How often should Nissan Tiida spark plugs be replaced?
1 Answers
Nissan Tiida spark plugs should be replaced every 40,000 kilometers. The spark plug is a crucial component of a gasoline engine's ignition system. It introduces high-voltage electricity into the combustion chamber and creates a spark by jumping the electrode gap, thereby igniting the combustible air-fuel mixture in the cylinder. If a spark plug is damaged, it can directly cause 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, scarring or damage at the top, or melted and eroded electrodes all indicate that the spark plug is damaged and should be replaced. Steps to replace 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 everything is cleaned thoroughly. 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 high-voltage distributor wires in the correct firing order and secure the cover.
