Replacing faulty spark plugs on an Astra. Let's see how to replace them.

Lift the bonnet and secure it. Disconnect the battery terminals. Remove the central cover of the engine soundproofing panel, unscrewing the screws that secure the coil bar to the engine head with a screwdriver.

Unscrew the spark plugs with a socket spanner and pull them out of the head. Use the extension of the socket spanner to guide the new spark plugs into the engine head, tighten them, and connect the ignition coils to each new spark plug.

Finally, close the bonnet and test the car's proper functioning. Replace all damaged spark plugs.
