So what does a spark plug do?
Spark plugs are utilised as a source of ignition at the conclusion of the compression cycle in gasoline engines. The spark ignites the gas, causing the piston to move along the cylinder, which makes the crankshaft to revolve. The engine would not be able to run without the spark plug.
Most current spark plugs are constructed of ceramic and iridium or platinum and are expected to run for 20,000 kms or more. However, they should be evaluated every 10,000 kms or so to give you a sense of the engine’s condition.
When is it time to change my spark plug?
Consult your owner’s handbook for the suggested intervals for changing your spark plugs. If you can’t discover a recommendation, remove them and inspect their condition. It doesn’t take long and offers you an idea of how the engine is working.
A good spark plug for example, will have light brown electrodes and an insulator with no signs of melting, wear, or deposits. If you see oil deposits, the piston rings may be worn. White deposits may indicate that the plug is not of the proper heat grade, whereas carbon deposits indicate a rich mixture or a poor ignition.
How to change it yourself?
- Ascertain that the engine is cool and that you have the necessary equipment.
- Parts may need to be removed to obtain access to the plugs.
- Concentrate on one spark plug at a time. With a twisting motion, remove the ‘boot’ from the top of the plugs.
- To remove the plug, use a spark plug socket and ratchet.
- Adjust the spacing of the new spark plug (if necessary/possible), treat the threads with an anti-seize compound, and attach the plug, taking care not to cross-thread or over-tighten it.
Why is it important to change your spark plugs?
If the engine is to run smoothly, the spark plugs must be properly maintained. If you ignore them, you may encounter a number of problems.
To begin, you may have difficulty starting the engine. You’ll have to flip it over numerous times before it fires, which may eventually flatten the battery. Once started, the engine may have a rough idle and feel ‘lumpy,’ or it may misfire, indicating that not all cylinders are performing properly.
Misfiring should be addressed promptly since it risks causing damage. A defective spark plug may also result in greater fuel consumption and decreased engine output and should be addressed as soon as possible.
