What tool do I need to remove spark plugs?
You’ll need just a few tools to change out the spark plugs on your car. The most important tool is a socket wrench with an extension and a spark plug socket. Spark plug sockets come in two sizes: 5/8 inches and 13/16 inches. Most spark plug sockets have a rubber insert that holds the plug snugly in place.
How do you check the gap between spark plugs?
Gap all plugs before installation using the manufacturer’s specs. Always check the spark plug gap before installing it. Slide the correct wire gauge (or gap gauge) between the electrodes. The wire should drag slightly between them. If the gap is too small, open it with the gap gauge by prying up.
How do you replace a spark plug in a car?
Replace the wires if necessary. Insert the new plugs and tighten with your ratchet. Using the spark-plug socket, remove each plug from the engine, and replace each with a new spark plug. Tighten a bit (say, 1/8th of a turn) past hand-tight only.
What should I do if my spark plug is not working?
Check the repair guide. Take note it you feel considerable resistance while turning the spark plug counter-clockwise. You may need an additional small amount of penetrant and soaking time. If you encounter resistance, turn the spark plug clockwise and carefully work it back and forth.
Can a spark plug be removed from a boot?
The boot may need to be twisted back and forth to break the bond from the spark plug. Again, be careful. The metal terminal that connects to the spark plug inside the boot must be removed simultaneously with the boot to avoid damage.
