How often should the spark plugs of Nissan Sylphy be replaced?
1 Answers
Nissan Sylphy spark plugs should be replaced every 40,000 kilometers. The spark plug is a crucial component of the gasoline engine's ignition system. It introduces high-voltage electricity into the combustion chamber, causing it to jump the electrode gap and generate a spark, thereby igniting the combustible air-fuel mixture in the cylinder. If the spark plug is damaged, it can directly lead to various issues such as leakage in the vehicle's ignition system, increased fuel consumption, and reduced power. The most significant problem is difficulty in ignition, which affects the normal operation of the vehicle. Severe erosion of the spark plug, such as blistering at the top, damage, or melted and eroded electrodes, indicates that the spark plug is damaged and should be replaced. Steps for replacing spark plugs: Open the hood, lift the plastic cover of the engine, and remove the high-voltage distributor wires. Mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for external debris like leaves or dust and ensure they are thoroughly cleaned. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to tighten it further. Reinstall the removed high-voltage distributor wires in the correct firing order, and then secure the cover.
