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're going to show you how to replace an ignition coil on this 2011 Chevy Silverado 1500 with the 5.3-liter V8. It's a similar process on a large variety of GM models from 2007 to 2012. The only tool that you'll need for this is a 10mm socket and ratchet.
We're just going to show you on this ignition coil right here, but you can see there's four on either side since it is a V8. What you want to do first is just disconnect the harness at the top, and then remove these two 10mm bolts right here. Once those screws are out, you can pull the ignition coil away and just disconnect the spark plug wire.
Take your new ignition coil and put it back in place. Plug that harness back in at the top, line up those holes, and replace those two 10mm bolts. We'll speed up here. Notice he threads them in first by hand, and then tightens them up with the socket and ratchet. Then reconnect your spark plug wire and you're all set.
