Okay, friends. Before we get started on doing our ignition coil here, we just wanna make sure that you have safety is your number one concern. Always have your eye protection and your hand protection. Let's get started.
Let's come right over here on the passenger side of the engine. If we're looking for the coils, you're gonna see them right up along the top or side, right along here. All four going down the side and then, of course, on the other side of the engine you'll have the same four. Now, we're gonna show you on this front one right here, because it's the hardest one. And it's not very hard at all, but it is the hardest. We need to grab these heater core hoses, move them out of the way. Once they're out of the way we need to remove this bracket. Use your 10-millimeter and take off this nut.
The next thing we're gonna do is take a nice small pocket screwdriver, you can use pretty much anything, including your finger, but if you take the small pocket screwdriver, you can go right along here, lift up on this tab, and then you should be able to draw your electrical pigtail away.
Now let's move on down from the coil to the spark plug wire. Grab onto it. Give it a nice twist and pull it right off. Looking at the coil on either side, you're going to see a 7-millimeter bolt, remove both. Hold onto that coil, there's nothing holding it on there, except for this bolt at this point. There it is, friends.
Now it's gonna be time to install our brand new coil. Just gonna take it and bring it right down here, and I'm gonna line it up with exactly where I removed it from. Start in both of my bolts before I tighten either of them down. Go, both are straightened. Let's go ahead and snug them up. I always like to use a regular ratchet to make sure they're snug. Go ahead and connect in your electrical connector. Let's grab that spark plug wire. Go ahead and use a little bit of dielectric grease in there, that's gonna be helpful, and then connect it right onto your coil. Listen for a little click noise, give it a nice twist and a nice little tug, to make sure it's secured on there. You also wanna make sure that your spark plug wire is in no way touching that exhaust manifold.
So, now the replacement process for all the rest of the coils would be the same at this point. But moving along to finish up with this coil, we need to make sure we get this bracket back on. I'm gonna take the bracket, put it on there just like this. Snug it right up. There we are. Make sure it's nice and tight. Make sure you secure your heater core hoses. Double-check everything. This looks great.

Brought to you by 1AAuto.com. Your source for quality replacement parts and the best service on the internet. In this video we're going to replace an ignition coil on this 2002 GMC Sierra with a 6 liter Vortec V8. This procedure is the same for most of the 4.8, 5.3, and 6.0 liter Vortecs in the trucks as well as the SUV's, very simple, only tool you'll need is a 7 mm socket with a ratchet and extension.
The coils on this GM V8's is pretty easy to get to. There's four of them each side, eight total, one for each cylinder. They're right up here on top. I'm going to do this one because it's just the easiest one to see and film. They're all really easy to get to though. Now, there's a harness that goes in right here. I'm going to pull back on that tab and pull up and the front wire is right down here. You twist it. Hold down. Now you can see the two 7 mm bolts on each side holding it in. One here and one there. We'll just speed it up as we're removing those two 7 mm bolts with a socket and a ratchet and an extension. Our original coil, the new one from 1A Auto, you can see it's all the same. It's going to bolt in just like the original. I'm going to speed up again as I just tight those bolts in and then tighten them up with my socket, ratchet and extension. When you tighten them you want them nice and firm. They're not to be overly tight though. Put the extension back in and then plug your plug wire right back and then just repeat for the other seven.
We hope this helps you all. Brought to you by www.1AAuto.com. Your source for quality replacement parts and the best service on the internet. Please feel free to call us toll free 888-844-3393. We're the company that serve you on the internet and in person.
Tools used
Hose Pliers
Torque Wrench
8mm Wrench
Air Compressor
5/8 Inch Spark Plug Socket
Ratchet
All right, we wanna disconnect the battery, disconnect the negative cable. Use an 8-millimeter ratchet wrench or a wrench. And then slide that out of the way. We can take the spark plug wire off just on the spark plugs side. You might have to use some special pliers, like hose pliers, to get there boots off. Just like that. And just slide that to the side.
Now before you take the spark plug out, there could be some dirt and debris around the plug. Just take some compressed air and just spray right around the plug itself. And take a spark plug socket. This happens to be a 5/8 spark plug socket. And loosen the plug.
And slide the plug out. Take the new spark plug, put it in your spark plug socket and just carefully line it up. And you wanna torque this to 11 foot-pounds. And reconnect the spark plug wire, just line it up with the plug. Lock it down and then you can do the same procedure for the other ones.
Now we can hook up the battery. Line it up, get it started. And snug it up. Just make sure it's not loose. That's good.

Dielectric Grease

All right. We want to disconnect the battery. Disconnect the negative cable, use an 8-millimeter ratchet wrench or a wrench, and slide that out of the way. All right. Now, replace the plug wire. Just grab the top of the wire, pull it down. And then, at the spark plug, you can try twisting this first. See if you can loosen it up. Try to pull it. Try not to bend the aluminum too much, but if you're struggling to get it off, you might have to a little bit. There you go. Pulled that one out.
You can take a little dielectric grease or some silicone lubricant. Just put this in the end right here. Then, you want to take the heat shield off the old wire and reuse this. Now, we can line this up, up top on the coil. And then line it up with the plug. Slide it in position. Make sure it clicks in place, just like that. Then you're going to do the same procedure for the other wires.
Now, we can hook up the battery. Line it up, get it started, and snug it up. Just make sure it's not loose. That's good.
Not many more miles driven on the truck since installation, but so far so good. Before the swap out I was having "labored start" issues requiring multiple cranking attempts; happy to report that the new products corrected that issue. Installation was challenging, some plug/coil components being quite hard to remove/replace, so the rating is for the products and NOT the project.
Good

Plug and play, the kit had everything I needed including the wires pre-greased with dielectric grease. I purchased them with iridium plugs that I had to adjust the gap of two of, but generally they all were set to specifications!
Good fit for 5.3 vortec engine

Parts for tune-up of my 2001 Silverado all appear to be of high quality and fit like OEM. The first order I received for my truck came with wrong coil packs (probably my mistake). I contacted customer service and the were very helpful to process the return of the original parts and exceptional about making sure my re-order included the correct items. Thank you 1A Auto and a special thank you to the customer service rep who helped me out.
A very happy customer and student!
