Spark Plug Replacement Service

Where do spark plugs come from, and how do they work?

Spark plugs are one of the critical components of your vehicle’s ignition system. It’s their job to ignite fuel and air in your car, giving your engine power to propel you. The spark plug creates a spark at the right moment during the engine’s combustion cycle by taking high voltage electricity from the ignition coil. The engine’s best mix of power, fuel efficiency and low emissions is provided by this. Performance issues can be caused by the wear and tear on the spark plug’s electrode at the end.

When is the right time for a spark plug replacement?

Replacement should follow the maintenance schedule of the vehicle manufacturer listed in the vehicle’s owner’s manual. Regular replacement is required at 45 000, 90 000 or 150 000 kilometres depending on the car. It is possible, though not expected, that a spark plug might fail before the scheduled maintenance service intervals in some cases.

Multiple symptoms can be caused by avoiding spark plug replacement.

  • It’s challenging to get your vehicle started.
  • There is an engine light for a misfire code.
  • There is a check engine light that goes off, for a misfire, during acceleration. This can damage the engine and result in costly engine repairs.
  • It reduces fuel economy or power.
  • Rough idling or unexplained engine vibration.
  • It failed regulated emission testing.

Even if there is only one faulty spark plug, the mechanic should always replace them in sets. The majority of engines need at least four, six, or eight spark plugs.

Change your spark plugs regularly to increase the performance of your engine. Malfunctioning engine spark plugs can cause poor fuel economy.

What do mechanics do when spark plugs are replaced?

The cylinder head of the engine has spark plugs in it. Most cars have a single plug per cylinder. A four-cylinder engine will have four plugs, a six-cylinder engine will have six plugs, and an eight-cylinder engine will have eight plugs. The mechanic will:

  • Have the correct replacement plugs for your car from the auto parts dealer.
  • Diagnostic trouble codes relating to worn spark plugs should be pulled.
  • Search for clues that the engine is misfiring can be found by removing the original spark plugs.
  • Use a torque wrench is needed to install new plugs.
  • Conduct a road test to confirm the regular operation of your car.

Is it safe for drivers to drive with worn spark plugs?

Suppose spark plugs are worn to the point of causing engine misfiring. In that case, they can cause engine damage and overheating the catalytic converter. This could lead to the need for extensive engine repair. Regardless of the plugs’ age or mileage, the mechanic should inspect the plugs for defects if the engine misfires or runs poorly. Spark plug failure will not usually prevent the engine from running. Still, in cases of extreme wear, you may experience a decrease in engine performance through limits on the speed at which you can drive the car. If the schedule says a professional mechanic needs to replace the plugs, it’s best to do it quickly.

It is advisable to keep in mind the below during a spark plug replacement.

  • There is a possibility that high-speed driving will accelerate spark plug wear. If the car is being operated in severe conditions, consider earlier than required inspection and tune-up.
  • Plugs should always be promptly replaced per the manufacturer maintenance schedule even if they appear to be working perfectly.
  • Your vehicle may have spark plug wires instead of coil-on-plug systems. In that situation, the mechanic should replace the wires at the same time. The cost of your repair could go up because of this.
  • When doing a spark plug replacement, your vehicle may need additional parts, such as an ignition coil, which will add to the repair cost.
  • The intake manifolds on some engines have to be removed while the spark plugs are replaced. This could lead to an increase in the cost of the repair.
  • Ignition system issues may be caused by a leaking valve cover gasket, which allows oil to contact the spark plugs. Along with the spark plugs, wires or coil, the valve cover gasket needs to be replaced. This will make the repair cost more expensive.
