How Many Kilometers Should the Spark Plugs of a Van Be Replaced?
2 Answers
Under normal maintenance conditions, the spark plugs of a van should be replaced every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type. It is recommended to follow the guidelines in the user manual. The following standards can be referenced for maintenance and replacement: 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. Steps for replacing spark plugs: Open the engine 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, check for any external debris such as leaves or dust and ensure they are thoroughly cleaned. 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 according to the firing order and secure the cover.
I've been driving a van for many years, and the mileage for spark plug replacement depends on personal driving habits and vehicle condition. Generally, they should be inspected and replaced every 30,000 to 50,000 kilometers, especially for vans frequently carrying loads or running long distances, as spark plugs wear out faster. The last time I replaced them was just over 30,000 kilometers when the car started shaking a bit upon ignition. The mechanic said the spark plug electrodes were severely worn, and fuel consumption had increased. Remember to check the manual; manufacturers usually recommend replacement around 40,000 kilometers, but don't wait until they completely fail. Regular maintenance saves trouble—inspect the ignition coils and wiring harness when replacing spark plugs to ensure the ignition system works properly. If you notice sluggish acceleration or slow starts during daily driving, it's a sign to address the issue early.
