1. Removing the Engine Cover
Remove the four 5mm Allen bolts from the engine cover
Lift the cover off
2. Removing the Ignition Coils
Push in the clip and disconnect the connector
Remove the 10mm bolt from the ignition coil
Lift the ignition coil up and out
3. Removing the Spark Plug
Loosen the spark plug with a 5/8" socket and extension
4. Installing the Spark Plug
Insert the spark plug into the socket
Tighten the spark plug into the engine by hand
Torque the spark plug to 15-21 foot-pounds
5. Installing the Ignition Coils
Insert the coil into the engine
Tighten the 10mm bolt to the coil
Connect the connector
6. Reinstalling the Engine Cover
Place the cover over the engine
Tighten the four 5mm Allen bolts
Use a 5mm Allen key to remove the plastic engine cover. There are one, two, three, four bolts holding it on. Lift that off and put it aside.
These are your four ignition coils. I'm going to show you how to remove this one, procedure will be exactly the same for the other three. Start by pushing this clip in and wiggle the connector out. Use a 10mm socket and ratchet and use a retaining bolt. Put that bolt aside. Grab it on both sides, and kind of wiggle it, because there is a boot that goes down over the spark plug. It's got a little suction to it. Pull it out and that's how you remove the coil.
Your spark plugs are located down in the head through these access holes. Before you remove the spark plugs from the holes, to make sure there's no debris in there, if you've got access to compressed air with a blow gun, you should blow the holes and blow out any debris so you don't have any fall into the cylinder with the spark plug pulled out of there. These ones are actually pretty clean, so we're in good shape.
We can use a 5/8 spark plug socket. It has the little rubber holder in here that's going to grab onto the electrode end. It'll allow me to pull the spark plug out of the cylinder head once it's loose. We can just do these one at a time. Pull one out, replace it with the new one, move on down the line. Your old spark plug we pulled out, it's pretty dirty and sooty and it's got a bit of a fuel odor. The car actually had a check engine light for a random misfire. So it seems like it's time for a tune-up.
This is our new spark plug from 1AAuto.com. It is an exact match for the one that came out of the vehicle. It's ready to go and be installed. The electrode is nice and fresh and it's not worn out. This will really help the car out and basically be like driving a new car again.
Take our new spark plug, place it into the spark plug socket. That's why it has the little rubber holder in there so it doesn't fall out while you're trying to install it. Just going to install it by hand so it doesn't get cross threaded. Once I've swapped out all of them, I'll come back and torque these. Thread it down until it stops. Move to the next one. With the plugs threaded in just hand-tight until they stopped, I'll now torque them. The torque is 15 to 21 foot-pounds. I'm going to set my torque wrench at 17. We'll torque them down.
This bolt hole is just a metal insert into this plastic valve cover, so we're not going to over-tighten those. We'll tighten them very carefully so slide the coil down, push it over the spark plug, and let it sit in there. Get the bolt started. Just using my wrist to tighten it. Right when I feel it get tight, I'm going to stop because I don't want to pull the serrated insert out of the plastic valve cover.
Reinstall the connector, and repeat this procedure for the rest of the coils. Reinstall the engine cover, reinstall your four bolts. These bolts are just going into aluminum, just holding on a plastic cover. Not a lot of torque on these. Job is complete.

Hi, I'm Don 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 replace the spark plug on this 2003 Nissan Altima with the 2.5 liter, 4-cylinder engine. The items you'll need for this are new spark plugs from 1AAuto.com, 10mm socket and ratchet, 5mm Allen bit, and a 5/8 inch spark plug socket, as well as a gap tool.
To access the ignition coils, you first have to remove this engine cover. It's held in by these four 5mm Allen bolts. We'll just fast forward as Don removes these. Now, the cover just lifts right off. Here are your four ignition coils. It's held in with one 10mm bolt and the harness right here. Just push the tab and pull that harness off, and then remove that 10mm bolt. The ignition coil just lifts right up and out. With the ignition coil removed, you can see the spark plug right down in there. Using an extension and your 5/8 inch socket, you want to just remove that spark plug. If the plug doesn't come right out, then you can use a magnet or pliers to reach down and grab it.
You'll want to set the gap between the center electrode and the ground electrode. On this, it should be .044. Set it by sliding the spark plug tool in between there and make sure there's a little resistance when you pull it in and out.
Carefully, put the spark plug back down in and thread it in by hand to make sure you don't cross-thread it. Once it's seated, you want to tighten it between 18 and 20 foot pounds. Now, put your coil back down in and replace the 10mm bolt. You'll want to reconnect it and repeat these steps for the rest of the spark plugs.

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 replace the spark plugs on this 2006 Nissan Sentra. This vehicle has the four-cylinder engine. The only tools you'll need are a 10 millimeter wrench or a socket with ratchet, and then you'll also need a 5/8ths spark plug socket with a ratchet and extension.
Pretty easy, they're right straight forward. A 10 millimeter bolt holds the coil in. Remove that. Pull on here, and disconnect. The coil comes up and out. You want at 5/8ths plug socket. This is actually designed to kind of go on, it's got a soft center. It kind of grabs on to the coil. Mine is really old, so I'm going to stuff a piece of paper towel up in there, which, will help it to grab onto the socket. So, you just put it right down in until it's on the spark plug. Get it nice and firm and unscrew the plug. Try lifting up on it slowly, and it should come right up and out.
When you put new plugs in, the new plugs should come already gapped. These platinum tipped plugs, you have to be very careful with them when you gap them. These should be at .044 or 44 thousandths. Like I said, they should come gapped, but if you want to check them, just take your gage and carefully and slowly insert it. It should insert. Then, come back out with just a little bit of resistance. Once you've made sure you're all set with your gap, then put the plug back down in. Carefully, make sure when you're turning, that you have your extension right in the center of the hole so that your plug's going in straight. Then, tighten and these should be tightened to about 25 to 30 foot-pounds, which is, just kind of firmly tightened with a smaller handle like this. You don't want to over tighten them. They'll get stuck in the head very easily. Okay, here's a new coil from 1A Auto; it's going to go in just like the original one. Making sure that you put it right down in the center there. You can feel it kind of go down to the spark plug. I'm going to put it down on. Put your bolt back in, and tighten it right down, nice and firm. Reconnect, and then repeat for the other three.

What's up, guys? I'm Andy from 1A Auto. In this video, I'm going to show you how to replace the spark plugs in this 2010 Toyota RAV4. If you need parts for your vehicle, click the link in the description and head over to 1aauto.com.
Just want to pull this cover off. Just grab underneath the cover, slide up, and that up there and there. These retainers that hold it in, just push on little grommets right on those locations. This is where your coils are. There's four of them on this particular engine, so I'm going to show you how to do this one. Just disconnect the connector right here. Just push down on the lock tab and slide it out just like that. Take a 10mm socket extension and ratchet, loosen up this bolt right here. Take that bolt out. We can grab the coil. Sometimes you just twist it a little bit and slide it out. Now, this seal got stuck on there, so you want to take the seal off. Just put it back on the coil, and there's the coil.
Before I pull the spark plug out, if there's any dirt or anything in there, it's a good idea to just take a blow gun and blow out anything in there. Get any dust or dirt out of there. You don't want any of that going down into the cylinder. Now, you want to take a spark plug socket. The reason you want a spark plug socket is because normally inside there there's a rubber grommet that's going to hold the spark plug from falling out, so once it's loose you can pull the spark plug out. Sometimes there's a magnet on there, depending on the socket. Use that plus an extension and a ratchet, and you don't want to do this with any power tools because you could strip stuff out. It's better off just doing it by hand.
Once that's loose, you can slip it up and see the spark plug comes right out with the socket. Here's the old part. Here's the new spark plug from 1aauto.com. This is made by NGK. The plug lengths are the same. The important thing you want to keep in mind is the depth of the threaded part of the plug, which it's the same. These plugs come pre-gapped, so you don't have to gap them. Get yours at 1aauto.com and you'll be ready to rock and roll.
Take the spark plug, put it in your spark plug socket so it doesn't fall out, and then carefully lower it down. Remember, you don't have to gap them, they come pre-gapped, and start threading it. Now, if you dropped it, then obviously you need a new spark plug because the electrode is probably going to be touching, so just keep that in mind. Don't drop them. Snug it up just a little bit with the ratchet, and then I'll take a torque wrench and torque to this 18 foot-pounds.
Now, there is a crush washer on there, so it might move a little more than you would think it would. That's good. Pull that out. Sometimes the spark plug socket gets stuck in there, so just wiggle it around and you're good. Just make sure the rubber grommet didn't come out. I'm going to take the coil, I'm just going to take a little bit of dielectric grease, just put a little bit in there. It's always a good idea. You don't necessarily have to, but it helps. Take the coil, slide that in position. That's good.
Take the 10mm bolt, get that started. Just take a 10mm socket and ratchet and just snug this down. It's good. Take the connector and line it up and lock it in place, and then you're going to do the same with the other ones.
Take this cover and we want to line these little tabs up with these little pins right there. There's three of them. Just push it down and then you're good to go.
