Easy Way to unscrew spark Plugs and wires on any car

3.7L Engines
Each individual spark plug is located under each ignition coil. Each individual ignition coil must be removed to gain access to each spark plug. Refer to Ignition Coil Removal/Installation. Prior to removing spark plug, spray compressed air around base of ignition coil at cylinder head. This will help prevent foreign material from entering combustion chamber.

1. Remove spark plug from cylinder head using a quality socket with a rubber or foam insert.
2. Inspect spark plug condition.

To install:

1. Start the spark plug into the cylinder head by hand to avoid cross threading.
2. Before installing coil(s), check condition of coil o-ring and replace as necessary. To aid in coil installation, apply silicone to coil o-ring.
3. Tighten spark plugs to 27 Nm (20 ft. lbs.) torque.
4. Install ignition coil(s). Refer to Ignition Coil Removal/Installation.

1. Remove necessary air filter tubing at throttle body.
2. Prior to removing ignition coil, spray compressed air around coil base at cylinder head.
3. Prior to removing spark plug, spray compressed air into cylinder head opening. This will help prevent foreign material from entering combustion chamber.
4. Remove spark plug from cylinder head using a quality socket with a rubber or foam insert. Also check condition of ignition coil O-ring and replace as necessary.
5. Inspect spark plug condition

Hello, first how many miles do you have on this Lincoln? On that 4.6 L V8 engine they do have spark plugs but each plug has it's own spark coil located on a long rubber plug. You will see four little coils on each side of the engine. There will wires going in to the individual coils. There will be a bracket the holds the coils in place with a small 9 or 10 mm nut. Remove the nut, and gently pull on eac coil. There Hello, first how many miles do you have on this Lincoln? If you have over 120 thousand miles on this engine then it might need new spark plugs. On that 4.6 L V8 engine they do have spark plugs but each plug has it's own spark plug coil. You will see four little coils on each side of the engine. There will wires going in to the individual coils. There will be a bracket the holds the coils in place with a small 9 or 10 mm nut. Remove the nut, and gently pull on each coil. There a long rubber plug that fit in each spark hole. These rubber plugs are about 4 1/2 to 5 inches long.


Before removing the plug use an air hose with 50 to 60 lbs of pressure to blow each spark plug hole out which might have foreign object in the hole. Why, if you remove the spark plugs, and there is foreign material in that plug hole. Guess what, that stuff will fall into the combustion camber.



Then you will really have some problem. How fix if stuff fall into the combustion camber.

Squirt small amount of oil in the combustion camber, unplug all the coils and clear out there plug hole. Now remove all the spark plugs. Now, you can crank the engine and will the little amount in that cylinder that has the junk in it. The oil will wet the foreign debrie, and blow it out the spark plug hole. Then use a clean rag with with some oil it with a long screw driver to clean that spark plug hole Be careful that don't push the foreign material back into the combustion camber. Do this several time with little amount of oil.



Now, you can install the new spark plugs. On the spark plugs threads use some anti-shiz grease. Why squirt oil into the combustion camber? The oil is used to seal the rings on the piston to increase the cylinder compression. Just a small amount goes a long ways. GB...stewbison

First, I would highly recommend that you also purchase a set of igniton cables and replace these also because you are most likely to have damaged spark plug boots when you remove the boots from the plugs. Trust me...it happens about 95% of the time, and you will be way ahead of the frustration if you are prepaired.

Pull the spark plug boots off of the spark plugs.

NOTE:

Allow the engine to cool before removing the spark plugs. Attempting to remove the spark plugs from a hot engine may cause the plug threads to seize, causing damage to cylinder head threads.

Clean the spark plug recess area before removing the spark plug. (spray brake cleaner and compressed air works well) Failure to do so could result in severe engine damage because of dirt or foreign material entering the cylinder head, or by the contamination of the cylinder head threads. The contaminated threads may prevent the proper seating of the new plug. Use a thread chaser to clean the threads of any contamination.

Screw the spark plugs out of the cylinder head.
Check the air gap at the electrode end of the spark plug.

The specification for the plug gap on your vehicle is 1.524mm (0.060 in)

Place a SMALL amount of nickle-based antiseize compound on the spark plug thread, being very careful not to get any on the porcelain portin of the plug. If you do get antiseize on the porcelain part of the plug, it is imperative that you clean it off thouroughly using brake cleaner and a clean rag, otherwise it could cause cylinder misfires.

Screw the spark plug into the cylinder head and torque to specifications.
The spark plug torque specification for your vehicle is 15 Nm (11 ft. lbs.)

NOTE: Failure to properly torque the plugs can cause severe engine damage. Overtightening the plug can damage the threads in the cylinder head and/or make spark plug removal in the future impossible. This will cause you to have to remove the cylinder head for repair the next time the vehicle needs service on the spark plugs.
Undertightening can cause the plug to leak compression and damage the threads in the cylinder head. This can result in the plug blowing completely out of the head causing severe cylinder head damage.

When replacing the ignition cables, make sure they are routed EXACTLY as they were originally routed from the factory. Make sure that all protective wire loom and fasteners are transfered to the new wires and secured properly. Failure to do so can cause damage to the cables, engine misfires and can cause the spark plug wires to "spike" sensitive sensor circuits that are nearby and cause damage to the sensors or your computer modules. Improperly routed ignition cables have also been known to cause interference in radio and stereo systems.

HINT: The rear plugs on your engine are much easier to get to if you remove the two engine struts that go between the engine and the upper radiator support. You can then use a ratchet strap to pull the engine forward to get more room to work on the rear plugs.

the oil was the cause of the misfire, the oil swells the rubber on the plug boots and interferes with the electrical connection from the wire to the plug. when you replace the gasket, remover the plug wires, marking which one went where, and use a spray electrical cleaner to remove the oil. make sure the rubber on the new wires isn't already swelled. before removing the plugs or valve cover, spray brake cleaner down in the holes and use compressed air or shop rags to get the hole shiny clean before removing plugs. remove plugs and clean them too. then reinstall plugs and remove valve cover. when replacing any gasket, use a razor blade on to clean the surfaces well. you can even spray a shop rag with brake clean and wipe it to make sure its clean. clean is important. reinstall cover with new gasket in place and torque bolts... be careful not to overdo it, they are small bolts and overtightening can flatten out gasket and cause more leaks. then just reinstall plug wires and off you go
