How do you change plugs on a 2000 F250?

Answer 1

This is not easy at all due to very poor engineering design by Ford! This can be done but will take several hours, expect to spend a weekend day to change all eight plugs, be patient and take breaks...Be sure to use 'Autolite double platinum electrode' or better plugs as you will not want to do this often! It is worth the money here to put in the best plugs available! After removing all of the stuff that's in the way which is practically everything on top of the engine, use electrical tape to tape the spark plug to a 5/8in deep socket, not a spark plug type of socket ( you will never get a 5/8in spark plug socket out of that deep rusty hole without removing the plug again because the foam inside the sparkplug socket in combination with the rust in the hole will grip the socket more than the extension does to the socket resulting in a stuck socket), use one long extension. Upon reinstallation, use electrical tape to tape the coil mount screw to a socket. Be careful not to drop any screws, you will not have fun trying to find them, there are no spares and they are all needed! The coil connector plastic lock clip breaks off very easily too! Do not try to install without the lock clip, the connector will fall off! Run a couple of black UV resistant plastic tie wraps together and then between the two input wires of each coil connector and attach against something solid such as the fuel rail mounting brackets. Take your time, be patient and Good luck, your truck will soon be good for another 100,000 miles!

Answer 2

It is important to replace car parts after so many miles. Spark plugs are changed by disconnecting the batteries, the spark plug cables, removing the spark plugs, replace them with new spark plugs, reconnecting the cables, and the car battery.

How to Change Spark Plugs on 4.6 & 5.4 Liter By Dave West I've replaced plugs on quite a few 5.4Ls now (the 4.6L with plug wires is similar) and once you've done a set they really are not as bad as they look. Contrary to what some people will say, you don't have to remove the fuel rails. The Coil on Plug (COP) assemblies will come out past the fuel rail. I take an old piece of seat foam and put it on top of the radiator support to the engine to allow me to lay on it without hurting my tummy. It makes the job way less painful. Start by removing the cover over the throttle body (the black plastic cover that says "5.4" on it). There are three 10mm head bolts that hold it on. Next remove the air intake tube from the throttle body to the air filter housing. You loosen the hose clamps at either end of it; disconnect the connector on the AT (about half way up the air intake hose), the pull out the small hoses that go into the air intake tube near the throttle body. Next remove the brace from the Power Steering reservoir to thermostat housing. There are three 8mm or 5/16" head screws that hold it on. Now you should be able to see the COPs. To remove the COPs you can use a 7mm or 9/32" wrench or nut driver or socket, extension and ratchet or all of the above. If you turn the fuel injectors to the side it will give you more room to work with the COPs. Unplug the connector on each COP by pressing the tab in and pulling on the connector. After you're done that just twist and pull the COPs out. A couple of the COPs on the driver's side and #4 on the passenger's side are a bit hard to get at but with some patience they will come out. After you've removed the COPs take a blow gun and blow out the spark plug holes. Don't be surprised if there is rust and junk in them. Next you can actually remove the plugs. Use a combination of extensions, swivels (universal joints), sockets and ratchets to get at them. Whatever works best for you is good. On the harder ones to get at I usually use a socket with a 4" extension, then a swivel, then a long extension, then the ratchet. The plugs are way down in the hole which is why I use the extension then the swivel. The swivel makes it easier to clear the firewall. Set the gap on the new plugs to whatever it says on your emissions decal on the radiator support....usually .052-.056". Apply a small amount of anti-seize to the threads only on the spark plug. You can use a piece of vacuum hose or fuel hose over the end of the plug to get it started in the hole. Carefully start the plugs in their holes. If you can't get them most of the way in by hand with the hose take a look and see why not. Cross threaded plug threads are no fun! The plugs are to be tightened to 13 lb-ft. which is just hand tight with a short ratchet. Don't over tighten them! The threads in the aluminum heads have enough problems as it is. After that just put everything back together in reverse order. Apply some dielectric grease to the plug boots as well to help seal them. I've done enough of these that I can replace the plugs in approximately 45 minutes but don't be surprised if the first time you do it takes a few hours.

Answer 4

Assuming this is asking about the spark plugs on a 5.4... It's fairly simple but just takes time.

There are two ways to do it, with a ratchet, spark plug socket (7/8ths) ratchet with a long extension between the ratchet and U-joint and a short extension for the plugs and a 7 MM socket to get the coil pack off, mind you if you do it this way you need a 7 MM, long wrench to get cyl. # 5 and # 7 which are.... close to impossible to change this way but with a lot of finagling it can be done. It takes about 4 hours to do it this way...

The other way, less practical but way easier way, is to pull the fuel rail off the truck. To do this you need to disconnect the battery, then us a fuel pressure gauge with a bleed-off valve to depressurize the fuel system. You also need a special tool to get the lines off the back of the fuel rail to pull it off the motor, or if you are brave enough to just lift the fuel rail away from the cylinder you are working on you can do that too. then once the rail is out of the way, just unbolt the coil packs and change the spark plugs.

Both ways require you to pull the air intake and really that's it, Just remember to use dialect grease on the threads and wire end of the plug, and to not over tighten them because it is going into an aluminum head which can stripeasily

Answer 5

undo the console on top of the spark plugs and they are 2 each 2 plugs they are 16 spark plugs in total
