CONVENTIONAL SPARK PLUG CHANGING AND
MAINTENANCE INSTRUCTIONS
2/3
WARNING
Under certain circumstances, the failure of a spark plug to operate properly may be due to problems with the wire:
either dirt on the wire deviates the spark to earth or the wire contacts are cracked or sulphated, impeding the
electric potential to reach the spark plug.
2. Remove the used spark plugs from the engine with a socket wrench.
3. Insert the new spark plugs (dry, without MOLIKOTE) into their housings in the engine, avoiding as far as
possible to touch the ceramic portion of the same and remove any residual dirt from the surface of this portion,
using an absorbent paper. You can start screwing on the spark plugs manually, making sure the washer is
correctly placed in its seat. Finally, use the torque wrench to fasten the spark plug to the appropriate nominal
tightening torque, i.e. 4.8kgm.
4. Reconnect the wires of the secondary to the spark plugs, using light pressure to click them in place. Now, you
can restart the engine.
5. To prevent the formation of corrosion or sulphation, apply silicone grease onto the connectors and terminals,
which prevents moisture from getting in. Such types of grease include: Dow Corning
DC-4, G.E. G-623 or GC Electronics Z5. Also apply a small amount of grease onto the wire connector and coil.
