How to Replace the Spark Plugs of the Toyota Sienta?

Model: Toyota Sienta Npc80 - Years 2003-2015
Part: Spark plugs

To replace the spark plugs of the Toyota Sienta, open the hood to access the components inside the engine compartment: you will need to detach the plastic cover from the top of the engine block to access the underlying components. It will be necessary to unscrew the bolts securing the injectors in their place, disconnect them, and remove them to access the spark plugs underneath: these should be removed with the appropriate socket wrench and replaced with new replacement parts, reassembling the injectors and the upper engine cover.
