Replacing Engine Spark Plugs

Model: Saab 9 3 MK 2 - Years 2002-2014
Part: Spark plugs

Disconnect the ECU connector. Carefully remove the plastic cover protecting the engine. To avoid mixing up the cables, disconnect only the first spark plug. Using a 10mm socket, unscrew the retaining nut of the first spark plug and pull the boot upwards. The first spark plug is located at the bottom of the well. Before proceeding with the removal, thoroughly clean the wells with compressed air to eliminate any dirt that could fall into the combustion chamber. Using the appropriate spark plug tool, which has a rubber grip, gently insert it onto the spark plug head and unscrew it. Be careful not to drop any foreign objects into the well. Replace the spark plug with one of the same model, carefully inserting it into the well, always using the appropriate tool, and turn it gently while ensuring it threads correctly.
