Why is the spark plug too tight to remove?
1 Answers
The reason why the spark plug is too tight to remove is that it was over-tightened during installation. Therefore, when replacing the spark plug, the force applied should be based on the required torque for the specific spark plug being used. Spark plugs of different sizes require different amounts of force. Steps for replacing the spark plug: Open the hood, lift the plastic cover of the engine, and remove the high-voltage ignition wires. 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 any external debris such as leaves or dust, and make sure to clean them thoroughly. 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 ignition wires according to the firing order, and then secure the cover. Spark plug replacement interval: 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 is recommended to follow the user manual. The following standards can be used as a reference for maintenance and replacement: Platinum spark plugs should be replaced every 40,000 kilometers, ordinary nickel alloy spark plugs every 20,000 kilometers, and iridium spark plugs every 60,000 to 80,000 kilometers.
