Engine Cover 1.8 16V 6FY For Citroën C4 Picasso, C5 And Peugeot 407
This engine cover designed for the 1.8 16V 6FY petrol engines fits Citroën C4 Picasso, Citroën C5 and Peugeot 407. Cross-referenced with part numbers 9653373180, 9653425980 and code 0248N4, the cover protects the top of the engine from dirt, oil spray and heat, helps retain correct routing of hoses and wiring, and ensures proper clearance for service access. The part is ideal for professional mechanics and competent DIY enthusiasts who often search by product code.
Function And Benefits
The engine cover provides protective shielding for ignition coils, fuel lines and electrical connectors while contributing to noise reduction and orderly engine bay appearance. It prevents debris ingress, reduces the risk of accidental contact with hot or moving components during routine checks, and helps guide small airflows around the engine top. Replacing a damaged cover restores protection and can prevent secondary damage to exposed components.
Installation Guide
Replacement is straightforward for a trained mechanic or DIYer with basic tools. Typical steps:
- Allow The Engine To Cool Completely Before Starting Work.
- Remove Any Cosmetic Fasteners Or Clips Holding The Cover In Place (Retaining Screws, Plastic Clips Or Bolts).
- Carefully Lift Off The Old Cover, Noting The Position Of Any Grommets, Insulators Or Brackets.
- Inspect Mounting Points And Rubber Supports; Clean The Seating Area From Oil And Dirt.
- Fit The New Cover, Ensuring Correct Alignment Of Tabs And Grommets, Then Secure Fasteners To Manufacturer Recommendations.
Typical replacement time: 15–30 minutes depending on accessibility and number of fasteners. Use common hand tools such as a ratchet, appropriate sockets and screwdrivers. Observe general safety precautions and avoid forcing broken tabs.
Replacement Interval And Symptoms
The cover has no fixed service interval but should be inspected during routine maintenance. Common signs that indicate replacement is needed include visible cracks, broken mounting tabs, oil saturation that has degraded the material, rattling noises from loose fasteners, or deformation from heat. When damaged, the cover can expose ignition components and connectors to contaminants and increase the likelihood of secondary faults.
