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 remove and replace the engine ignition coils on this 2000 Buick LeSabre, same as a 2000 to 2005 LeSabre, and pretty much the same as a lot of vehicles that have the 3800 Series V6. The only tool you'll need is a 7/32"? socket with a ratchet and extension.

The ignition coils on the 3800 V6 in this Buick LeSabre is very conveniently located right here on top. When one of these starts going bad, usually what it does is it will turn the check engine light on and it will say something like misfire in cylinder number 6 or 5 or 4 or something. That's generally a good indicator that your coil is starting to go bad. If that is the case, they're pretty easy to replace. You can see that the original coils are marked here with their cylinder numbers. We know that this plug is cylinder number 3. This wire goes to cylinder number 6.What you first want to do is get these plugs kind of a twist, and then pull off. Give this wire a little bit of a twist and then pull it up and off. Then, there's two 7/32"? bolts. Remove those. We'll just speed it up here as we remove those two bolts. Once you have those off, just pull the coil straight off.

Here's the new coil from 1AAuto. Right here, there are a couple of tabs or those are actually electrical connections and they go in right there. You want to carefully equip this right now. What you can do actually is put your screw in. Make sure that goes in and then put the coil down carefully onto those tabs. It basically plugs right in just like that. Then put another screw right down in.

We'll speed things up again here as we just put those two bolts in and tighten them up. Again, tighten them nice and firm. You don't want to over tighten them, though. This was the top plug wire and then the bottom plug wire. Because the replacement coil can fit anyone of these positions, they don't come marked with the serial numbers but you could take a crayon or some type of white paint marker and mark your cylinder numbers back on there using the old ones if you wanted to.

A suggestion would be if one of your coils goes bad, obviously at 1AAuto, we sell the coils so you can buy all three. I would also replace your plug wires and your spark plugs. That's kind of a way you do a basic tuneup on these newer engines is replacing the coils, plug wires, and spark plugs.
