How do you replace the spark plugs on a Smart Roadster?

Model: Smart Smart 452, Roadster - Years 2003-2005
Part: Spark plugs

To replace the spark plugs of the Smart Roadster, you need to open the rear hatch of the car so that you can access the engine located underneath it. Here, it will be possible to disconnect the connectors connected to the injectors, so that they can then be removed from their housings by unscrewing the fixing bolts. After the injectors have been removed, the underlying spark plugs can be removed from their housings and replaced with new replacement parts. After replacing the spark plugs, the injectors can be reinserted, connected and fixed properly.
