How to Replace Spark Plugs 98-12 Ford Crown Victoria

Share on:

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.
