Fitment And Identification
Compatible with Citroën C4 and Peugeot 307 vehicles fitted with 1.4 16V, 1.6 16V and 2.0 16V engines. When searching or ordering, use the OEM part numbers listed above to confirm exact match with the existing pipe. The pipe connects between the compressor/condensor/drier sections depending on the vehicle layout—verify routing and connection types against the old component before installation.
Installation Recommendations
- Recover Refrigerant: Always recover the refrigerant with certified recovery equipment in accordance with local regulations before opening the system.
- Replace Seals: Fit new O-rings and sealing washers at every connection; lubricate O-rings with the correct compressor oil to ensure sealing and long life.
- Clean System: Inspect condenser, receiver/drier and orifice tube/expansion valve for debris; replace the receiver/drier if contaminated or aged.
- Vacuum And Recharge: Evacuate the system to remove moisture and check for leaks, then recharge with the correct type and quantity of refrigerant and oil as specified by the vehicle manufacturer.
- Torque And Routing: Secure clamps and brackets to factory torque where specified and ensure the pipe routing prevents chafing and contact with hot or moving parts.
- Safety: Wear appropriate PPE. Use calibrated tools and leak-detection equipment for testing.
Why The Part Fails
Air conditioning pipes typically fail due to corrosion, mechanical damage or degradation of seals. Common causes include long-term exposure to road salt and moisture (leading to pitting and perforation), vibration-induced fatigue at bends or brackets, and deteriorated O-rings at connection points. Physical impact from road debris or improper routing that causes chafing will also cause leaks. Identifying the failure mode helps prevent repeat failures—replace worn mounts and seals and correct any routing issues when fitting the new pipe.
Notes For Mechanics And DIYers
This pipe is aimed at technicians and experienced DIY enthusiasts who are comfortable working with vehicle air conditioning systems. Use OEM-quality seals and follow manufacturer procedures for leak testing and charging. Searching by part number (9650629480, 9681723480, 6460LV, 6460ZP) will speed up identification and ordering.
Additional Information
