Changing spark plugs tutorial: 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 external debris such as leaves or dust, and make sure to clean thoroughly. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, then use the socket to tighten further. Reinstall the removed high-voltage distributor wires according to the firing order, and snap the cover back into place. Spark plug replacement interval: Under normal maintenance conditions, replace spark plugs after driving 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it's recommended to follow the owner's manual. For reference, follow these maintenance standards: Platinum spark plugs should be replaced at 40,000 km, standard nickel alloy spark plugs at 20,000 km, and iridium spark plugs at 60,000-80,000 km. Replacing spark plugs before their replacement interval ensures the engine operates at peak performance.
Last time I changed the spark plugs in my car myself, and the whole process was quite rewarding. You need to prepare the tools in advance: a spark plug socket, a wrench, new spark plugs, as well as gloves and goggles—safety first. Wait until the engine cools down before starting. First, disconnect the ignition coil wires, then slowly unscrew the old spark plugs, being careful not to break them by applying too much force. Before installing the new spark plugs, check if the gap is correct, gently place them in, and use a torque wrench to tighten them to the manufacturer's recommended torque, usually around 15-20 Nm. Finally, reconnect the wires and start the engine to test if it runs smoothly. Why change spark plugs? It can make acceleration more responsive, reduce fuel consumption, and make driving much smoother. Don’t skimp on tools—a spark plug socket is essential; otherwise, you won’t be able to remove them. The whole process took me an hour, saving on labor costs, but remember to operate safely—avoid touching the hot engine or high-voltage wires. Regularly check every 40,000 km or two years to prevent major repairs.
