How Often Should Nissan Tiida Spark Plugs Be Replaced?
1 Answers
Nissan Tiida spark plugs should be replaced every 40,000 kilometers. Spark plugs are a crucial component of a gasoline engine's ignition system. They introduce high-voltage electricity into the combustion chamber, causing it to jump the electrode gap and produce a spark, thereby igniting the combustible air-fuel mixture in the cylinder. If a spark plug is damaged, it can directly lead to issues such as electrical leakage in the vehicle's ignition system, increased fuel consumption, reduced power output, and most notably, difficulty in ignition, which affects the vehicle's normal operation. Severe spark plug erosion—indicated by pitting, damage, or melted electrodes—signifies that the spark plug is worn out and should be replaced. Steps for replacing spark plugs: Open the hood, lift the engine's plastic cover, and remove the high-voltage ignition 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 ignition wires in the correct firing order, then secure the cover.
