Hey, friends.
It's Len down at 1A Auto.
Today, we're going to be working on a 2010 Nissan Altima.
It's going to be a very simple job and we're going to be replacing spark plugs.
If you need any parts, you can always come down to 1A Auto and check us out.
Okay, now we've got our hood open, we're going to go ahead and use our 5 millimeter Allen
head socket and we're going to remove three bolts.
There's one here, there and there.
Start at whichever one you want, but basically, we're taking them all completely out.
All right.
So we got the last bolt out.
Feels pretty good.
I'm going to go ahead and lift up on this.
If it feels like it's stuck, more than likely, one of the bolts didn't come all the way out.
If you want, you can remove these completely from the cover, but I'll just leave it in
and set this aside, and we can move on to our next step.
Now what we're going to do is we're going to pull off all our coil wires.
This is your spark plug coils.
They sit on top of where the spark plug's going to be.
So what we're going to do is we're just going to squeeze this little tab.
If for some reason you don't have the finger strength for it, you can use a small screw
driver.
We're just going to squeeze it, try to pull.
If it seems like it's stuck, like I said, we can try to use a small screw driver.
That's okay.
You hear a little click.
Pull that right off.
Next, you want to look inside.
This is where it makes the connections to the spark plug coil.
If you see green or brown or any other color but shiny metal, that's going to be an issue.
So at that point, you'd want to replace this.
Coming down the line, we're just going to go ahead and remove this one.
Same thing.
You can try to squeeze that.
If you can't pull on it, you can use two screw drivers if you need to, but you can also give
it a little pry.
Separate it.
Try to give it a tug just like that.
If for some reason you can't get enough pull because this is secured, you can remove these
clips.
You just use some little pliers and then you can pull it off.
I'm not having too much of an issue, so I'll continue.
I'm going to go ahead and do the rest of these too.
Okay, so I've got all these off.
I inspected them, but something that I did want to mention is, as I told you, if you
wanted to take this out so you could get it easier, it's very simple.
You can use some pliers.
I have these in my hands, so this is what I'll use.
I'll just give it a little squeeze from side to side, and pull it away.
I would do the same for this and that would give us plenty of slack.
Just give it a little squeeze.
Give it a little pull.
Look at that.
So, if you did need more slack, you were having an issue getting it off, that's all you'd
do.
You just squeeze those two tabs from side to side, very simple, and then give it a little
tug.
Next, we're going to remove these 10 millimeter head bolts.
You can use a ratchet.
You don't need an air gun.
That one, we'll put it out of the way where we won't lose it and do this to all four.
Like that, I'll show you what they look like.
All four are the same.
They don't look like they're rusted or rotted or anything like that that we'd need to replace.
So we're clear to put these aside.
We'll move onto to removing these coils.
To do this, you can just give it a little shake side to side, do them all if you want.
They feel good and then lift it up.
You're going to inspect right in here.
See if you see any funny colors.
Rainbow colors are bad, you want to look for metal and then right along here, this is a
seal.
It keeps moisture out.
Make sure that that's not cracked, dry rotted, swollen.
This looks great.
We're going to do the same thing for all four of them.
When we pull them out, we're going to keep order of which one goes where.
You don't want to put this one here, that one over there.
We're just going to go like this.
We'll pull them out.
We'll go right in a straight line.
It's easy to remember.
We've got our coils out.
We checked all the boots.
We made sure everything's good.
Next, we're going to want to to start removing the spark plugs, which are located inside
these holes.
There's four of them.
This is a four cylinder engine.
What we want to make sure is we want to look inside and see if there's any water buildup,
rust buildup, dirt buildup, anything, really, that shouldn't be in there.
If they don't look like they're clean, what you can do is you can take your air gun or
a blow gun, I should say, and you want to blow air in there.
You want to make sure you're wearing safety glasses for this.
It's very important.
We're going to blow air down in.
Stuff's going to come flying out.
If you're not wearing safety glasses, well, that's on you, really.
Safety first.
Number one concern here at 1A Auto.
So I'm just going to go down the line.
I'm going to give it a little blast.
Got a little bit out of that one.
There we are.
Now we're clear to use our tool.
You can get this down at 1A Auto.
It's a specialty tool, little bit of a swivel to it.
I'm going to put it in.
I'm going to be turning these to the left, counterclockwise to break them free.
All right.
Feels like it's ready to come up and there's our spark plug.
Now if you can take a look at it, you want to make sure that you don't see any buildup.
A lot of times, you'll see white chunks built up on here.
That's unburnt carbon or even black.
You don't want any of that.
If it's not clean or even if this is peened in or broken off, you want to replace it.
It's very simple to replace.
You can look.
You can make sure that the gasket's good.
I mean, that doesn't really matter because we're going to be replacing this anyway.
So at this point, you can go ahead and replace it with another quality part.
Now that we have all four of them out and we completed our inspection of all the spark
plugs, made sure that none of them were broken apart or anything, there might be nothing
inside this cylinder, we should be fine to put in our new quality part.
We're going to do the same install.
You don't need to do with a ratchet to start it.
You want to go by hand.
You want to feel it.
We can start all four of them if you want.
Just get them all in there hand tight and then we'll go ahead and torque them down.
Getting close here.
At least it felt like we were.
There we are.
We got these hand tight and now we'll go ahead and torque them down.
We got our torque wrench set up to 14 foot pounds.
We're going to go ahead and start on one side and work our way across.
I'm going to gently put this onto our spark plug.
We're just going to go to 14 or as close as we can to that.
You don't want to go more and you don't want to go less.
You go less, it won't be seated right.
It could blow out on you.
You go more, it could strip out the spark plus into the head.
There we are.
We're going to do that for all four.
Now it's time to reinstall our coils.
So what I like to specify is to make sure that we've already checked to make sure that
the seals are good and I want to make sure that I put a little bit of dielectric grease.
I'm going to come along the outside right along here, little bit along the inside.
That what a spark plug's going to go into and then I'm going to come along the top right
along here.
What this is going to do, it's going to make sure that moisture doesn't get past.
Any debris will get caught on the dielectric and also so the next time that you go to do
the spark plugs on this or a tune up of any sort, it'll come off nice and easy.
We're going to do the same process for all four coils and then we're going to go ahead
and install it.
So I'll just show you that.
You can see that there's a little lip right here so the coil knows where to sit.
It can't turn any further.
We can grab one of our bolts.
They're all the same.
So you don't have to worry about which one's which.
We're going to go ahead and screw that in a little bit and we'll do the same process
for all four coils.
I'm going to go ahead and install the last screw, bolt, whatever you want to call it,
finger tight.
Now we're just going to go down the line.
We're going to snug them all up.
You don't need to use a long handled ratchet.
This is what I have in my hand.
So I'm just going to hold it down low.
We don't need very much torque.
We're just going to snug it just like that.
Same down the line.
Our next step would be connecting our wires to our coils.
If you wanted to, you can use a little bit of dielectric grease in here.
For this application, I'm not going to worry about it.
Just go ahead and lift it.
Listen for the click.
Going down the line.
Okay, if you happen to remove these clips, you can go ahead and put them in now.
Now using our 5 millimeter Allen head socket, we're going to go ahead and reinstall these
bolts.
As you can tell, they're all the exact same.
So first, we'll get our cover on.
We want to line up the holes, remember where they all are.
Get that settled on there.
I can see all the holes right through.
So we can start these in by hand if you'd like.
Given them a couple threads.
We don't want to tighten any of them down completely until we get all three in, at least
started and that's because this happens to be off kilter a little bit.
When you tighten these down, now you can't get the last bolt in.
So we'll just leave it nice and loose and line it up where we need.
We can go ahead and tighten these down.
We don't need to go very tight.
It's just plastic.
You can use whatever you have for a tool.
But it's a 5 millimeter head.
Nice and snug.
Snug.
Last one.
There's only three.
There we are.
Nice and secured.
Thanks for watching.
