DIY – How to change spark plugs in your car step by step @KenyanTraffic

Depending on the type of spark plug you have, you might need a spark plug socket specific to that component. To change the spark plugs in your car, you’ll need:

• A socket wrench
• A gap gauge
• Spark plug wire puller
• Torque wrench
• Swivel socket
• Needle-nose pliers
• Rags to wipe up grease and oil

Begin by taking off the plastic cover on the spark plug and air cleaner component from the top of your engine. If you have to take out vacuum hoses, label them so you can reinstall later without issue. Clean the top of your engine if you have a four-cylinder (if you have a V engine you’ll clean the banks area) before you take out any other parts.

Blow compressed air on the ignition coils so dirt and debris don’t fall in the cylinders. Next, remove your ignition coil be pulling the locking tab. Take the connector of your coil and disconnect the coil bolt so you can remove the whole coil and boot component. If your vehicle doesn’t feature a COP ignition, the spark plug wire will have a boot connected to the plug so you can use the spark plug wire puller to remove the boot.

Let your engine cool down before you remove the spark plugs. Take your spark plug wire puller, position the boot far down to the end of the plug, twist it, and remove with counter-clockwise rotating motions. Use your swivel socket as needed. You’ll also want to gap your new spark plugs before you install them according to the manufacturer’s instructions.

Use a torque wrench based only on the manufacturer’s torque specs to ensure you have the proper amount of torque, as too much will misshape the plug. Finally, remember to apply lube to the boot of the new spark plug before you reinstall the coil to inhibit misfires and make any future changes easier. Reinstall your coil, electrical connector, and bolt, then install the vanity cover and air cleaner. Now, you should be all set and ready to fire your engine up.
