Description
Engine Cover 2.0 HDI RH02 for Citroën and Peugeot vehicles
Product Overview
This genuine-style engine cover is designed for 2.0 HDI diesel engines used in a range of Citroën and Peugeot models. The cover protects top-end components from dirt and debris, improves engine bay appearance and contributes to acoustic insulation by reducing engine noise. It is a commonly searched item by OEM numbers, so customers and technicians often find it using part references such as 9673129380, 9674161080 or 0137H4.
Who This Is For
Ideal for professional mechanics and DIY enthusiasts performing engine-bay repairs or restorations. Use this cover when replacing a damaged or missing trim cover, after maintenance that requires access to the cylinder head area, or when renewing worn mounting clips and pads for a clean, factory look.
Fitment And Function
The cover fits 2.0 HDI RH02 engine variants in several Citroën and Peugeot models. Functionally it:
- Shields wiring, injectors and engine tops from dust and road grime.
- Provides a modest level of sound deadening to reduce perceived engine noise.
- Helps manage small airflow patterns in the engine bay and conceals serviceable components for a tidy appearance.
Typical Material And Construction
These engine covers are typically made from moulded thermoplastic with an attached sound-insulating pad and use rubber grommets or plastic clips for mounting. The design balances lightweight construction with sufficient heat and vibration resistance for under-hood use.

Installation Recommendations
- Allow the engine to cool before starting work to avoid burns and to protect plastic parts.
- Remove the existing cover by taking out retention clips or screws. Use trim tools to avoid damaging surrounding trim and a suitable socket or Torx set if required.
- Inspect and renew mounting grommets and clips if they are cracked, stretched or missing — replacement clips are inexpensive and prevent vibration and rattles.
- Clean mating surfaces of oil and debris before fitting the new cover so it sits flush and secures correctly.
- Press the cover into place until all rubber grommets engage and any screws or fasteners are reinstalled. Avoid excessive force that could crack the plastic.
- No special coding or electrical reprogramming is required for a standard engine cover; installation is mechanical only.
Why This Part Fails Most Often
- Broken Or Missing Clips: Repeated removal, impact or simple aging causes clips and grommets to fail, letting the cover vibrate or fall off.
- Heat And Embrittlement: Long-term exposure to under-bonnet heat makes plastic brittle, eventually leading to cracks.
- Oil And Fluid Contamination: Persistent oil leaks or fluid spills degrade mounting pads and insulation, making the cover loose or stained.
- Impact Damage: Debris, accidental contact during service or collisions can crack or deform the cover.
Maintenance And Replacement Advice
There is no fixed service interval for engine covers; replace when cracked, warped, heavily contaminated or when rubber mounts are no longer effective. During routine servicing, inspect the cover and fasteners and fit new clips if necessary to avoid noise and further wear.
Search And Identification Tips
Technicians often search using OEM part numbers—enter 9673129380, 9674161080 or 0137H4 when looking up the correct cover for 2.0 HDI RH02 engines. Also reference the vehicle model and engine code to confirm compatibility before installation.
