How to Remove a Broken Spark Plug from a Car?

[VanAlejandro]

Detailed instructions for removing a broken spark plug from a car are as follows: 1. Use a 10mm T-handle wrench or an 8-9-10mm triple-square wrench to remove the broken spark plug: Grind the four edges of the broken spark plug screw extractor until the internal hex edges of the wrench can tightly grip it. Tap it downward firmly, then turn the wrench counterclockwise to remove the broken spark plug. 2. The standard for spark plugs typically uses heat range to characterize their thermal properties: The heat range of a spark plug indicates its ability to balance heat absorption and dissipation at the insulator skirt. The higher the heat range, the better the spark plug's ability to balance heat absorption and dissipation. 3. The construction of a spark plug consists of a slender metal electrode passing through a ceramic insulator: The lower part of the insulator is surrounded by a metal shell, which is screwed into the cylinder head with threads. A welded electrode at the bottom of the metal shell serves as a ground connection to the car body.
