Replacing the Engine Spark Plugs

Model: Mazda 6 GG, MK 1 - Years 2002-2008
Part: Spark plugs

For safety, disconnect the negative terminal of the battery. Carefully remove the plastic cover protecting the engine by simply lifting it upwards. To avoid confusing the cables, disconnect only the first spark plug. Using a 10mm socket wrench, unscrew the sealing nut of the first spark plug and pull the connector upwards. At the bottom of the well is the first spark plug. Before proceeding with the disassembly, carefully clean the wells with compressed air to remove any dirt that could fall into the combustion chamber. Using the appropriate spark plug tool, which has a rubber gripping device, gently insert it onto the spark plug head and unscrew it. Proceed carefully to avoid dropping 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, ensuring it screws in well without forcing.

To bleed the clutch on a Renault Clio, open the bonnet to access the components located in the engine bay: here, you will need to undo the screws that secure the battery in its housing, the intake manifold, and the coolant reservoir. This will allow you to locate the pipe through which the brake fluid flows: by inserting the other end of the pipe into a container, you can press the clutch pedal to expel all the fluid until it fills the container.
