How many kilometers should the spark plugs of the Sagitar 1.6 be replaced?
2 Answers
The spark plugs of the Sagitar 1.6 should be replaced every 40,000 to 60,000 kilometers. Spark plugs are a crucial component of the gasoline engine's ignition system. They introduce high voltage into the combustion chamber and create a spark by jumping the electrode gap, thereby igniting the combustible mixture in the cylinder. Steps for replacing spark plugs: Open the engine hood, lift the plastic cover of the engine, and remove the high-voltage distributor wires. Mark the position of each cylinder to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any 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 removed high-voltage distributor wires in the firing order and secure the cover.
I've been driving my Sagitar 1.6 for over five years. The manufacturer recommends replacing spark plugs every 20,000-30,000 km. I remember last time when my car reached 28,000 km, it started idling roughly. When we opened it up, the electrodes were all burnt black. The mechanic said this model uses standard nickel alloy spark plugs, and if you frequently encounter city traffic jams, it's better to check them every 25,000 km. Don't go for cheap gas - low-quality fuel tends to cause carbon buildup on spark plugs. When replacing, it's recommended to change the whole set rather than just one or two, otherwise it may affect ignition balance. After replacement, I clearly felt the throttle became more responsive, and fuel consumption dropped by about 0.5 liters.
