H010A / 6460QV), so including those codes in your order helps locate the correct item quickly. Ensure you match the engine and year range (1.0i 12V, 2005–2014) when selecting the part.
