Description
Clamp for pressurized air connection 1.6 HDi for Citroën and Peugeot vehicles.
This high-quality clamp secures the pressurized air/boost connection on 1.6 HDi engines used in Citroën and Peugeot models. Designed for mechanics and DIY enthusiasts, the part ensures a reliable seal between turbo, intercooler and intake hoses to prevent boost leaks that reduce performance, increase fuel consumption and can cause fault codes. Frequently searched under product codes 9649367980 and 0382EA, this clamp is a straightforward, cost-effective replacement during routine intake system service or when repairing a damaged hose.
Technical information
- Manufacturer: Stellantis / Citroën / Peugeot
- Model: Citroën C5, Citroën C5 X7, Peugeot 407 (1.6 HDi applications)
- Product Codes: 9649367980, 0382EA
- Other Numbers: NFP
Function and Application
The clamp holds the pressurized air hose or fitting in place on turbocharged 1.6 HDi engines, maintaining airtight connection between turbocharger, intercooler and intake manifold. A secure clamp prevents boost loss, rough running, reduced torque and potential turbo over-speed or compressor surge situations caused by sudden leakage.
Installation recommendations
- Work on a cool engine. Relieve pressure in the intake system before loosening any fittings.
- Remove the old clamp and clean mating surfaces of oil, dirt and old sealant to ensure a proper seal.
- Position the clamp squarely over the hose and fitting. Tighten progressively and evenly; avoid over-tightening to prevent hose deformation or damage to plastic fittings.
- Use a torque-limited driver if available, or tighten until secure but not crushing—the clamp should prevent movement and air leaks without cutting into the hose.
- After installation, start the engine and check for boost leaks at idle and under load (test drive). Re-check clamp tightness after the first heat cycle.
Why this part fails most often
- Corrosion and material fatigue from long-term exposure to heat, road salts and engine bay chemicals.
- Hose deterioration: cracked or softened hoses allow the clamp to slip or fail to hold pressure.
- Oil contamination and soot build-up reduce friction and sealing capability at the joint.
- Incorrect installation or excessive tightening that damages hose or fitting.
- Vibration and pressure cycling in turbocharged systems gradually loosen or fatigue clamps over time.
