Hi, I'm Don 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're going to show you how to replace an ignition coil on this 2002 Chevy Suburban with the 5.3 liter, V8 engine. It's the same part and similar process on these Suburbans from 2000 to 2006. The items you'll need for this are a new ignition coil from 1AAuto.com and a 10mm socket and ratchet with an extension.
Your ignition coils are located right here. There are four on each side since this is a V8 engine. To remove these ignition coils, it's the same process for each of them; they're held in with two 10mm bolts. The only difference is this one right here that has a bracket for these hoses over it and that bracket also just held in with a 10mm bolt. We'll show you on this one since it's a slightly different procedure. Just lift up on the tab and disconnect that harness, and then, using a 10mm socket and ratchet, just remove that 10mm bolt, right there. Now you can just pull that bracket aside, and then, pull your spark plug wire from the ignition coil. Then remove the 10mm bolt at the top and the bottom of the coil. The coil will pull right off.
On the left, is the old ignition coil; on the right, is the new one from 1A Auto. You can see they're identical and they're going to fit exactly the same. Take your new ignition coil and push it down into place and then replace those two 10mm bolts. We'll fast forward as Don does this. Now reconnect your spark plug wire and then push this bracket back into place and replace that 10mm bolt. If you're replacing multiple ignition coils, obviousl,y you just repeat the process for each one and finally just reconnect the harness and you're all set.
We hope this video helps you out. 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's here for you on the Internet and in person.

Coil paks for my Silverado
Ken

Easy swap out, but the details on the web site are misleading. They note the 8th VIN digit for parts match. The first order I received based on that info was incorrect.
The great news is 1A overnighted the CORRECT part at their expense! All I can say is WOW! WHAT GREAT CUSTOMER SERVICE!
LOVE THIS COMPANY!
