First, turn off the engine and wait until it cools down. Open the hood and locate your car's spark plugs at the level of the cylinder block.

After removing the candle, clean it thoroughly with a wire brush. You can also use a special spark plug cleaner.

Now that the spark plug is clean, you can thoroughly check its condition. If you notice deposits, cracks, or burn marks, the spark plug must be replaced. To replace spark plugs, you can refer to our manual if you are an outstanding mechanic, or go to a mechanic and have him do the job.
