2004 GMC Envoy XL V8 5.3L 9 Piece Ignition Kit DIY Solutions IGN01171

You can move these heater hoses out of the way, just pull them out of the bracket and slide them to the side. Take the wire off the spark plug. You can twist it a little bit. It might help. And then try to pull it off. It's a good idea not to pull on the wire itself. Just try to pull on the base and you can slide this out of the way.

Before we take the spark plug out, just take a little compressed air and just blow around the plug. There may be some sand in there or dirt or debris, get that out of the way. And take a spark plug socket. It's a 5/8 spark plug socket. And you can use and an extension and take the spark plug out. And slide the old spark plug out.

Take the new spark plug. Put in the spark plug socket. And then gently, feed it over to where the hole is and just by hand, screw it in. And we can torque that to 11 foot-pounds.

You can always put a little bit of dielectric grease in there and then slide this over the spark plug. Make sure you lock it in place. And you do the same with the other ones. And move these heater hoses, put them back in the bracket.

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 the spark plug in this 2005 GMC Savana 2500. The only tools you're going to need are a 10 mm socket, a 5/8 socket, and a ratchet.

To start it off, go to the driver 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 is 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, again, there are two more 10mm bolts securing the 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. We'll fast forward as he removes these two 10mm bolts. Now, you just want to pry this panel off. It'll pry off pretty easily.

Now in the center of the center console underneath, there are 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 these unlatched, just lift up and pull forward. It'll pull right out. Now, to make more room for yourself, the engine is behind this panel, so what you can do is you can see you can't come out of this vehicle; the seats are in the way. 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 this. 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 the overall access panel being shorter, you can push it under the dash. Now, you can access those spark plugs and ignition coils. We'll push it under the driver side. Now, you can see the other spark plugs and ignition coils.

Now, we're going to just show you how to change one spark plug, but they're all the same pretty much. You just want to pull out the spark plug wires and stick your 5/8 socket up into the hole there and just start twisting out the spark plug.

Now, with your new spark plug, you want to use a gap tool, and you just want to make sure that the gap on the spark plug is the right size. In this case, we would want .060.

Now, to install the new spark plug, you just want to put it into the socket, and then feed it down into the hole and twist the spark plug in by hand. It's a lot easier to line it up this way. You just want to twist it until it's firm and then reattach your ratchet and tighten it the rest of the way. Most of the plugs are reachable from the back. As an alternate, some of the front ones you may want to go in through the wheel well. That may be able to give easier access, but you want to plug the wire back in and then repeat seven times for the other plugs.

So, to put the panel back together, what you want to do is you put that top piece on and line up the access panel, and you just want to keep pushing it back into place, and what you'll see is 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. So, 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, so put it into place and place those four 10mm bolts. It helps if you do it by hand. You can hold onto it, line up all the bolts. Just start it out by hand and then we'll fast forward as he uses the ratchet to tighten them the rest of the way. Now, you can put on that little panel right there. It just clips into place. Now, replace the panel underneath the driver side. Just push all the clips in. You should hear them snap, and then you just want to replace those two 10mm bolts, and we'll fast 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're all set.

Okay, friends. Now, before we get started on this spark plug video, we want to go over a couple brief things. The number one concern is always safety. Make sure you're wearing hand protection and eye protection at all times. The next thing I wanna talk about involves the spark plug directly, and it's located right here. It's the gap between the electrodes. You wanna make sure you have a gap there, and the gap for this vehicle should be 0.040. You can get yourself one of these gap tools, maybe it'll come in handy. One thing about using a gapping tool is that it's made out of hard metal, and these spark plugs right here are made out of precious metals on the end by the electrode. If you shove this hard metal in there, you could potentially damage it. So maybe you could just put it up close, see if it looks like it's approximately right. And you could also compare it to the rest of the spark plugs and make sure they are all approximately the same going across. Once you've confirmed that they all look fine, let's continue with the install.

Now in this video, we're gonna be showing you how to do the front right spark plug, but the process will be the same for all. What we're gonna need to do is remove the lower part of the spark plug wire from the spark plug. You wanna be very careful that your engine is not hot because this is your exhaust manifold. Give it a nice twist, see if you can break it free. If you can, twist and pull, should come right off. I always like to take a peek to make sure that there's no damage, there's no moisture, and there's no corrosion. That looks like it still got some lubricant on there, so that looks great.

We're gonna take our 5/8 spark plug socket, and we're gonna come right down, put it onto the spark plug, gonna give it a little spin, you should feel a click in, go ahead and turn it to the left. I'm only gonna give it a couple turns and then we're gonna use some compressed air to make sure we blow out any debris that might be in there.

Let's just take a quick look at that spark plug. Look at the condition. Does it look as though it's got funny colors? Maybe it has buildup of any sort? If you see buildup, you know that you're not burning proper fuel and, of course, your new spark plug's probably going to get buildup over time as well. This one looks fairly decent and it's not worn at any angles. I don't see that there would be any issue. Let's go ahead and replace it.

So, we've got our old spark plug, let's grab our new one. And we're gonna look right along this edge right here. That's where it's gonna mate to the engine, you wanna try to compare those together. And then come right up along the top where the electrode is, make sure that it comes out to the approximate same length. If for some reason your new or old spark plug was higher or longer than the other, you know you're probably going to have an issue. More than likely you have the wrong spark plug.

Once you know you've got the correct spark plug and it's gapped as close as possible, let's go ahead and carefully install it into the engine. Just wanna find that hole, guide it in. Always start it in by hand, and you never ever wanna use an air gun for any reason doing spark plugs.
We're gonna go ahead and torque down. When you torque it, if you're torquing it into an old head or a used head, you would torque it to 11 foot-pounds. If you're going into a brand new engine or a brand new head, torque it to 15 foot-pounds.

Now it's gonna be time to get your coil wire back on here. Before you do that, I just like to say, it's always a great idea to replace your spark plug wires when you're replacing your spark plugs. Either way, whether you're replacing them or not, I definitely recommend using some dielectric grease right along the area that's gonna go over the spark plug. That's gonna help this release easier next time. Go ahead and slide it on there. Make sure it clicks in. Beautiful. Follow the wire, make sure you didn't give any tugs and it's not going anywhere near the exhaust in any way. Do the same for all the rest.

These are where your spark plugs are on this 2009 Chevy Suburban. It's the rearmost one of the driver's side. We have four in each side. One, two, three, four. We go over to the passenger's side. This one is a little bit trickier to get to. It's in the way, way back. We've got back there, one here, one here, and one here. It'll be just enough room to get it. We're going to show you how to replace one on the driver's side front. This procedure is going to be the same for all of them. It just might take a little more maneuvering to get to the other side.

I'm going to give this a little turn, and then you don't want to pull on the wire. All you've got to do is work it off of the electrode and of the spark plug. It's usually on there pretty tight. I should also mention that you should do this when the engine is cold because we're right next to the exhaust manifold. Just put this to the side. You should do these one at a time.

Spark plug is down here in the head. I'm just going to take some compressed air. Just blow around the spark plug. If you don't have that, it's okay. Just be careful. Maybe take a brush. You just don't want anything falling down into the cylinder when you open up the spark plug hold. These spark plugs are going to take a five-eighths socket. You want to get a spark plug socket. This is a regular five-eighths socket. If you put a spark plug in here, it's real, real loose, and you can turn it while you're trying to install it. The spark plug is going to fall out.

A spark plug specific socket has a rubber insert to grab on to the foursome part of the spark plug so when you put it in here, it seats. You can go to install it. It's not going to fall out and the same when you're using it to remove old spark plugs. You can lift them out of the engine and they won't fall down. We're going to use a three-eighths drive and my five-eighths spark plug socket. It should be on there.

Take my ratchet. You're going to remove it. These are only torqued to eleven foot-pounds, so it shouldn't take much effort to get them out. Once it starts to get loose, you can remove the ratchet. We just use our fingers to spin it out. As you remove it, the spark plug socket is going to hold it in place so if you need to move it around, you're not going to drop it.

So you can see this is our old spark plug and this is our new one from 1AAuto.com. Their threads are the same length. A single electrode. These are going to work great and give you nice performance on your vehicle.

Take our new spark plug and put it into our spark plug socket. Carefully place it into a spark plug opening. Sometimes if you go backwards, it helps you find the threads and then you can spin it forward to go in. It should go in very, very easily. If it feels like it's cross-threading, you should stop and make sure that it's going in nice and straight. Okay. Now that you've got it hand-tight, we're going to torque it to eleven foot-pounds.

The spark plug torque can reinstall our spark plug boot. Just push it on as hard as you can and just check that it's seated.
