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.

Iridium sparkplugs.

After using NGK iridium plugs in my motorcycles and atv's the overall performance was appreciable. The complete burning of the gas made it cleaner and lasted much longer than conventional plugs with no fouling. So I found them for my truck and now it runs like a new one with plenty of people.

The spark plugs in my truck had not been replaced in years. So when it was time to replace them I relied on 1A Auto as my auto parts supplier to get my parts from.
They arrived within s few days and fit without issue. The truck ran better than ever before and my MPG greatly improved

My check engine light was on and my engine had a rough idle. Could feel it missing while driving. Ordered new plug wire set and new plugs from 1A auto and this fixed my problem. Check engine light went out shortly thereafter. Engine runs smooth now and idles fine.

Thank you for your inquiry. These will come pre-gapped and ready to install, however, it is worth double checking to be sure nothing changed in transit. Please let us know if you have any further questions.
