How many kilometers should a new car drive before replacing the spark plugs?
1 Answers
Under normal maintenance conditions, a new car should have its spark plugs replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it is recommended to follow the instructions in the user manual for replacement. Maintenance replacement can be based on the following standards: Replace platinum spark plugs at 40,000 kilometers, replace ordinary nickel alloy spark plugs at 20,000 kilometers, and replace iridium spark plugs at 60,000 to 80,000 kilometers. Damaged spark plugs may exhibit the following symptoms: difficulty starting, reduced power, excessive exhaust emissions, and increased fuel consumption. If these symptoms occur, the spark plugs should also be replaced. Steps for replacing spark plugs: Open the engine hood, lift the plastic cover of the engine, remove the high-voltage branch lines, and mark each cylinder's position to avoid confusion. Remove the spark plugs one by one using a spark plug socket. During removal, check for any leaves, dust, or debris on the outside and ensure they are thoroughly cleaned. Insert the new spark plugs into the spark plug holes, rotate them a few times by hand, and then tighten them with the socket. Reinstall the removed high-voltage branch lines in the firing order and secure the cover plate.
