2 Answers
Wuling Hongguang S spark plugs are recommended to be replaced every two years or 40,000 kilometers. Under normal maintenance conditions, car spark plugs should be replaced after driving 40,000 to 60,000 kilometers, but this may vary depending on the brand and engine. It is recommended to follow the user manual. The following standards can be referenced for maintenance and 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 to 80,000 kilometers. Steps for replacing spark plugs: Open the hood, lift the plastic cover of the engine, remove the high-voltage distributor wires, and mark the position of each cylinder to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. When removing them, check for any external debris such as leaves or dust, and make sure to clean them thoroughly. Place the new spark plugs into the spark plug holes, hand-tighten them a few turns, and then use the socket to tighten them further. Reinstall the removed high-voltage distributor wires in the firing order and secure the cover.
I've been driving the Wuling Hongguang S for freight transport for five or six years. The factory spark plugs on this car basically need to be replaced every 30,000 kilometers. It mainly depends on road conditions and driving habits. For someone like me who often carries heavy loads on mountain roads, I can feel the acceleration weakening after just over 20,000 kilometers. When the mechanic took them out, the electrodes were almost worn flat. Don't forget to check the spark plug gaps during regular maintenance - if there's too much carbon buildup, starting becomes difficult, especially in winter. Ordinary nickel alloy plugs are cost-effective but have a shorter lifespan. If you want more durability, you can switch to platinum plugs. Although they're more expensive, they can last up to 50,000 kilometers. Remember, don't try to save a few hundred bucks - if the car breaks down halfway, it'll cause even more trouble.
