Hi, I'm Mike Green, I'm one of the owners of 1AAuto. I want to help you save time and money repairing and maintaining your vehicle. I'm going to use my twenty plus years' experience restoring and repairing cars and trucks like this to show you the correct way to install parts from 1aauto.com The right parts installed correctly, that's going to save you time and money. Thank you and enjoy the video.
In this video, we're going to replace the ignition coil on this '97 Expedition or one of the ignition coils. These coils, Ford used on many cars and trucks with either the 4 cylinder they either used one coil for 4 cylinder, or V8 they use two coils. This thing can fit anything from a 2.0 liter 4 cylinder to a 5.4 liter V8. The only tool you'll need is a ratchet and a socket with extension, a 7mm socket. Only the location of the coils is going to vary depending on what vehicle you have.
To replace this driver side coil, first you need to kind of get your air box and just kind of bring it up and move it out of the way. Now that we got the air box out of the way there's four 7mm bolts here. One here, here, down here, and then back there you can't really see. You can see probably the top of my can of penetrant. I'm going to do the best I can to use this little red tube to spray some penetrant on all the bolts under here and that will make them a little easier to come out.
Ok, so I've run into little bit of a problem here. You can see that these two bolts came out and actually my third bolt over here that you can't see is out. This bolt here, the head was so rusty it actually stripped, so what I'm going to do I'm going to take a marker and I'm going to start with the one closest to me. Mark that as one, two, three. Make sure we got two marks there, one, two three, and the one without marks is the fourth one. That way I know the number one stared closest to me and then clockwise around. Now I can unhook these. Now what I'm going to do, I'm actually just going to take my coil, and unfortunately on a rusty bolt in a truck like this, it's kind of the only way. What I did is I just broke that bolt. I'll be able to put my coil back on with three bolts and, not ideal, but it will hold it just fine. Hope that when you're doing your truck, it will all come apart easy. But if not, if you lose one bolt, it'll be ok.
Ok so I'm ready to bolt in my new one, I've got a little bit of a problem here. This one bolts on, on top here where our broken bolt went so I can't quite get it there so what I'm actually going to do is I'm going to put this clip on right here and then I'm going to put the coil on top of it so it's pinched down in there, then I'll start my bolts. I'll get these going and I'll tighten them up and we'll be all set. Plug this in and then these will kind of settle down right where they were anyways. There's my number one mark very close to me. That's got three marks on it, two marks. Last but not least, this guy has no marks. Now we can start her up and make sure everything's running good. Put the air box back here. Everything sounds good!

Your passenger side ignition coil is right here on the front of the engine, on the passenger side. The best way to do this is to start by holding your new ignition coil in its place and pulling the wires off one at a time, so that you don't get them mixed up. All right, there's one. There's two. There's three, and the last one. Make sure they're fully snapped on. With those on the coil, you can set it aside.
Now you're going to want to remove the plastic electrical connector from the side of it. You can do that with your flat tip screwdriver. If you slide it in the upper and lower tabs, it allows you to pull the connector off, just like that. The ignition coil has four bolts holding it to the engine itself. They're seven millimeters. There's two on the top, and then on the bottom. You can't see them, but they're on the opposite corners. We're going to start with the bottom ones, because they're the most difficult. Use your 7mm socket with an extension. With all four bolts loose, you should be able to hopefully just pop this off from the bracket. Nope, one of them's not quite there. There we go. On the bottom front corner, there's actually another little device hanging off the screw, so you have to pull the screw completely out.
At this point, you can take your new coil, and put the screws into the new coil. Remember the bottom front one is a special one. We'll put it right in place, and then start off by hand tightening all of the screws, because you don't want to cross-thread them. That'll make for a very bad day. Now you can use your 7mm ratchet to get on the bolts. I like to start with the bottom, because I do all the most difficult stuff first. The last part of the process is to snap the connector back onto the coil, just like that.

We're going to unscrew the clamp that's holding the air filter box in place, and once it's nice and loose like so, you can lift straight up on the air filter box and it will pop right out. You can see on the bottom it has these two posts that it sits in, and they slide right into these rubber grommets in the body itself. You can just set that aside and get it out of your way wherever it happens to fit. Right there looks like a perfect spot.
You don't want to mix up your coil wires, so what we're going to do is we're going to have the new coil just held here in place, and we'll pull the coil wires off one by one and snap them onto the new coil. That way you don't get them mixed up. Once that's done you can set the coil aside and we'll pull the old coil off.
To disconnect this connector you'll want to take a flat tipped screwdriver and kind of pry it in the upper tab and lean it back, and then you can do the same thing to the bottom and you can see it pops off just like that.
With the connector out of the way you'll use your 7 millimeter socket with an extension to reach the four bolts that hold the coil to the engine. With all four screws loose you should be able to pop it off the engine.
Then this one has the extra little device on here that you'll need to undo to get the coil out of the way.
Now you can pull your new coil right into place. Put this bottom screw in first, then you can do the other four as well and start threading them in by hand. With all four screws loosely started by hand, then you can go in with your 7 millimeter ratchet and extension and socket, and tighten them up.
Now we'll connect the connector on the side of the coil. All you have to do for that is push it right in and it will snap right into place.
Now you can take your air filter box and put it right back into place. Slide it in this end first, and then on the bottom you've got these two pins that you can push down into the body. Once it's connected at the body you can use your flat tipped screwdriver to tighten the hose clamp.

Purchased an old 1998 Ford F150 that had been setting for four years for $600. Wouldn't run. We replaced the fuel pump and got it running. Had a miss so upon further investigation, we found one of the coil packs cracked and that was the one we were getting the misfire from. Received them as promised and installed that evening. Took just a few minutes to install and truck runs great. Great fit and easy install. Thanks Again.
P.S. Everything I have bought from 1AAuto has been quality and perfect fit. I have no complaints on any items I have bought and plan on buying more items from 1AAuto in the future. I recommend them to everyone.
Great job

Vehicle: 1996 Ford Explorer, Eddie Bauer Edition, 5.0 V-8
My vehicle began to run rough and the PCM threw a "P0307" code, "a misfire has been detected in cylinder 7." I decided to replace the coil packs, spark plugs and wires. 1A Auto did not have the plug wires I needed but they did have the coil packs. I ordered these and they arrived in just a few days. They were a perfect fit and installed easily (the plugs were a different story). When all was said and done the vehicle is running great and the code has not reappeared. As with other purchases I have made from 1A Auto, I found the parts as described, priced competitively and quickly received.
Great product
