How to Deal with a Stubborn Spark Plug?
1 Answers
If a spark plug is difficult to loosen, it is recommended to spray some screw loosening agent, let it soak for a while, and then try to unscrew it. Gently tighten and loosen it repeatedly to free it up. However, avoid applying excessive force. If it still won't budge, try turning it in the opposite direction and repeat the process a few times until it loosens. The spark plug is a crucial component of a gasoline engine's ignition system. It introduces high-voltage electricity into the combustion chamber, causing it to jump across the electrode gap and generate a spark, thereby igniting the combustible air-fuel mixture in the cylinder. Spark plugs are installed on the side or top of the engine. Early spark plugs were connected to the distributor via ignition cables, but in the past decade or so, most car engines have switched to direct connection between the ignition coil and the spark plug. Under normal maintenance conditions, spark plugs should be replaced every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it's advisable to follow the owner's manual. For reference, here are some general replacement intervals: platinum spark plugs at 40,000 km, standard nickel alloy spark plugs at 20,000 km, and iridium spark plugs at 60,000 to 80,000 km.
