Changing the spark plugs on a 1997 Ford Expedition 5.4L engine takes patience. Remember to start this project on a cold engine! I started on the passenger side by locating the Coil over iginition coils and cleaned out all the old dirt using some compressed air. Then I had to disconnect the electrical connections to both the Coil over ignition coils and the passenger side fuel injectors. Once you remove the small bolt which holds the ignition coil in place, use your compressed air again to blow out the spark plug hole. After that, you will need a 5/8" swivel spark plug socket and various length extensions to remove the spark plugs. Take your time because there is not much room for your hands. Before installing the new plug, check the gap and use clean engine oil on the new threads. Tighten the new spark plug and reinstall the coil over ignition coil. Reconnect the electrical connection to both the ignition coil and the fuel injector. Continue these steps with all eight spark plugs. You will find the ones on the drivers side are difficult because of the fuel rail gets in your way. Have patience and use swivel extensions to work around the tight spaces. When you are done, you will have saved lots of money! Don't forget to replace your air filter, fuel filter, and pcv valve to complete your tune up.

That's because they are hidden quite well. If you look at the engine, you'll see yellow plastic prongs (?) that look like spark plugs, but hook up to the silver tubing.  That's the fuel injectors.  BUT, right behind the yellow plugs, are black ones.  The black one is the connector to the spark plug.  The plug itself sits about 4 inches down into the block of the engine.  They are a real pain, and from what I can tell, you only have decent access to the first 2-4 of them, then they get too far back and start going under the dash (you'll see what I mean when you get there).

A set of spark plugs usually requires replacement after about 20,000–30,000 miles (32,000–48,000 km), depending on your style of driving. In normal operation plug gap increases about 0.001 in. (0.025mm) for every 2500 miles (4000 km). As the gap increases, the plug's voltage requirement also increases. It requires a greater voltage to jump the wider gap and about two to three times as much voltage to fire the plug at high speeds than at idle. The improved air/fuel ratio control of modern fuel injection, combined with the higher voltage output of modern ignition systems, will often allow an engine to run significantly longer on a set of standard spark plugs, but keep in mind that efficiency will drop as the gap widens (along with fuel economy and power). When you're removing spark plugs, work on one at a time. Don't start by removing the plug wires all at once, because, unless you number them, they may become mixed up. Take a minute before you begin and number the wires with tape.

  1. Disconnect the negative battery cable.
  2. If the vehicle has been run recently, allow the engine to thoroughly cool.
  3. Remove the spark plug cover(s), if equipped.
  4. On the 2.5L engine remove the ignition coil assembly from the rear valve cover. See Section 2 for the procedure. Remove the water pump pulley cover.
  5. Carefully twist the spark plug wire boot to loosen it, then pull upward and remove the boot from the plug. Be sure to pull on the boot and not on the wire, otherwise the connector located inside the boot may become separated.
  6. Using compressed air, blow any water or debris from the spark plug well to assure that no harmful contaminants are allowed to enter the combustion chamber when the spark plug is removed. If compressed air is not available, use a vacuum to clean the area. NOTE: Remove the spark plugs when the engine is cold, if possible, to prevent damage to the threads. If removal of the plugs is difficult, apply a few drops of penetrating oil or silicone spray to the area around the base of the plug, and allow it a few minutes to work.
  7. Using a spark plug socket that is equipped with a rubber insert to properly hold the plug, turn the spark plug counterclockwise to loosen and remove the spark plug from the bore. WARNING
    Be sure not to use a flexible extension on the socket. Use of a flexible extension may allow a shear force to be applied to the plug. A shear force could break the plug off in the cylinder head, leading to costly and frustrating repairs.
  8. Remove each plug and inspect the plug even if you are replacing them with new ones. An inspection can reveal a great deal of information on the overall condition of an engine. Use the condition charts in this section as a guide. To install:
  9. Inspect the spark plug boot for tears or damage. If a damaged boot is found, the spark plug wire must be replaced.
  10. Using a wire feeler gauge, check and adjust the spark plug gap. When using a gauge, the proper size should pass between the electrodes with a slight drag. The next larger size should not be able to pass while the next smaller size should pass freely.
  11. Carefully thread the plug into the bore by hand. A handy tool to use to install spark plugs are the flexible rubber installation tools that are available at most auto parts stores, in place of this tool an old plug wire boot or a piece of fuel line long enough to fit to the plug hole is a good alternative. If resistance is felt before the plug is almost completely threaded, back the plug out and begin threading again.
  12. Carefully tighten the spark plug. If the plug you are installing is equipped with a crush washer, seat the plug, then tighten about 1⁄4 turn to crush the washer. If you are installing a tapered seat plug, tighten the plug to specifications provided by the vehicle or plug manufacturer.
  13. Apply a small amount of silicone dielectric compound to the end of the spark plug lead or inside the spark plug boot to prevent sticking, then install the boot to the spark plug and push until it clicks into place. The click may be felt or heard, then gently pull back on the boot to assure proper contact.
  14. On the 2.5L engine, install the coil pack and the water pump pulley.
  15. Install the spark plug cover(s), if removed.
  16. Connect the negative battery cable.

These plugs can be difficult, the plug design sucks and if you are not careful you can break them off in the head. Ford issued a TSB069-2008-1 on how to properly remove the plugs and also there is a special tool so if you break a plug off. My friends cost him 300 for a dealer to do it and saved a lot of time. Hope this helps you out.....

SOURCE: how to change spark plugs on a ford expedition

I recently changed them and it was a job when you have to crawl up and inside the engine area. But anyways, I started out by buying the E3 plugs, which don't have to be gapped and they do save a little gas plus increased in a little more power. (not much), These set me back $56. go with a basic motorcraft platinum or bosch platinum. I then removed the top engine cover, removed bolts for fuel rail and easily pulled the injector rail up (you will see to replace the o-rings on the injectors by some people, but if you're careful you don't have to.) This gives you the room you need at the back of the engine to remove the plugs. I started at the front by removing the small bolt holding the coil in place, then removing the the coil/wire with a boot removal tool. ( Again you don't need this tool, but it comes in handy at the back plugs). After removing the coil, I simply remove the plug, Apply anti-seize to the new one and install plug. I then apply Di-Electric grease to the inside of the coil boot to prevent moisture getting in. I then install the coil back down on the plug and tighten down and move on to the next.
1. you will need a swivel for the socket
2. you will need an extension, ( I use a long 8" extension)
3. Anti-Seize Grease
4. Di-Electric Grease
5. If installing a plug to be gapped it is .54
6. After installing, check for fuel leaks at the injectors.

It took me about 1 1/2 hours to replace all plugs and a dealer charges about $375. Good Luck if you need any further help get back to me and I'll help any I can.

How to change spark plugs in a 2000 Ford Expedition


This is one of the longest repairs I have ever done on just changing spark plugs! A dealership will charge you $200 and up for this job. They take between 2-4 hours labor!

Here is a great guide in AutumnsList forums with great detail to help everyone out. It also has a lot of great tips so you do it right.

I believe it is the same for earlier and later models too. Maybe from 1998 to 2003 models.

HOW TO CHANGE COIL PACK ON 2000 FORD EXPEDITION EB 5.4 ENGINE?


Ther is no coil "PACK" on your engine. Each plug has its own coil. Each one is held in place by a single 8mm head bolt that screws into the intake plenum. To change them you simply disconnect the electrical connector, remove the bolt and pull the coil and spark plug boot up out of the spark plug tube. (Reverse proceedure to install.)

Plugs are near the top of the cylinder heads facing upwards. They are not fun to change as the passenger's side doesn't have a lot of room to work in.

It does not take 3 hours to change spark plugs..I will suggest you get the right equipment to do this job.Get the right tool that can sit on the spark plug and unscrew....You will need to disconnect the coil pack that sits on top and disconnect the wires if needed.From there it is self explanatory.
