Pre-disconnected. We're going to come right over here to this. You can see there's a little green tab. On the other side, there's a little tab. You push that, you can draw this right off.
At this point, we're going to along to loosening this clamp, and this one right here, using an eight millimeter or a flathead.
Take a peak in here. Make sure you don't have any crud. Looks good. So now we have a clear view of the coils. You can just go down the line and start disconnecting them, by squeezing this little tab and then drawing this up.
Now I'm going to use a seven millimeter swivel. I'm going to take out the mounting bolt. It's hard to get it on there and stay. That bolt out of there. Grab your coil. Lift straight up. Make sure it comes with all the boot.
Now that we have that out, just take a peek at the boot. Make sure it isn't torn and missing a piece and it's down inside there. If it looks good, you can continue.
Before you remove your spark plug, it's important to make sure to blow a little bit of air in there to get out any crud that might be hiding out. Ooh, nasty. Before you go ahead and install your new spark plugs, make sure you check the gap on them. You want to do that very delicately. Just bring it right around and make sure you're at approximately .052. This looks great. Let's get ready for an install.
You're going to start this in by hand. You definitely don't want to have it on your ratchet yet, and you want to just feel for it and make sure it's definitely threading in perfectly. If it feels like it's nice and tight before you even turned a couple threads, more than likely it's cross threaded, and that's going to be a major issue. Okay. That just bottomed out right there. I'm going to stop. Now we're going to torque this to 11 foot pounds.
So I've got the coil here. As you can tell, it's not the best conditions. So we're just going to go ahead and replace them all with these high performance ones. It doesn't matter if you're replacing them, or your not. If you're reusing the old ones, it's going to be the same installation procedure. Grab that coil. On here. That fits beautifully. I'm just going to snug this up.
These coils, you want them to be nice and tight so that they can't spin around. If it moves a little bit, like this, that's okay. I'm just going to give it just a teeny bit more, but that's it. Last thing I want to do is break this bolt off. I'm going to go ahead and get this attached. Make sure that it's locked in. That feels good. Now I'm going to do the same to all eight cylinders.
Let's get this air intake back on. Tighten up those clamps. Nice.
So now it's going to be time to try starting the vehicle. When we do that, we want to pay special attention to up here, and make sure nothing funny happens. If you see any check engine light, which would be located right up here, we know we're going to turn it right off and check to see what's going on.
It's going to run a little rough at first, and then it will smoothen out. I'm looking up here. I see nothing in exception of just it telling me that I'm not buckled up.

Brought to you by 1AAuto.com, your source for quality replacement parts and the best service on the internet. Hi, I'm Mike Green. I'm one of the owners of 1A Auto. I want to help you save time and money repairing and maintaining your vehicle. I'm going to use my 20+ years' experience restoring and repairing cars and trucks like this to show you 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 how to remove and replace spark plugs on this 2000 Lincoln Town Car with a 4.6 liter. Tools you'll need are a 7mm socket with a ratchet and extension, a 5/8 sparkplug wrench or socket with a ratchet and extension as well, and you will also need a spark plug gapping tool.
Take an 8mm wrench and disconnect your negative battery cable. Replacing your coil and spark plugs- pretty easy. I'm going to show you on this side because it's easier to film and get to. The other side is just as easy. You do just need to remove your intake hose which is three clamps and another couple of hose connections on the back. Then you can remove that whole intake hose and get to your coils pretty easy.
The coils are held in place by a 7mm bolt. Get the socket ratchet down on there. It can be a little tough to break loose. I just want to get my socket off of here before I get too far. This connection, you just reach underneath and there's a little tab right here. Squeeze that tab and the harness pulls loose. You can just kind of pull your coil up and out like that. To get your spark plug out I've got a spark plug socket. It's a 5/8 spark plug socket. It's designed to grip onto the plug although I know mine is pretty worn out so I'm just going to put a little piece of paper towel in there and then you can put your wrench right down in. There's usually a little bit of angle. Break the spark plug loose.
Just fast forward through loosening that and then what happens is I actually get another piece of paper towel just to stuff in there to grab onto the spark plug. There's my plug. You can see these plugs are in pretty rough shape. Here's the spark plug we took out, and then here's the new platinum tip. You can see that there is quite a bit more to the new plug than the old one. This one is pretty worn out. On this Lincoln Town Car with 4.6 liter, you want to make sure that the gap between the tip of the plug and the diode is at .054. My gauge only goes to .050. So we're just going to have to just say the .004 is going to be okay which I'm sure it will be. I don't think the engine is going to mind a .004 difference in gap. What we can do is, let's see here, so we use this part of the tool to kind of bend that diode, and then we run the gauge through, and we want the gauge to basically go through and have a little bit of drag. Then that will be fine. That's .050 which is only .004 off which is perfectly acceptable. Again, I have a spark plug wrench. My wrench is a little worn out so what I'm going to do is wrap paper towel around it, stuff it into the wrench, make sure none of that paper towel was down near the threads or anything so that it sticks in there.
Now I'm going to put it down in and I'm just going to kind of lightly turn it and it goes in. When you're turning this in, it should offer some resistance, but it shouldn't be hard. If it's hard to turn you may be cross threading although it's a little hard to cross thread these plugs. Then these should be tightened to about 18 to 20 foot pounds, which is just kind of tight with the wrench like that. This happens to me a lot. I've removed a bolt, but it twisted in the socket so it's now stuck. So what I do, I take a screwdriver or something that fits right up in there, let's see here, and then I just drop it and basically that usually almost always gets the bolt from the socket. Just make sure you watch where it goes. Put is right down in. Press it in. Your 7 mm bolt. Reconnect your lead and you're all set. Just repeat that for the other seven cylinders. Then reconnect your battery and you're engine should be purring like a kitten.
