How Often Should the Spark Plugs of SAIC Volkswagen Lavida Hatchback Be Replaced?
2 Answers
Under normal maintenance conditions, the spark plugs of SAIC Volkswagen Lavida Hatchback should be replaced every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it is recommended to follow the user manual. You can refer to the following standards 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 wires, and 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 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 wires in the firing order and secure the cover.
I've driven a SAIC Volkswagen Lavida for six years, and spark plug replacement should follow the official recommendation, usually every 30,000 kilometers or two years. If spark plugs aren't replaced for a long time, electrode wear can cause delayed ignition, sluggish acceleration, increased fuel consumption, and even engine vibration. From my experience, if you frequently drive short distances or in traffic jams, spark plugs wear out faster, so it's best to shorten the replacement interval. During regular maintenance, have the technician check the electrode gap with a tool—if it's too wide or too narrow, replace them immediately. Don't skimp on time or money; preventive maintenance makes the car more durable and fuel-efficient.
