Description
Air connection at the intercooler for Citroën and Peugeot 2.0 HDi vehicles. It is from a Citroën C5 RHR.
This intercooler air hose (part number 0382FJ) is a direct-fit replacement for 2.0 HDi turbocharged engines used on selected Citroën and Peugeot models. Designed for mechanics and DIY enthusiasts, the hose restores proper charge-air routing between the turbo/intercooler assemblies and the intake circuit, eliminating boost leaks that cause loss of power, rough running and higher fuel consumption. The part is commonly searched by the OEM product code 0382FJ—entering the code speeds up finding the correct item for your vehicle.
Technical Information
- Manufacturer: Stellantis (Citroën / Peugeot)
- Model: Citroën C5, Peugeot 407 (2.0 HDi — RHR engine application)
- Product Codes: 0382FJ
- Other Numbers: RHR (Engine Code)
Function And Application
The hose provides a sealed path for pressurised intake air around the intercooler assembly. Proper function is critical for maintaining turbo boost pressure, engine response and emissions performance. It fits the 2.0 HDi (RHR) turbocharged engines used on the listed Citroën and Peugeot models and is an original-equipment fitment in applications where 0382FJ is specified.
Installation Recommendations
- Work On A Cold Engine: Allow the engine to cool before starting to avoid burns and ensure clamps are safe to loosen.
- Inspect Surrounding Components: Check intercooler, turbo connections and nearby pipes for oil traces or damage—replace clamps if corroded.
- Remove Old Hose Carefully: Loosen clamps and remove the old hose, noting orientation and any retaining brackets.
- Fit New Hose Correctly: Ensure the hose seats fully on mating spigots and use quality clamps. Tighten clamps evenly to prevent distortion—follow manufacturer torque recommendations where available.
- Leak Check: After installation, run the engine and check for boost leaks at idle and under light load; perform a test drive to verify normal boost delivery and engine response.
- Use New Clamps If Possible: Replacing old clamps reduces the risk of future leaks, especially on older vehicles.
Most Common Failure Reasons
- Aging And Material Fatigue: Rubber hoses harden, crack or lose elasticity over time, especially under repeated heat cycles.
- Oil Contamination: Turbocharger oil leaks can soften or swell hose material and accelerate deterioration.
- Heat And Vibration: Constant exposure to engine bay heat and vibration causes micro-cracks and eventual failure.
- Poor Clamping Or Corroded Hardware: Loose or corroded clamps allow blow-by and accelerate wear at hose ends.
Why Choose This Part
Chosen by workshops for direct-fit compatibility with 2.0 HDi RHR engines, this hose restores reliable boost sealing and drivability. Searching by the OEM code 0382FJ helps you match the correct item quickly when servicing Citroën C5 or Peugeot 407 models. Installing a proper, OEM-specified hose reduces the risk of recurring boost leaks and related turbocharger stress.
If you are replacing charge-air hoses, inspect the entire intake tract and turbo for signs of oil or mechanical damage—addressing underlying causes prevents repeated failures and ensures a long service life for the new hose.
