Steps for Changing Spark Plugs in a Car
Step 1: Locate the Spark Plugs
The first step is to locate the spark plugs in your car. Spark plugs are typically located in the engine compartment, near the top of the engine. They are usually marked with a "spark plug" symbol.
Step 2: Disconnect the Battery
Before you can start working on the spark plugs, you need to disconnect the battery. This will help to prevent any accidental sparks from causing a fire.
To disconnect the battery, locate the negative battery terminal. There will be a black wire connected to this terminal. Use a wrench to loosen the nut that secures the wire to the terminal. Once the nut is loose, you can disconnect the wire from the terminal.
