Spark plug installation process:

1.Prepare tools and materials: Ensure the correct type of spark plug is available, as well as the necessary tools such as wrenches, spark plug wrenches, ignition wire pliers, etc.
2.Determine the position of spark plugs: Based on the specific model and engine layout of the vehicle, locate the spark plug location that needs to be replaced.
3.Disconnect the battery: For safety reasons, it is best to disconnect the negative cable of the vehicle before replacing the spark plug.

4.Dismantling ignition wire: Use ignition wire pliers to gently rotate and pull out the ignition wire, being careful not to pull the ignition wire itself to avoid damage.
5.Dismantling old spark plugs: Use a spark plug wrench to unscrew the old spark plugs, being careful not to use too much force to avoid damaging the spark plug holes.
6.Clean spark plug holes: Use air pressure or spark plug cleaner to clean the spark plug holes and ensure that there are no impurities.
7.Install new spark plugs: Manually screw the new spark plugs into the spark plug holes, and then tighten them appropriately using a spark plug wrench.
8.Connect the ignition wire: Insert the ignition wire into the new spark plug, ensuring that the plug is completely attached.
9.Repeat the above steps: If multiple spark plugs need to be replaced, repeat the above steps until all replacements are completed.
10.Connect the battery: Finally, reconnect the negative cable.
11.Start the engine: Start the engine and check for proper operation to ensure successful replacement of the spark plug.
