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 are going to show you, we're going to show you how to replace a spark plug in this 2002 GMC Sierra 2500 HD. It's pretty much the same process with most V-8 engines. And the only tools you're going to need for this vehicle is 5/8-inch-deep socket or a spark-plug socket and a ratchet, and you're also going to need a gap tool.
Okay, so because this is a V-8 engine, it has eight spark plugs. There's four on this side and four on the other side, and in this video, we are just going to show you how to change one of them, but it is pretty much the same process for all eight. Okay so, using your gap tool, you just want to make the gap on the spark plug the proper size. In this vehicle, it is .06. You just want to use the pegs on this pry out the gap on the spark plug until you get it so that there's just a little bit of resistance as it slides on to the proper size. And there it is.
Okay, so you just want to reach down to the spark plug you're changing and disconnect the spark plug wire, and then using your 5/8-inch-deep socket or a spark-plug socket and a ratchet, you just want to twist that out. And then just remove that spark plug. Okay, and then what you want to do to replace it is just put that spark plug right into the socket, feed it down into the hole and just twist it until it's threaded on there. Once it's threaded, you just want to use your ratchet and tighten up that spark plug the rest of way. Generally, you want to tighten them to about 20 to 25 foot pounds. Then remove your socket and put the spark plug wire in place and just repeat that process for the other seven spark plugs.

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.

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.
