Brought to you by 1AAuto.com- your source for quality replacement parts and the best service on the internet. Hi, I'm Mike Green. I'm one of the owners of 1A Auto. I want to help you save time and money repairing or maintaining your vehicle. I'm going to use my 20-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 '04 Ford Ranger with a 4.0L. This coil does fit many Ford V6s from 3.0L up through 4.2L V6s. The only tool you'll need for this truck is a 7 mm and 8 mm socket and ratchet.
Coil on this is a 4.0L in a Ranger; this coil is the same for anything from a 3L to a 4.2L V6. To change the coil, the first thing I've done you can see I've marked these plug wires. I've just marked them basically one, two, three, four, five, six, closest to me then going around in clockwise order. For those of you that know engines, it has nothing to do with the firing order or what number plug these go to. It's just so that when I put them back on the coil, I'll put them on in the right order. If you're planning on changing plug wires, I suggest you replace the coil first and put the plug wires back on, and then just replace the plug wires one at a time.
For this video, we're just doing the coil. I'm going to remove all these wires. It's just a matter of squeezing the kind of lock here, and pulling up and off. These wires from over there, out of the way and these wires over here. Now your connection is right back here. Pull up on here and pull that connector right off. The coil is held on with four well, two bolts and two nuts. These are 7 mm bolts here and 8 mm nuts on the back, and I'll remove those.
Once those four bolts are out, coil comes right up and off. Here's our old coil. Here's our new coil from 1A Auto. You can see everything's the same. It's going to bolt up all the same. You can screw it right down on there. There's a little resistor or capacitor or something here that goes on with the bolt, so make sure you get that correct.
Check these and make sure they're as tight as I want them. Put our connection back in, then our wires. I guess I've got number three here. Again, the marks I have on these wires have nothing to do with the cylinder number. They only pertain to the closest one to me, one, two, three, four, five, six and then around clockwise. Four, five, and six. Now we can start it up and everything should be nice and smooth.

In this video we're going to show you how to remove and then reinstall an ignition coil in this 1998 Explorer with a 4.0 liter V6 with the EFI. This is basically the same as quite a few trucks with that motor in it. The only tools you'll need are an 8 mm wrench or socket and ratchet and a flat-blade screwdriver.
Disconnect the negative battery cable with an 8 mm or 5/16 wrench. Okay, so on this motor the ignition coil is right here, right on top, really easy to get to. If I'm just replacing the coil what I like to do, and actually even if I'm replacing the coil and the wires you want to do one at a time. You don't want to just pull all the wires off and pull them all off the plugs and then it will be kind of a mystery of how to get them back on. What I like to do is I just number them front to back. I don't worry about which cylinder on the engine they are technically, but I just make a mark. There's one and I make two marks on that one and then I know the one without a mark is the third one. Same thing on the other side. One mark on the first one and two marks on the second one. Okay.
Now I can pull my plug bars off by squeezing on here and then twisting and then off. Okay and then you've got your harness connection here. Use a screwdriver pull up. You'll have to pull pretty hard and it comes right off. Then four 8-mm bolts. Okay, this first one over here has kind of a harness connection. So you want to make sure that when you put it back together you put that back on where you just remove those four bolts. Two bolts are in the back kind of blind but they're just right at the corner. Okay and once those bolts are off the coil comes right up and out.
Okay, so here's your original coil, new coil from 1A Auto. You can see the 1A Auto coil is exactly the same. It's going to go in there and it's going to connect up the same. Now on this vehicle since it's kind of a demonstration vehicle and this coil is actually working fine I'm just going to reinstall the original one. Reinstallation, pretty straightforward. I'm going to lift those up and out of the way. Okay. Just make sure everything is pretty clean right there. Coil goes right down into place. Get one of the bolts started and then I'll get them all started and then tighten them up.
Okay then you remember, on this one over here you've got this bracket that you want to put on. Okay, and when you tighten these you want them firm, but they don't have to be incredibly tight. Okay, and now we've marked our wires here so there's my two. There's my nothing, so here's my one. So, that was closest to the front. Push it on. Two is the second one, and no mark is the third. Okay, we'll actually plug in the power connection there. No mark on that one; that's probably three. Grab our two over here. One mark and two and we're all set.
