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.

I want to help you save time and money repairing and maintaining your vehicle. I'm going to use by 20 plus years experiences restoring and repairing cars and trucks like this to show the correct way to install parts from 1AAuto.com. The right parts installed correctly, that's going to save you time and money. Thank you and enjoy the video. In this video we're going to show you ignition coil replacement. This is an '03 Monte Carlo SS with a 3800 or 3.8 liter. The same engine that's in a ton of different vehicles from the late 90's to the late 2009, 2010 era. The same procedure for all vehicles. The only tool you're going to need is a socket and ratchet with an extension, either 6 mm or a 7/32.
Coil replacement, this is a 2003 Monte Carlo SS. It has got a 3800 V6, pretty typical of a lot of GM cars, great little engine, good power, lasts a long time. The coils for the most part are right on the side of the engine, right here. You can see that there are three of them. Each coil handles two cylinders, so they're really nice and easy to get to on these V6's. This is pretty much the same as the 3.4 liter V6 as well. I'll show you how to replace these. Okay, replacement is really quite easy. You start by removing the plug wires and I do one coil at a time. You don't want to just unplug all these wires. You want to make sure you have to plug them back into the same spot.
I just unplug. I take that one and leave it right up there. I'll take this one that's lower and I'll put it down here. Now I have two bolts here that I have to remove. Okay, those two bolts are 6 mm and actually 7/32 and a standard socket works as well. Okay, then the coil comes right off. You can see that it plugs into two tabs right there. You want to be careful when you raise not to bend those tabs at all. Okay, this is our original coil. This is our coil from 1A Auto. You can see that they're the exact same. Obviously our coil doesn't have the numbers on it; because, it can be used on any of the three positions. Everything's the same. Everything is going to bolt in the same. It has the same plugs there. I am going to re-install the original coil; because, there's nothing wrong with it on this car. I just wanted to show you that.
A good practice when you're re-installing the coil is to put these bolts in, okay. That way when you put it down on you can see that the bolts go into the right place and that you have the coil lined up, okay, so then just kind of lightly work it down on there. Then push those bolts on. I'm going to tighten up with my air ratchet. Now I'm going to finish tightening it up by hand. Never want to use the ratchet to tighten something up; because, you want to know how tight it actually is. Okay, I know I left this top one up here. I'll put that one on and then this bottom one down here. I'm going to put that one on. Just repeat that for the other two.
