A loose plug may leak combustion gases, cause poor heat transfer, or worse, blow out. Tightening the plugs to the correct torque will prevent the plugs from seating loose in the cylinder head.

Look up the torque specification for your particular vehicle make and model in your repair manual. Tighten the spark plugs using a torque wrench.

On some cases, especially on aluminum type cylinder heads, using a thread insert is necessary for this repair.

You can use a thread-chasing tap for this.

If you have difficulty threading a plug by hand, most likely the thread on that cylinder needs to be cleaned.

Initially, install the spark plugs finger tight, without using any tools, to prevent stripping the threads.

Use this compound only if your repair manual recommends it.

Apply a dab of anti-seize compound on the upper half of the spark plug thread, the half farthest from the side electrode. Once you've diagnosed the old plugs, checked and set the gap on your new plugs, you are ready to install them: To install the spark plugs:Д¬lean the plug seats in the cylinder head with a clean cloth to remove dirt and grease. You may look up the spark plug recommended for your vehicle model in your car owner's manual or repair manual.

See the Spark Plug Heat Range section at the bottom of this post. Make sure you are installing the correct plugs for your application, including the correct heat range. Sometimes, it is necessary to replace the thread using a threaded insert, especially on engines with aluminum heads.If one or more threads on the cylinder head are damaged, you may fix the thread using a spark plug thread chaser.If necessary, examine the threads on the cylinder head as well. Look for thread damage or small metal fragments embedded between the threads.Examine each spark plug thread, especially those that were difficult to turn.If your spark plugs use a gasket, make sure all the gaskets came out as well. Or just use the brush if you don't have access to a bicycle pump but remove as much dirt or dust as possible.ДЇinish removing the spark plugs and place them in order on a workbench or similar surface, so that you know which plug belongs to which cylinder.If you don't have compressed air available, you can use a bicycle air pump and a soft brush.Remove any accumulated dirt or debris from around the base of the spark plug.Use more lubricant, if necessary, until the plug becomes loose but don't remove the plug just yet. Wait 15 minutes and turn the plug back and forth about 45 degrees. If the plug seems hard to turn, just turn it about 45 degrees counterclockwise and spray oil penetrant around the base of the plug. The socket has an external hex end so that you can use an open-end or box wrench as well.The spark plug socket has a bushing insert to protect the plug insulator and prevent the plug from falling off the socket when removing or installing the plug.Unscrew each spark plug a couple of turns counterclockwise using a ratchet, ratchet extension, and spark plug socket.On some models, you may need to use boot puller pliers to disconnect the wire from the spark plug. Pull the boot off the spark plug as you gently twist the boot back and forth.Twist it about 90 degrees to break the boot loose.Remove each spark plug wire or ignition coil from each spark plug.This will prevent you from mixing the wires during the installation process and cause engine performance problems.Number each spark plug wire using masking tape, if necessary, so that you know which wire belongs to which cylinder.Make sure the engine is cool to the touch.
