Model: Vauxhall Astra Astra H - Years 2004-2010
Part: Spark plugs

Perform this maintenance with the engine cold. Remove the engine cover and unscrew the fastening screws of the plastic block containing the ignition coils and spark plug leads. Before unscrewing the spark plugs, it is advisable to thoroughly clean the spark plug seats to prevent any debris from entering the cylinders once the plugs are removed. Proceed to remove the spark plugs and install the new ones (do not exceed the tightening torque); reposition the leads and ignition coils and tighten the relevant fastening screws.
