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 replace an ignition coil on this 2003 GMC Envoy XL, with the 5.3 liter V8 engine. The items that you'll need for this is a new ignition coil from 1AAuto.com, 7mm socket and ratchet, and a flat blade screwdriver.

Because this is a V8, there's four ignition coils on either side of the engine, four here, and four more here. Each one is held in with two 7mm bolts. Start off by disconnecting the harness. Just lift up on the tab and disconnect it, and then pull and pry off the spark plug wire from the ignition coil, and then remove those two 7mm bolts. Once the bolt's removed, the ignition coil will pull right off.

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 will fit exactly the same. Wipe down the area where the ignition coil goes. Reconnect the harness to your ignition coil to help hold it into place, and then line it up on the bolt holes, and replace those two 7mm bolts, and tighten them up. Reconnect the plug wire, and repeat for any of the other coils you want to replace.

In this video, we're going to show you how to replace the ignition coil on this 2005 GMC Savana 2500 with the 6 liter V8 engine. The tools that you'll need are a 7mm and a 10mm socket and ratchet.

To start off, go to the driver's side of the vehicle and you'll see there is a panel right here and you're going to want to remove these two 10mm bolts that secure that panel and also you'll see that there's a latch back here. Pull that back towards you and it should unhook that clip there, and then you just want to remove those bolts. We'll just fast forward as he does this. Now, with the bolts removed, you can just pull on that panel. Just reach underneath it and pull it out. Be careful not to pull out the panels above it. Now, on the other side, there are two more 10mm bolts securing a panel. You want to just remove these two 10mm bolts and also, like on the other side, you want to pull back this clip and unlatch that and we'll fast forward as he removes these two 10mm bolts. Now, you just want to pry this panel off. It should pry off pretty easily. In the center of the center console, underneath, there's two more of these latch clips and what you want to do is, you want to just push up on the clips and free them, and then, once you have this unlatched, just lift up and pull forward. Pull right out. To make more room for yourself, the engine is behind this panel. What you can do is, you can see it can't come out of this vehicle. The seats are in the way and the seats are only a few bolts if you want to remove them, but if you just want a little bit more room to save time, what you can do is you can just remove . you see these four 10mm bolts inside this panel. You just want to remove those. With those bolts out, you can now pull that panel up and off and remove that little top piece and now, with put the overall access panel being shorter, you can push it under the dash and then you can access those spark plugs and ignition coils. If we push it under the driver's side, you can see the other spark plugs and ignition coils.

We drew up this diagram to help you out. If you have a code reader and know what ignition coil is misfiring, this will tell you which ignition coil that is on your engine. The driver's side, front of the engine spark plug would be one and then it goes back three, five, and seven. On the other side is the evens and it goes two, four, six and eight. In this video, we're going to show you how to replace number eight, but it's the same process for all of them.

Here is ignition coil number eight. You just want to disconnect the harness and remove these two 7mm bolts. There's one on this side and then there's another one just opposite of it on the other side and we'll fast forward as he loosens and removes these. With the bolts out, the ignition coil comes right off and you just unplug your spark plug wires.
Then, get your 7mm bolts and tighten them in by hand to secure the ignition coil in place. Once you have that secured, just use the socket and ratchet to tighten it the rest of the way and we'll fast forward as he does this. Now, you just want to reconnect your ignition coil, just plug in that harness up there and plug in your spark plug wires.

To put the panel back together, what you want to do is you put that top piece on, line up the access panel and you just want to keep pushing it back into place. What you'll just see, you'll see those clips have to line up. There are hooks on the van, on the floor of the van that you need to line the latch hooks up with. Once you have it lined up, you just want to start connecting all those latches. Just hook on to the hook, pull the tab and lock it and you want to do that with all four of them. Now, you can replace the cup holder panel. Just put it into place. Replace those four 10mm bolts. It helps you do it by hand. You can hold on to it and line up all the bolts. Just start it out by hand and then we'll fast forward as he uses the ratchet to tighten the rest of the way. Now, you can put on that little panel right there. Just clips into place. Replace the panel underneath the driver's side, just push all the clips in. You should hear them snap. Then, you just want to replace those two 10mm bolts and we'll faster forward as he does this. Now, you just want to push that panel into place on the passenger side. You just want to line up the clips, push it in and then replace these two 10mm bolts and then you are all set.

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.
