Replacing Spark Plugs and Ignition Coils

Model: Mazda 6 GH, MK 2 - Years 2008-2012
Part: Spark plugs

For safety, disconnect the negative terminal of the battery. Gently remove the plastic cover protecting the engine by lifting it upwards. To avoid confusion with the wires, disconnect only the first spark plug. Using a 10mm socket, unscrew the retaining nut of the first spark plug and pull the boot upwards. At the bottom of the well is the first spark plug. Before proceeding with removal, thoroughly clean the wells with compressed air to eliminate any dirt that could fall into the combustion chamber. Using the appropriate spark plug socket, 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 socket and turning it gently, ensuring it screws in properly without forcing. Remove the coils and replace them with new ones.

Tips on How to Change the Glow Plugs on 1.3 MJT Engines

The 1.3 CDTI engine is used in many models from Fiat, Lancia, Opel, and Suzuki, making glow plug wear a common issue. The glow plugs are located at the front of the engine, just in front of the rocker cover. Simply remove the engine cover to locate them. A quick functionality check can be done by disconnecting the connector and gently touching the glow plug with an electric wire connected to the positive terminal of the battery: if a spark occurs, the glow plug is fine. A problem that may arise during replacement is that the glow plug may not unscrew. It is advisable to spray some penetrating oil and let it sit overnight before unscrewing it with an 8 mm socket. Before installing the new one, apply some special grease and do not exceed the torque specification.
