Must Spark Plugs Be Replaced If They Leak Electricity?

[VanTalia]

Spark plug breakdown, major head leakage, spark plug air leakage, and spark plug oil leakage are common phenomena when replacing spark plugs. If a spark plug is damaged by electrical leakage, both the spark plug and the ignition coil's ignition wire need to be replaced. 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 to create 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 cylinder wires, but over the past decade, most car engines have been modified to connect the ignition coil directly to the spark plug. Steps for replacing spark plugs: Open the engine hood, lift the engine's plastic cover, and remove the high-voltage distributor wires. 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 external debris like 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 distributor wires according to the firing order, and secure the cover.
