How to Replace the Spark Plugs on a Smart 453?

Model: Smart Smart 453 - Years 2014-2022
Part: Spark plugs

To replace the spark plugs on a Smart 453, open the rear hatch of the boot and remove the carpet that serves as flooring. Once the carpet is removed, loosen the bolts securing the protective panel above the engine compartment. Here, move all the coils to use the appropriate T-key with a socket joint to extract the spark plugs from their housing. When the old spark plugs are removed, replace them with a new spare part, reinstalling all previously removed components.
