Hi, I’m Mike from 1A Auto. We’ve been selling auto parts for over 30 years!

These heavy engines have eight ignition coils, and each coil does two spark plugs and there's two spark plugs in each cylinder. We're going to show you how to remove this ignition coil. This is probably the easiest one on the engine to do. The one on the driver side rear, actually two of the ones on the driver side rear are pretty difficult. But we're going to start with this one and just show you how it comes out, and then we'll give you some tips later on how to do the driver side rear.

We'll start with removing these two 10 millimeter screws. They are really easy to come out. As soon as you crack them loose, you can just spin them up by hand. Then up here you have just a clip that you can push down on and release from the coil. All right, if pushing it down with your thumb doesn't work, you can always go with the screwdriver and just kind of wiggle it up. There we go. With the two bolts out of the way and the connector loose, you can slide this right up and out, and you can see it has these two boots on it. These boots can actually come off as well. They may come off when you do the driver side rear because pulling this out with these boots attached is really, really difficult.

All right, we're now going to slide this right back in. You want to make sure your connector is facing up so you can plug your plug in. Technically removing this engine cover will make it a little easier on yourself. But it's not necessary for this specific coil. All right, the connector's plugged back in. Now we can put these two 10 millimeters right back in the holes. With them tightened by hand, you can go back with your socket and ratchet and just kind of snug them up. You don't need to go too crazy with this. Just making them snug is perfectly fine.

Now if you've ever had to do spark plugs or ignition coils on one of these engines, you know that the driver side rear two ignition coils and all four of those spark plugs are really difficult to access. We would love to show you how to do that, but getting the camera in there to see anything is really difficult. I'm just going to give you a few tips on what I've done in the past to get these things out. A few things you can use are a ratcheting 10 millimeter wrenches to get the coils.

You can reach back, and if you remove this engine cover you have a little bit more swaying room. So you can use a 10 millimeter wrench, if you have a ratcheting one, that one's even better. And then you can get the bolts out. The other thing you can use is quarter drive socket with a swivel on the end, and make sure it's a shallow socket and you should be able to reach in and you can get some of these hard to reach 10 millimeter bolts.

Then once you do get those two 10 millimeters out of each coil, and you remove the plug on the top. You can just bend the coil out of the way because the boots are flexible. The only thing you have to watch out for is when the boot comes off there's a little tiny metal pin inside the boot and that's going to fall and you might lose it. So you have to be prepared to have that little pin pop out of the boot if you are going to remove the boots with the coil being separate. Those are a couple of my tips. It's definitely a challenge to do and it'll take a while, but hopefully that'll help you out and get you fixed up right.
