Description
Turbo hose 1.6 HDi for Citroën C5 II, C5 III and Peugeot 407.
High-quality turbo hose designed for 1.6 HDi engines used in Citroën C5 (II and III generations) and Peugeot 407. Ideal for professional workshops and experienced DIY mechanics who need a direct-fit replacement that restores turbocharger boost integrity. The hose is supplied to match the OEM fitment and is often searched for by the part code 0382EH, making it easy to find and order. Replacing a cracked or leaking turbo hose will quickly recover lost power, reduce turbo lag and prevent unmetered air from affecting engine management.
Technical Information
- Manufacturer: Stellantis
- Model: Citroën C5 II, Citroën C5 III, Peugeot 407
- Product Codes: 0382EH
- Additional Numbers: Not Available
Function And Benefits
The turbo hose connects the turbocharger to the intercooler or intake tract and carries pressurised boost air. It must withstand high temperatures, pressure spikes and occasional oil contamination. A properly functioning hose ensures stable boost pressure, accurate air-metering and smooth engine response under load. Replacing a degraded hose restores fuel economy, reduces engine knock risk and protects the turbo and mass airflow/pressure sensors from ingesting oil or debris.
Common Failure Reasons
- Ageing And Heat Exposure: Rubber or silicone hardens and cracks after long-term exposure to engine bay temperatures.
- Oil Contamination: Turbocharger oil leaks or blow-by can weaken the material and accelerate deterioration.
- Loose Or Damaged Clamps: Insufficient clamp force or corroded clamps lead to boost leaks at hose joints.
- Mechanical Damage And Vibration: Contact with other components or repeated vibration can wear or split the hose.
Expected Service Life
Service life depends on driving style and conditions. Typical replacement intervals are commonly in the range of 80,000–150,000 km, but inspection at regular service intervals is recommended. Vehicles with frequent short trips, high mileage, or prior turbo oil leaks may require earlier replacement.
Installation Recommendations
- Allow The Engine To Cool Completely Before Starting Work.
- Relieve Any Residual Boost Pressure By Cranking The Engine With The Fuel System Disabled Or Following Manufacturer Procedures.
- Loosen Hose Clamps And Carefully Remove The Old Hose; Inspect Mating Surfaces For Damage Or Carbon Build-Up.
- Clean The Connection Points (Turbo Outlet/Intercooler/Intake) And Replace Corroded Or Worn Clamps With Quality Stainless-Steel Clamps.
- Fit The New Hose Ensuring Correct Orientation And Full Seat On Spigots; Secure Clamps Firmly But Avoid Over-Tightening To Prevent Hose Distortion.
- After Installation, Start The Engine And Check For Boost Leaks Under Load; Reinspect Clamps After A Short Test Drive.
Recommendation For Mechanics And DIYers
Always inspect related components when replacing the turbo hose: clamps, intercooler pipes, vacuum lines and the turbocharger oil seals. Replace clamps if corroded and check for signs of oil leakage from the turbo. For reliable results use the correct part code (0382EH) and follow safety precautions—wear eye protection and gloves. If uncertain about hidden damage to adjoining components, perform a boost-pressure or smoke test to confirm system integrity.
Why Choose This Part
Clear compatibility with Citroën C5 II/III and Peugeot 407, OEM-related product code 0382EH and fitment for the 1.6 HDi turbo system make this hose a practical choice for rapid repair. It restores proper turbo operation and prevents drivability faults caused by boost leaks, helping workshops and DIY mechanics complete reliable repairs quickly.
