How often should the spark plugs be replaced on a Haval M6?

[FranciscoAnn]

Haval M6 spark plugs should be replaced approximately every 40,000 kilometers. Under normal maintenance conditions, spark plugs are typically replaced between 40,000 to 60,000 kilometers of driving. However, this may vary depending on the brand and engine type, so it's recommended to follow the user manual. The following standards can be referenced for maintenance replacement: platinum spark plugs should be replaced at 40,000 kilometers, ordinary nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000-80,000 kilometers. Spark plug replacement steps: Open the hood, lift the engine's plastic 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. During removal, 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 according to the firing order, and then secure the cover plate.
