If your can see the difference between .020 (20 thousands) and .025 (25 thousandths) of an inch than you may not need a gap tool.
A $3 spark plug gap tool is a must, you can get it at any auto parts store. Also if your spark plug is stuck in the socket, get a new socket and spark plug, but if you need it now take the socket wrench off the socket and place the socket in a vice. Then with the biggest screwdriver that will fit in the socket wrench hole, place the screw driver tip on the top of the spark plug stuck in the socket and hit the other end of the screw driver with a hammer until the spark plug comes out...... get a bigger hammer. note: the old spark plug may not survive.
The OE Autolite plugs installed in the Navigator use a 9/16 inch socket, which is most exactly the same diameter as the thread area, which makes it look round in the hole. The Champion 7989 uses a 5/8 Spark Plug Socket, which is one of two "standard" plug sizes. The other "standard" plug size is 3/4 inch, which is not used very widely any more.
You need a special socket called a Plug Socket. It is longer, and allows the socket to fit over the Plug. They aare readily available, and you should be able to get one at your local hardware or tool shop.
You will have to remove the intake assembly to be able to remove the spark plug. You can also go about it from the ignition coil. To replace the spark plug, please follow the steps below to do so. You will be needing these instruments: Phillips screwdriver, Socket wrench, Spark plug socket, Anti-seize compound, Dielectric compound, Small screwdriver, then follow the steps:
Disconnect the car's negative battery cable at a time when the engine is cool.
Unscrew the individual ignition coil using a screwdriver and then remove the coil and set it aside.
Pull out the spark plug wire at the plug end, grasping it by the boot and twisting it out; a special tool for this is available. Disconnect the same wire at the ignition coil.
Clean out the spark plug's hole, using compressed air to blow out all dust, dirt and debris from inside.
Remove the spark plug from the engine using a socket wrench with a spark plug socket; turn the plug counterclockwise to remove it.
Apply a thin coat of anti-seize compound to the threads of the replacement spark plug. Make sure you get no compound on the plug's electrodes.
Thread the spark plug into its hole, making sure you don't cross-thread it, and then tighten it with the wrench and spark plug socket.
Coat the insides of the spark plug boots with dielectric compound; use a small screwdriver to apply the compound.
Install the ignition coil and screw it into place.
Repeat the above steps for each spark plug/wire that needs changing and installation.
Reconnect the negative battery cable once you've installed all necessary plus and wires
they make special sockets sometimes for certain model vehicles they are very thin and allow access to the plug ..most other style plug sockets are thick and this will occur .some parts store's will allow you to borrow the tool you need to extract the plugs a deposit may at some be required but is returned when the tool is returned .good luck !
that rubber ring is the bottom of the spark plug wire boot you will have to get this out before you can get the plug out. no special tools needed except socket long extension and ratchet. just remove the wires or coil over ignition coils however your car is setup, install socket and remove the old plug.
no special tools,this is what tools you will need:.7mm socket for the coil packs where underneath them is a deep hole and down there is the plugs---8mm socket for the fuel rail bolts(for the left side sitting in it)which i would use 1/4 inch drive for these--- 5/8 plug socket---6 inch extension---3 inch extension---ratchet---swivel---which i would use 3/8 inch drive for these---and maybe long needle-nose pliers incase the rubber boot from the coil packs come off and sticks to the plug.
