Function

The pipe carries refrigerant and lubricant within the air conditioning circuit, connecting key components and maintaining the correct flow and pressure balance. Proper sealing and intact fittings are essential to prevent refrigerant loss and to keep the system operating efficiently.

Compatibility And Fitment

Designed for direct replacement on Peugeot 4007 and Citroën C‑Crosser vehicles equipped with the 2.2 HDi engine where the OEM part number 1606380480 is specified. Always verify the part number against the vehicle’s service documentation or parts catalog before installation.

Installation Recommendations

• Recover Refrigerant Safely: Evacuate and recover refrigerant with certified A/C service equipment before disassembly.
• Replace Seals: Always fit new O‑rings/seals and lubricate them with the correct PAG oil specified by the vehicle manufacturer.
• Dryer/Accumulator: When opening the A/C circuit, consider replacing the receiver/drier or accumulator per manufacturer recommendations to avoid contamination and moisture-related failures.
• Leak And Vacuum Test: After fitting, perform a vacuum test to check for leaks, then recharge and verify system pressures and performance.
• Follow Manufacturer Procedure: Use correct torque values and routing; follow safety and handling procedures for pressurized refrigerant systems.

How The Part Is Replaced (Overview)

Typical replacement steps: recover refrigerant with an approved recovery unit; remove clamps and fittings securing the old pipe; replace O‑rings and check mating surfaces for damage; install the new pipe ensuring correct routing and fastening; perform a vacuum leak test, refill with the specified refrigerant and oil, and verify A/C system operation. This job is recommended for technicians or competent DIYers with appropriate tools and A/C service equipment.

Common Failure Causes

Air conditioning pipes most often fail due to corrosion from road salt and moisture, mechanical damage from impacts or chafing against nearby components, degraded O‑rings at connection points, and long‑term vibration stress. Contamination or a blocked dryer can increase internal pressure and accelerate leak formation.

Why This Part Matters

A correctly fitted A/C pipe restores proper refrigerant flow and prevents leaks that reduce cooling efficiency. Using the correct part number (1606380480) ensures correct shape, connections and reliable fitment for the specified Peugeot and Citroën models.

Notes For Mechanics And DIYers
