Introduction
The spark plugs are changed every 30,000 km as a preventative measure. This operation is very simple on the Skoda Felicia because access is really ideal.
Parts
-
-
The spark plugs are located at the front of the engine (red rectangle), they will be changed one by one to avoid reversing the ignition cables
-
disconnect the ignition harness
-
We do not pull on the wire, we must take the bundle by its end.
-
clean the spark plug well with a blower (a can of computer air may possibly do the trick)
-
-
-
unlock the spark plug with the ratchet wrench, small extension and 16mm long socket (1/2 turn should be enough)
-
finish unscrewing by hand
-
remove the spark plug
-
-
-
compare spark plugs and ensure compatibility
-
we see here that the original spark plug has 3 electrodes while the new one has 4: this has no importance and no impact on the performance or consumption of the engine (we can choose a spark plug with 1, 2, 3 or 4 electrodes)
-
refer to the candle's technical data sheet or its packaging in case of doubt
-
-
-
introduce the new spark plug and hand tighten using the 16mm extension and socket only
-
There should be no resistance at first. Do not insist if it is too hard or you may damage the thread.
-
finish tightening with the torque wrench, torque of 28N.m
-
Put the beam back in place by pressing on it
-
A thin layer of dielectric grease can be applied to the ceramic portion and spark plug tip before reconnecting).
