Removal and installation of spark plugs, ignition modules and high-voltage wires (Opel Corsa C)

1. A general description of the ignition system is given in Section 1. Detailed information about spark plugs, high-voltage wires and the procedure for replacing them is given in Section 22 Chapter 1. This section describes in detail the operations for removing and installing the ignition module.

Note: Disassembly and repair of the module in a regular repair shop is not performed - the module is replaced entirely. Ignition coils are not subject to repair.

2. If equipped, remove the ignition module cover by sliding it in the direction indicated by the arrow (see accompanying illustration).



3. Disconnect the electrical wiring from the ignition module and unscrew the 2 central bolts securing the module (see accompanying illustration).





4. To remove the ignition module, use special handles that are screwed into the central threaded holes (see illustration 5.2). If they are not available, you can use a pair of long bolts of a suitable diameter with the appropriate thread pitch.

Note: These handles are also used to prevent burns to your hands when removing the ignition module on a hot engine.

5. When removing the ignition module, it is necessary to pull it straight up, try not to allow it to twist to avoid damaging the spark plug connectors.

6. Installation is carried out in reverse order.
