What Tools Should Be Used to Remove and Install Engine Spark Plugs?

[CarolineLynn]

To remove and install engine spark plugs, a dedicated spark plug socket should be used, and the engine must be cooled before removal. First, clean the ignition coil and surrounding areas of dust and oil, then disconnect the wiring harness plug of the ignition coil and use the socket to unscrew the fixing bolts of the ignition coil. Here are additional details: 1. Usage Method: Pull out the ignition coil. For some vehicle models, the ignition coil is sealed with rubber against the cylinder block, requiring some force to remove. After removing the ignition coil, use the socket to loosen the spark plug. Once the spark plug to be removed is loosened, use a thin, flexible tube to blow away any debris around the spark plug to prevent dirt from falling into the combustion chamber when the spark plug is removed. 2. Spark Plug Socket: Automotive spark plug sockets generally come in four specifications: 1/2DR*16, 21, 3/8DR*16, 21. There are also universal spark plug sockets, typically available in 16mm and 21mm sizes.
