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

• Part Number For Search: 1606380480 — commonly used by technicians to locate the correct replacement.

Function And Symptoms Of Failure

The air conditioning pipe transfers refrigerant between A/C components (compressor, condenser, evaporator, dryer/receiver). When the pipe develops leaks or blockages, common symptoms include reduced cooling, hissing sounds from the system, visible oil traces around fittings, and pressure imbalance during service checks. Leaks typically occur at connection points, crimp joints, or where corrosion has weakened the pipe.

Why This Part Fails Most Often

• Corrosion From Road Salt And Moisture: External corrosion can lead to pinhole leaks, especially in regions with winter salting.
• Mechanical Damage: Impact from debris or improper previous repairs can deform lines and cause leaks.
• O‑Ring Ageing: Seals at connections harden and lose sealing capability, producing leaks at joints.
• System Contamination: Debris or moisture inside the refrigerant circuit can accelerate internal damage and clogging.

Installation Recommendations

Recommended For Experienced Technicians Or Skilled DIYers With Proper Equipment. Typical replacement steps:

• Recover Refrigerant: Legally recover refrigerant with certified recovery equipment before opening the A/C system.
• Inspect And Replace Seals: Replace all O‑rings and seals at connection points; lubricate new O‑rings with correct PAG oil to ensure proper sealing.
• Check Associated Components: Inspect receiver/drier (or accumulator), hoses, and compressor for contamination or wear; replace the receiver/drier if contaminated or open to atmosphere.
• Vacuum And Recharge: Evacuate the system to remove moisture and air, then recharge with the correct refrigerant type and specified charge mass for the vehicle.
• Leak Test And Functional Check: Perform a pressure/leak test and verify cooling performance and correct system pressures under load.

Follow Manufacturer Procedures And Safety Rules During Work. If unsure about refrigerant handling, evacuation or charging, use a professional A/C service.
