Description
Upper Timing Cover Citroën Peugeot 1.4 16V HDi
This Upper Timing Cover is a direct-fit replacement designed for the 1.4 16V HDi engines used in Citroën and Peugeot models. It protects the timing system from dirt, road debris and oil contamination while helping to maintain correct alignment and sealing of the timing belt/chain area. The cover is commonly referenced by OE numbers 9641898280, 9640454780 and internal code 0320T6, making it easy to find by part number when ordering or searching online.
Technical Information
- Manufacturer: Stellantis (Citroën, Peugeot)
- Model: Citroën C3; Peugeot 1007
- Product Codes: 9641898280, 9640454780
- Additional Numbers: 0320T6
Function And Benefits
The upper timing cover shields the timing components from external contamination and mechanical damage. By keeping the timing belt/chain environment clean and dry it contributes to longer component life and stable engine timing. A correctly fitted cover also prevents oil and coolant from reaching timing components, which could otherwise accelerate wear or cause belt slippage.
Typical Applications
Fits 1.4 16V HDi engines in Citroën and Peugeot small models, for example Citroën C3 and Peugeot 1007. The cover is often looked up by OE numbers 9641898280, 9640454780 or internal code 0320T6 — include these codes when searching for exact fitment.
How To Replace
- Park vehicle on level surface, disconnect battery negative terminal for safety.
- Remove any plastic engine covers and undertrays that obstruct access to the timing cover.
- Loosen accessory drive components only if they prevent access; support the engine if required by the vehicle’s service procedure.
- Carefully unbolt the upper timing cover fasteners and remove the cover. Keep track of clips and screws as some are single-use or prone to damage.
- Inspect sealing surfaces and any gasket or O‑rings; clean mating surfaces before fitting the new cover.
- Reinstall the new cover using the correct torque values for the fasteners and replace any worn clips or seals. Reassemble removed components in reverse order.
- After installation, rotate the engine by hand through at least two full revolutions and recheck fastener tightness and clearance.
Installation Recommendation
Use correct torque settings for cover fasteners and replace any damaged or brittle clips. Replace the cover together with any associated seals or gaskets that show wear. When the timing cover is removed, visually inspect the timing belt/chain, tensioner and pulleys for wear — replacing worn items at the same time avoids repeat labour. Follow the vehicle manufacturer’s service manual for engine support points and safe removal of ancillary components.
Why This Part Most Often Fails
- Plastic Degradation: Heat cycles and engine bay exposure cause plastic covers to become brittle and crack over time.
- Impact Damage: Road debris or improper handling during previous repairs can crack or break the cover.
- Fastener Or Clip Failure: Broken clips or stripped threads allow the cover to vibrate and eventually detach or crack.
- Oil Contamination: Persistent oil leaks can deteriorate plastic and seals, accelerating failure.
Choosing the correct OE numbers (9641898280, 9640454780, 0320T6) ensures compatibility and reduces fitting issues. This part is intended for professional fitment by mechanics or experienced DIYers familiar with timing system procedures.
