Description
Upper timing cover for Citroën and Peugeot 1.6 HDi engines of your favourite car.
This upper timing cover (OE references 9651560180 / 0320T6) is designed to protect the timing belt/chain area from dirt, debris and oil contamination while keeping the timing components correctly enclosed. Ideal for workshops and DIY mechanics working on 1.6 HDi engines, the cover restores correct fitment and helps maintain reliable operation of the timing system. The part offers direct fit for a range of Citroën and Peugeot models and is commonly sought by its product codes.

Fitment And Function
The upper timing cover protects the timing belt/chain and associated components (tensioner, idlers, camshaft seals) from external contaminants and helps direct lubrication and ventilation around the timing area. It is typically made from molded plastic and designed for precise alignment with engine mounting points to avoid interference with pulleys or sensors.
Installation Recommendations
- Work On A Cold Engine: Allow the engine to cool before beginning work to avoid burns and distortion of plastic parts.
- Prepare The Area: Remove any engine cosmetic covers, air intake components or accessory belts that obstruct access to the timing cover.
- Follow Removal Sequence: Loosen and remove retaining bolts in a controlled sequence. Keep fasteners in order for reinstallation.
- Inspect Sealing Surfaces: Clean mating surfaces thoroughly and remove old gasket residue. Replace any gaskets or seals as required.
- Check Timing Components: Inspect the timing belt/chain, tensioner and idler pulleys while cover is removed. If wear or play is present, replace the worn components at the same time.
- Torque And Alignment: Refit the cover and tighten bolts uniformly to the manufacturer’s recommended torque values. Avoid overtightening plastic threads—use threadlocker on metal studs if specified.
- Final Checks: Start the engine and check for unusual noises and oil leaks around the cover. Recheck fastener torque after a short test drive if recommended.
Why This Part Fails Most Often
- Aging And Brittle Plastic: Heat cycles and age can make the plastic cover brittle, leading to cracks or broken mounting tabs.
- Oil Contamination: Leaking camshaft seals, valve cover gaskets or other oil leaks degrade the cover and seals, causing poor fitment and contamination of the timing area.
- Impact Or Mechanical Damage: Road debris or improper handling during previous repairs can crack or deform the cover.
- Warping From Overheating: Excessive engine temperature can deform plastic parts and reduce sealing effectiveness.
Replacing a damaged upper timing cover prevents debris and oil from reaching the timing belt/chain, reducing the risk of premature belt wear or failure. For best results, fit this cover as part of a scheduled timing system service or whenever the timing components are inspected or replaced.
