Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and the next time you need a part for your vehicle, think of 1AAuto.com. Thanks.

In this video we're going to replace the ignition coils. We're going to do one of the coils; the second coil is basically the same procedure. All you're going to need is a 7/32 socket with a ratchet, and maybe an extension.

The coils are on the side of the engine. The original ones are marked one and four on that front one. Then you see there are the One Cylinder, Two Cylinder, Three Cylinder, and Four Cylinder. You follow that Four Cylinder wire right to the coil, and it's hooked to the four post. It's very important when you replace your coils, obviously, that you plug the spark plug wires back in correctly.

We do two things. We only replace one coil at a time, and as we take the coil off, we put the wires onto the new coil. The other thing you can do as well is you can just mark the new coil with a paint marker with the same markings as the original. As you saw before, the cylinders are one, two, three, and four from left to right. Make sure you plug them in correctly to the new coils.

The coils are held in by two bolts. You can see one right at top, and then the other one from the other coil if you unplug that lead there. There's the other one, and then there's the bottom screws that are directly opposite of the top ones. You can see here, Don goes for the bottom bolt first, and that's a 7/32 socket with a ratchet. You will need a socket and ratchet to do this. It really is pretty much impossible to get to the bottom bolts with a wrench. So he removes that bottom bolt first, and then he'll turn his attention to the top bolt. Now, with the bolts undone, take the coil out, and then Don removes the two bolts from the coil. Put those aside.

Here's the new coil from 1A Auto, it's exactly the same as the old one. Now, what Don will do, is he'll take and remove one of the plug wires, and just plug it right into the new coil. Then he'll take the other plug wire, unplug it from the old one, and plug it right into the new coil. That way he doesn't have to worry about remembering which one goes where. There are two tabs on the coil base. They line up in the coil. Just be careful that you don't bend those tabs. Get the new coil in place and plugged in. Then reinstall the bolts.

Hi, I'm Mike Green. I'm one of the owners of 1AAuto. I'm going to help you save time and money repairing and maintaining your vehicle. I'm going to use my 20+ 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'll be showing you how to replace the ignition coil on this 1997 Pontiac Sunfire with a 2.2 liter in it. This is basically the same as any 2.2 liter or 2.4 liter 1995 to '05 Cavalier or Sunfire. The only tools you'll need are a 6 mm socket and ratchet with an extension.

In this video, I do it from underneath the vehicle. That's how I recommend it. I have been told that you can do it from above, but you can't really see anything and it's pretty difficult. If you do it my way, you'll need a jack and jack stands to raise and support your vehicle.

To replace an ignition coil, it's actually best to go up underneath the car. You can see, here's the axle and this is the coil. It's hard to get my arm up in there to point it out. The coil is right there. First, mark the plug wires. To mark these wires, I'm just going to use the Roman numeral method. On the top one, I'm just going to put one mark, on the second one I'm going to put two marks, third one I'm going to put three marks, and the fourth one I'm just going to leave unmarked. Number one has got one mark, the second one down here has two marks, third one has three marks and the fourth one is unmarked.

Now I can remove those plug wires. You want to reach up above them, get your hands on them, and pull them off. Obviously, if you're replacing one coil, you might as well replace them both since you're underneath here. If one has gone bad, then the other one is probably not far behind it. If you can, it's good to give these wires just a little bit of a twist and you might find that the boots pull off a little easier.

Looking up in here, you can see that there is one bolt and then up above is the other bolt. The other bolts are basically right diagonally across. There's no good way to film them. That one bolt that we can see here and then the other bolt goes in right here. You want to take those two bolts, per coil out and they're either 6 mm or actually 7/32's work if you have standard-sized tools. Obviously you want to be working up here when the engine is cold because you're working next to your exhaust pipe.

There's one bolt out. There's the other bolt. You're going to reach up in here and pull it straight out and then down. You can see on there, there is a one and a four. The top one is cylinder number one, and the bottom one is cylinder number four. If you do have a code, and you're getting a code of a misfire on one and four, you know it's the bottom coil you've got to replace. If you're getting a misfire of two or three, it's the top one. Again, if you're getting a misfire on one, you might as well replace them both because, like I said, if one is failing, the other one's probably not far behind.

Here's our original coil. Here's the coil from 1A Auto. Everything is the same. It's going to bolt up all the same. Obviously, they're going to have the one or the four because it's intended to replace either one. If you wanted to, you could just use a little bit of paint or something and paint the one and the four on there, so you knew which one, but like I did before, is I just marked the plug wires from top to bottom as they came down. I didn't necessarily mark them with which cylinder they pertain to.

The 1A Auto one is going to bolt in. It's going to work great, no problem. You can see where I took the coil from. There's two prongs. Those prongs go into the coil right there, so when you put them back up in there, you want to be careful to not bend those prongs or anything. I'm going to put it back up in there. I'm going to go straight at the prongs lightly dance back and forth here until I feel the right spot and then push on. Grab a bolt and put the bolt in and start it, feed it in there. Another bolt, put it up in my wrench, and go up in between, feel for the hole and get it started. These need to be tight, but not incredibly tight.

Here's my wires. Find the one with the single mark on it. That one's got two marks, that one's got one mark, I'm going to put it up top. This one's got two marks on it, we'll put it on the second one from the top. That one has no marks,that one's got three marks and that has no marks: number four, the fourth from the bottom. There you go.

In this video we're going to show you ignition coil replacement. This is an '03 Monte Carlo SS with a 3800 or 3.8 liter. The same engine that's in a ton of different vehicles from the late 90's to the late 2009, 2010 era. The same procedure for all vehicles. The only tool you're going to need is a socket and ratchet with an extension, either 6 mm or a 7/32.

Coil replacement, this is a 2003 Monte Carlo SS. It has got a 3800 V6, pretty typical of a lot of GM cars, great little engine, good power, lasts a long time. The coils for the most part are right on the side of the engine, right here. You can see that there are three of them. Each coil handles two cylinders, so they're really nice and easy to get to on these V6's. This is pretty much the same as the 3.4 liter V6 as well. I'll show you how to replace these. Okay, replacement is really quite easy. You start by removing the plug wires and I do one coil at a time. You don't want to just unplug all these wires. You want to make sure you have to plug them back into the same spot.

I just unplug. I take that one and leave it right up there. I'll take this one that's lower and I'll put it down here. Now I have two bolts here that I have to remove. Okay, those two bolts are 6 mm and actually 7/32 and a standard socket works as well. Okay, then the coil comes right off. You can see that it plugs into two tabs right there. You want to be careful when you raise not to bend those tabs at all. Okay, this is our original coil. This is our coil from 1A Auto. You can see that they're the exact same. Obviously our coil doesn't have the numbers on it; because, it can be used on any of the three positions. Everything's the same. Everything is going to bolt in the same. It has the same plugs there. I am going to re-install the original coil; because, there's nothing wrong with it on this car. I just wanted to show you that.

A good practice when you're re-installing the coil is to put these bolts in, okay. That way when you put it down on you can see that the bolts go into the right place and that you have the coil lined up, okay, so then just kind of lightly work it down on there. Then push those bolts on. I'm going to tighten up with my air ratchet. Now I'm going to finish tightening it up by hand. Never want to use the ratchet to tighten something up; because, you want to know how tight it actually is. Okay, I know I left this top one up here. I'll put that one on and then this bottom one down here. I'm going to put that one on. Just repeat that for the other two.
