Description
Air connection at the intercooler for Citroën Peugeot 2.0 HDi RH02.
Product Overview
This air connection hose fits the intercooler circuit on 2.0 HDi RH02 engines used in a range of Citroën and Peugeot vehicles. Designed for mechanics and experienced DIYers, the part restores a reliable path for compressed air between the turbo/intercooler and the intake tract, helping to maintain correct boost delivery, drivability and fuel economy.
Key Benefits
- Direct replacement for the original intercooler connection on compatible 2.0 HDi RH02 applications.
- Helps Eliminate Boost Leaks That Cause Loss Of Power, Poor Acceleration And Limp Mode.
- Durable construction Resistant To Engine Bay Heat, Oil Vapours And Vibration.
- Quick Fit For Workshop Repairs — Common Replacement Part During Turbo/Intercooler Service.
Compatibility And Fitment
Fits Common Models With 2.0 HDi RH02 Engines: Citroën C4 Picasso, Citroën C5 X7, Peugeot 3008 I, Peugeot 5008 I. Always match the shape and connection diameter with the part removed to ensure correct fitment.
Function And Failure Modes
This hose connects the intercooler outlet or inlet to the intake tract, carrying pressurised air from the turbocharger through the intercooler into the engine. Typical causes of failure include material degradation from heat and oil contamination, repeated pressure cycles causing cracks or splits, damage from improper clamping, and impact or abrasion from adjacent components. A failing connection usually manifests as boost loss, hissing sounds under load, rough running or turbo-related fault codes.
Installation Recommendations
- Perform Work When The Engine Is Cold. Allow Turbo And Intercooler To Cool Before Starting.
- Relieve Any Residual Boost Pressure By Letting The Engine Stand With The Ignition Off.
- Remove Old Clamps And Hose Carefully; Inspect Intercooler And Turbo Pipe Ends For Damage Or Corrosion.
- Fit The New Connection Ensuring Proper Orientation And Full Seating On Both Ends.
- Use Appropriate Clamps For Boost Applications (Worm-Gear Or T-Bolt Clamps Recommended) And Tighten Evenly To Avoid Pinching The Hose.
- After Installation, Start The Engine, Check For Leaks Under Load And Re-Torque Clamps If Necessary.
- Inspect Adjacent Hoses, Intercooler Seals And Turbo Connections While Replacing This Part.
Why This Part Commonly Fails
Heat Cycling And Oil Contamination Over Time Soften And Weaken The Hose Material, Leading To Cracks Or Splits. Repeated Boost Pressure Spikes, Poor Or Loose Clamping And Mechanical Abrasion Also Accelerate Wear. Vehicles With High Mileage Or Frequent Short Trips Tend To Show Earlier Deterioration.

Notes For Mechanics And DIYers
When replacing air connections, always check the entire intake tract and intercooler for hidden damage. Using high-quality clamps and ensuring correct hose seating will significantly extend service life. This is a common, straightforward repair for workshops and competent home mechanics; however, if other turbo or engine management faults are present, further diagnosis of the turbocharger, intercooler and pressure sensors may be required.
