In this video, we're going to show you how to replace an ignition coil on this 2003 Buick LeSabre. These coils are the same for many different GM vehicles, so this will cross over to different cars, although some vehicles locate the coils in different places. The only tool you'll need is a 7/32 inch socket with a ratchet and extension.

The ignition coils for this vehicle are nicely located right here on the front the engine. There's actually nothing wrong with them. I'm just going to show you how to take them in and out. Each coil does 2 cylinders. Just give the wires a twist. I'll put that one right up there; this one down here so I know which one goes where. Do these one at a time. These bolts are 7/32 inch and you just remove 2 bolts. The coil lifts right up and off. There are two contacts right here that go into the coil and then put your new one on. Carefully place it on those contacts. Make sure you don't bend them. Put your 7/32 inch bolts back in. Then plug back in your wires. The wires have to go back on the same ones, so it's important you do them one at a time and unplug the wires two at a time.
