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 2003 GMC Envoy XL, with the 5.3 liter V8 engine. The items that you'll need for this is a new ignition coil from 1AAuto.com, 7mm socket and ratchet, and a flat blade screwdriver.

Because this is a V8, there's four ignition coils on either side of the engine, four here, and four more here. Each one is held in with two 7mm bolts. Start off by disconnecting the harness. Just lift up on the tab and disconnect it, and then pull and pry off the spark plug wire from the ignition coil, and then remove those two 7mm bolts. Once the bolt's removed, the ignition 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 will fit exactly the same. Wipe down the area where the ignition coil goes. Reconnect the harness to your ignition coil to help hold it into place, and then line it up on the bolt holes, and replace those two 7mm bolts, and tighten them up. Reconnect the plug wire, and repeat for any of the other coils you want to replace.
