Description
Lower timing cover for Citroën Peugeot 1.4 HDi and 1.4 16V HDi
This lower timing cover is a direct-fit protective component for Citroën and Peugeot 1.4 HDi engines. It shields the timing belt/chain area and associated pulleys from road debris, dirt and moisture, helping to prolong the life of the timing system and maintain correct clearances. Designed for workshop and DIY use, the cover is frequently searched by its product codes, so compatibility and part numbers are included below to help technicians find the right replacement quickly.

Function And Benefits
The lower timing cover prevents contamination of the timing belt and tensioning components by stones, salt and road spray. It also helps retain light oil spray and keeps routing clearances consistent. Replacing a damaged cover reduces the risk of foreign objects compromising the belt or pulleys, and provides a secure mounting surface for clips and fasteners used during timing system service.
Installation Recommendations
- Work Safely: Park on a level surface, use appropriate supports and follow manufacturer safety procedures before working under the vehicle.
- Access: Remove engine undertray / splash shield and any obstructing ancillary belts or brackets to reach the lower timing cover.
- Removal: Unscrew or unclip all fasteners securing the old cover. Note the position of retaining clips and any sealing elements for correct reassembly.
- Inspection: Check timing belt, tensioner, idlers and seals while the cover is removed. Replace any worn components at the same time—this is efficient and prevents repeated labour.
- Fitment: Clean mating surfaces, fit the new cover ensuring correct orientation, and secure with original-type fasteners. Rotate the engine by hand to verify there is no interference between cover and pulleys.
- Final Check: Refit splash shield and ancillary parts, then start the engine and listen for unusual noises. Verify no contact or rubbing occurs at idle and during a short road test.
Common Failure Reasons
- Mechanical Damage: Impact from road debris or striking obstacles can crack or deform the plastic cover.
- Ageing And Heat: Long-term exposure to heat and oil can make the cover brittle, causing cracks or broken mounting tabs.
- Broken Fasteners: Clips or screws can shear off, allowing the cover to work loose and rub against moving parts.
- Service Damage: The cover is often removed during timing-belt replacement; improper handling or reinstallation can damage it.
- Contamination And Oil Ingress: Excessive oil leaks or heavy contamination can accelerate material degradation and hide damage until failure occurs.
Note: There is no fixed service interval for the lower timing cover; it is commonly replaced during timing-belt service or whenever physical damage or deterioration is detected. When replacing the cover, it is a good practice to inspect the entire timing system to ensure long-term reliability.
