What do the Spark Plugs do?

A spark plug converts the electricity current supplied by the ignition coil (and the distributor on older cars) into a spark to ignite the fuel and air mixture inside the engine. It leads the mixture to combust and in turn power the car along. Spark plugs are directly situated inside the cylinder head and are connected to the ignition leads on the outside of the engine. The other end of the spark plug, which protrudes into the engine's cylinder, has an electrode that produces the actual spark.

How do you know there is something wrong with a Spark Plug?

When starting the car is problematic.
When the engine cuts out after starting.
When the engine does not run smoothly (the engine misfires).
When the car vibrates excessively.
When the 'Check Engine' light on the car's dashboard is on.
When the car's fuel consumption is higher than usual.

When should you consider a Spark Plug replacement?

Over time, carbon residue can build up on the electrodes that provide the spark inside the engine's cylinder. This is also known as 'carbon fouling' of the spark plugs. Equally, oil deposits can build up on the spark plugs. Usually this can be resolved by cleaning the spark plugs.

Alternatively, the spark plugs can also melt due to an abnormally increased temperature in the engine's cylinder. In all these cases it is not the spark plug that is faulty, but rather it points to issues with the engine and fuel system.

Sometimes, spark plugs just wear out due to prolonged use, at which point they should be replaced to ensure a continued and correct combustion of fuel. An engine with a faulty spark plug will not run smoothly and can potentially lead to further engine damage, it is therefore important that issues with the spark plugs are addressed professionally and timely.

Should you experience problems with a spark plug then it is advisable to have it inspected and, if necessary, have it replaced. Remember the spark plugs should always be serviced as and when stipulated in the guidelines set out by your car's manufacturer.

What happens during a Spark Plug replacement?

Mechanic will read the ECU for possible fault codes related to the ignition system.
Mechanic will inspect the ignition system and spark plugs.
Mechanic will use a spark tester to check each spark plug in detail.
If necessary, the mechanic will run a compression test on each cylinder.
If necessary, the mechanic will replace the faulty spark plug(s).
Mechanic will advise if any other parts need to be replaced.
Mechanic will check if the ignition system works correctly again and will test drive the car.
Mechanic will make any adjustments if necessary.
