How to Replace Spark Plugs in a Tiida?

[VonHaven]

Tiida spark plug replacement procedure: Open the hood, lift the plastic engine cover, remove the high-voltage distributor wires, and 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 any external debris like leaves or dust, and ensure thorough cleaning. Place the new spark plugs into the spark plug holes, hand-tighten them for a few turns, then use the socket to tighten them further. Reinstall the removed high-voltage distributor wires according to the firing order, and secure the cover. Spark plug replacement interval: Under normal maintenance conditions, replace spark plugs every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it's advisable to follow the owner's manual. For reference, platinum spark plugs should be replaced at 40,000 kilometers, standard nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers.
