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.

Thought I had lifter tick but after Installing this kit the ticking went away. Turns out my plugs n wires were so bad they were arcing on the block making a ticking noise. My tahoe feels stronger and smoother in general too.
TRQ? Seem to be good parts so far.

Direct replacement seemed to be very good quality. I could tell an immediate difference as soon as I cranked it up.

Exactly as described, fit perfectly. My only wish would be that the actual plug wires themselves were about 1/4-1/2" longer?.. other than that, great buy! No check engine lights no misfires, they work just like OEM or better. (2001 Chevy Silverado 1500 Lt Base 4.8L 4x4 standard cab short bed.)

The parts are the correct parts, they also fit just fine. My truck did not run very well with the ignition coils, wires, and plugs.
Just hope by give them a good review they hook me up with.
