How to Replace the Spark Plugs on a Citroën C1

Model: Citroen C1 MK 1 - Years 2005-2014
Part: Spark plugs

To replace the spark plugs on this vehicle, follow the instructions in this description. First, open the bonnet, then detach the plastic clips securing the upper engine cover by loosening the hose clamp on the air duct. This will give you access to the engine head and the coils. Disconnect the electrical connector after safely disconnecting the negative and positive terminals of the battery. Use a socket wrench to remove the coils and then unscrew all four spark plugs. Install the new spark plugs, refit the coils, and reconnect the electrical connectors.
