Timing belt

Manufacturers recommended timing belt replacement interval for Citroen C8 2.2 diesel is 120,000 km.
The experience of Citroen C8 owners confirms that timing belt does in fact last for the specified mileage.
Running your car in aggressive environments (e.g. salt, sand, etc.) causes timing belt to degrade faster and reduces its lifespan; under such conditions, the belt may need to be replaced sooner.
