Will the Car Shake If the Spark Plugs Are Not Tightened Properly?
1 Answers
If the spark plugs are not tightened properly, the car will shake. Therefore, when replacing spark plugs, the torque applied should be based on the required torque for the specific spark plug being used. Different sizes of spark plugs require different levels of torque. Steps for replacing spark plugs: 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. While removing them, check for any external debris such as leaves or dust and ensure everything is cleaned 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 high-voltage ignition wires in the correct firing order and secure the cover. Spark plug replacement intervals: 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 owner's manual. The following standards can be used as a reference for maintenance and replacement: Platinum spark plugs should be replaced every 40,000 kilometers, standard nickel alloy spark plugs every 20,000 kilometers, and iridium spark plugs every 60,000 to 80,000 kilometers.
