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.

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

In this video, we're going to show you how to remove and replace the engine ignition coils on this 2000 Buick LeSabre, same as a 2000 to 2005 LeSabre, and pretty much the same as a lot of vehicles that have the 3800 Series V6. The only tool you'll need is a 7/32"? socket with a ratchet and extension.

The ignition coils on the 3800 V6 in this Buick LeSabre is very conveniently located right here on top. When one of these starts going bad, usually what it does is it will turn the check engine light on and it will say something like misfire in cylinder number 6 or 5 or 4 or something. That's generally a good indicator that your coil is starting to go bad. If that is the case, they're pretty easy to replace. You can see that the original coils are marked here with their cylinder numbers. We know that this plug is cylinder number 3. This wire goes to cylinder number 6.What you first want to do is get these plugs kind of a twist, and then pull off. Give this wire a little bit of a twist and then pull it up and off. Then, there's two 7/32"? bolts. Remove those. We'll just speed it up here as we remove those two bolts. Once you have those off, just pull the coil straight off.

Here's the new coil from 1AAuto. Right here, there are a couple of tabs or those are actually electrical connections and they go in right there. You want to carefully equip this right now. What you can do actually is put your screw in. Make sure that goes in and then put the coil down carefully onto those tabs. It basically plugs right in just like that. Then put another screw right down in.

We'll speed things up again here as we just put those two bolts in and tighten them up. Again, tighten them nice and firm. You don't want to over tighten them, though. This was the top plug wire and then the bottom plug wire. Because the replacement coil can fit anyone of these positions, they don't come marked with the serial numbers but you could take a crayon or some type of white paint marker and mark your cylinder numbers back on there using the old ones if you wanted to.

A suggestion would be if one of your coils goes bad, obviously at 1AAuto, we sell the coils so you can buy all three. I would also replace your plug wires and your spark plugs. That's kind of a way you do a basic tuneup on these newer engines is replacing the coils, plug wires, and spark plugs.

In this video, we're going to show you how to replace an ignition coil on this 2003 Chevy Monte Carlo with the 3.4 liter V6 engine. The only items you'll need is a new ignition coil from 1AAuto.com, a 7/32 inch socket, and ratchet.

On these V6 engines, you have three ignition coils back here and you want to mark the wires with a separate marking on the two attached to the ignition coil. You're going to remove and then disconnect those two wires. These markings will just help remind you where they were, and then you want to remove this 7/32 and this 7/32 bolt.

Once you remove those bolts, you want to just lift it up carefully off of the prongs and then pull it free. On the left is the old ignition coil; on the right is the new one from 1A Auto. You can see they're identical, and they'll fit exactly the same. Take your new ignition coil, and we mark the numbers on it so I've matched our old one. You want to put those slots down onto those prongs right there, so carefully lower it down onto those prongs and then tighten up those bolts. Now, reconnect your spark plug wires, making sure you're putting them in the right spot, and then you're all set.

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.

In this video we're going to show you how to replace an ignition coil in a '97 Buick LeSabre. It's going to be the same operation for '97 through '99. You're going to need a 7/32"? inch socket and socket wrench and a new coil from 1A Auto.

The LeSabre has three ignition coils located on the top front of the engine. I'm using a 7/32"? socket and socket wrench to remove two screws that hold it in. As you remove the coil and take your spark plug wires off, just remember which one goes to the left post and which one goes to the right post.

Here you see the old part, and the new part from 1A Auto, which is identical, and will go in exactly the same way. Start by plugging in your wires. Seat it down, be careful not to bend these two connectors. Here I'm just re-installing those 7/32"? bolts. Just note that the procedure is the same for all three coils.

In this video we're going to show you how to replace the ignition coil on this 98' Venture with the 3.4 liter, same as probably the Montana and the Silhouette. These coils are used on a lot of different GM engines. The way we do it on this van may not necessarily be the same as the way it's on your vehicle if you don't have one of these vans. You're going to need a quarter inch drives ratchet, quarter inch is how big this drive is. You'll need an extension, this is about one and a half or two inch extension. You'll probably want you'll need one at least that long. You may want one a little bit longer but it can't be too long and then a 7/32s socket. Coils in this 98 are actually located in the back of the motor; make it a little tough to get to. This is the coil pack here and they're actually mounted back there just like this.

We'll have the- we'll zoom in a little bit. As you can see right here is one of the wires down to the first coil and then here's the other wire down to that first coil and then there's two other coils, coil packs right next. It's not too difficult, you can grab hold the wires easy enough. Pull one off, that's one on the left side as I'm looking at it. I'll pull it over here and then keep it over here and out of the way. Here's the other wire, just going to push that over there. Obviously, just do these one at a time. You can see it's in there like that so there's a bolt right here between the two post where you just took the wires off and then there's a bolt right back here underneath. You pretty much just have to do it by feel. The size of the bolt is a 7/32s standard which is a little weird. What I'm going to do is I can go back, I could feel the post first and then you go back, reach down and feel the bolt. Get my socket extension on there, make sure my ratchet is counter clockwise. We'll just speed up here removing that back bolt. I still have my socket in the extension on there, it's getting easy enough for me to turn with my hands. I'll turn it with my hands until I feel it's ready to pull up and out. There's the first bolt out. Reach in there; I could feel the two posts. Put my socket right down in between. See that you could see that right there, see the two posts and the extension socket right there.

This one, we'll just turn the whole bunch. Make sure it's all the way out and that it won't come out. I'll just leave it there and then pull the coil up. It looks like there's some interference here, the wiring harness back there. Now, I'll pull that up and right out and there's our bolt. Here's our original coil, new coil from 1A Auto, you can see the coil from one another, it's exactly the same. The original coil does have the markings of the cylinder number. This goes to cylinder number five and this one goes to cylinder number two. New coil doesn't have that. This is actually an original equipment coil but it's just meant to replace either of the three original coils. As you could see on the back, the coil does plug in when you bolt it in right there, same thing on the 1A Auto coil. This is one is working fine in this vehicle so I just will replace the original one. When you put it back in, especially on this end one there where some harness is down there, they were getting in the way. What I'm going to do is try and lift those up out of the way a little bit and put the coil back in and you want to be careful that you don't bend the contacts that are down there. You could feel them down there.

I'm going to reach in with this hand, I'm going to feel where those contacts are, I could feel them sticking up. There's a whole bunch of wires and I'm going to make sure out of the way. I'm going to feed my coil in and make sure the backside goes underneath those wires. Now what I'm doing here is gingerly moving the coil around a little bit and trying to get it to settle down on those tabs. You just want to be very careful that you don't bend the tabs at all. It's just a matter of feeling in there with both hands and getting in the right spot and then it goes right down and on. Now we'll speed up through putting those bolts in and then you tighten them up you want to tighten them up nice and snug, they don't have to be overly tight. Make sure it's tightened up. This one from that side goes on there and this one bends up and around and goes back on.
