Description
Engine Cover 1.6 16V HDi for 55, 66, 80 kW Engines of Citroën and Peugeot
This engine cover is designed for 1.6 16V HDi diesel engines (55, 66 and 80 kW) used across a wide range of Citroën and Peugeot models. Manufactured to match the original fit and mounting points, it protects top engine components from dirt, reduces perceived engine noise and helps manage under-hood airflow. Ideal for professional garages and DIY enthusiasts who search by part number (e.g. 9659999880, 9684889380, 9684889480, 0137E5), this cover restores the vehicle’s factory appearance while maintaining practical protection.
Key Benefits
- Direct fit for factory mounting points — simplifies replacement and ensures correct clearance for hoses and sensors.
- Protects intake components, wiring and fuel lines from debris and moisture.
- Contributes to engine bay acoustics by dampening high-frequency noise from the valve cover area.
- OEM-style design retains correct airflow and heat dispersion around the engine top.
- Part-number searchable for fast identification in workshop catalogs: 9659999880 / 9684889380 / 9684889480 / 0137E5.

Fitment And Replacement
Replacing the engine cover is straightforward for a trained mechanic or competent DIYer. Typical steps:
- Allow the engine to cool. Remove any cosmetic clips or plastic fasteners securing the cover (common are push clips and a few bolts).
- Disconnect any attached components or sensor retainers that clip to the cover — take care not to pull on wires.
- Lift the cover clear of the engine, noting the orientation and position of mounting points for correct reinstallation.
- Clean the mounting area of dirt and oil before fitting the new cover. Replace any damaged clips or fasteners to ensure a secure fit.
- Refit in reverse order, ensuring all fasteners are snug and that hoses or wiring are not pinched.
Installation Recommendations
- Use new clips or bolts if original fasteners are brittle or damaged — plastic clips often fail with age.
- Inspect adjacent components (hoses, wiring harnesses, breather lines) while the cover is removed and replace or secure any worn parts.
- Ensure correct seating around oil filler cap and breather connections to avoid rattles or leaks.
- Work on a cooled engine and keep a clean workspace to prevent debris falling into the intake area.
Why This Part Fails Most Often
Engine covers are plastic components exposed to heat cycles, oil vapors and vibration. The most common failure modes are:
- Brittle or broken plastic clips and mounting tabs due to age and heat exposure.
- Cracks or deformation from impact or from overtightening nearby components.
- Surface damage and oil contamination that reduce aesthetic appearance and can hide other maintenance issues.
Replacing the cover and worn fasteners restores proper fitment and prevents further damage to hoses or wiring routed beneath the cover.
