How Often Should the Spark Plugs of Wuling Hongguang Be Replaced?
2 Answers
It is recommended to replace the spark plugs of Wuling Hongguang S every 40,000 kilometers. Under normal maintenance conditions, car spark plugs should be replaced after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine, so it is advisable 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, and remove the high-voltage distributor wires. 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 they are thoroughly cleaned. 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 secure the cover plate.
I've driven the Wuling Hongguang for a while. Spark plugs are wear-and-tear parts, generally recommended to replace every 30,000 km or so - don't wait too long. The manufacturer's recommended interval is probably in the user manual, around 30,000 to 50,000 km depending on the type of spark plug - copper-core ones wear out faster. If you frequently drive short distances in city traffic with lots of stop-and-go, or operate in dusty conditions, the spark plugs will degrade quicker and may need inspection before 30,000 km. I remember once my car suddenly lost acceleration power and had cold start slipping - turned out the spark plugs were heavily carbon-fouled. After replacement, it ran much smoother immediately. Bottom line: replacing early brings peace of mind. Delaying until problems arise may affect fuel efficiency or even engine lifespan. I have the repair shop do a quick check every 10,000 km to avoid regrets.
