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.

The spark plug wire were 2" short. The ignition coils had mounting brackets holes in wrong place and wouldn't mount. Horrible product to buy.
