What's up, guys?
I'm Andy from 1A Auto.
In this video, I'm going to show you how to replace the ignition coils on this 2001 BMW
325xi.
If you need this part, or other parts for your vehicle, click the link in the description
and head over to 1Aauto.com.
The battery is in the trunk.
I'm going to disconnect the negative terminal.
I'm just going to use a 10-mm wrench and loosen up this nut right here.
Then grab the connector and disconnect that, and set it aside.
All right.
We're going to take this cover off.
We have this nice light that we can see a lot better under the hood.
We sell this at 1Aauto.com.
It hooks right onto the hood.
Open this up, lift this cover.
This should slide out just like that.
Just slides forward.
Now we can grab this cabin filter, slide it out.
Take a straight-blade screwdriver, or pocket screwdriver, or even a pick, and we're going
to take this cover right off here.
Just get under there, snap this off.
Just like that.
Slide that out of the way.
We can pull these wires down.
Just like that.
There's four screws right here, one, two, three, four.
I'm going to use a T30 socket, extension and a ratchet to take these out.
They should stay with the cover, so they're not going to fall out.
With all those loose, I can grab this.
Just slide it out.
I might have to just loosen this by hand a little bit.
And pull this off, set it aside.
So, there should be two covers over here and right here.
You just take a pocket screwdriver and get underneath there and pop those off.
Then there is a bolt in there and there.
We're going to use a 10-mm socket, extension and a ratchet to take those bolts out.
I'm just going to use a magnet to grab the bolt, and just grab this cover, pull it off.
We can grab the oil cap, fill cap.
Take a pocket screwdriver right here and there's also a cover right here.
Just take these covers off.
I'm going to take a 10-mm socket, extension and a ratchet, and there's a nut here and
also under that cover.
Take those out.
All right, I'll pull that nut out.
We can grab this cover and slide it off.
So, this front coil has a ground strap on it, and also that back coil has a ground strap,
so you want to keep that in mind before you take it apart.
I'm going to take a 10-mm socket, extension and ratchet and take these two bolts out.
Set that ground strap aside.
You can slide this retainer up.
There's like a lock on this.
As you slide this up, you should be able to disconnect the connector and then wiggle the
coil back and forth and pull it out.
Here's the old coil.
Here's the new coil from 1Aauto.com.
The shape is the same, the boot is the same length, the connector is the same, and it
has the same lock on it.
Get yours at 1Aauto.com and you can do it yourself.
Take the new coil, slide this on here.
You could actually put some dielectric grease in there if you wanted to.
It's a good idea.
Then slide this into position.
We'll connect the connector and lock it down.
Then this one has the ground, same as the last one.
Take the two bolts.
For that forward one, put it through the ground strap.
Take a 10-mm socket, extension and ratchet and we'll snug these down.
Snug.
Then we can do the same with the other ones.
Then we'll put this cover back on.
Slide it back into position, put the cap back on.
If you wanted to, you could have left the cap on once you take the cover off, so you
don't drop anything in there.
Put the nut back on.
Put this nut back on.
Get those started.
I'll use a 10-mm socket, extension and ratchet and tighten these down.
Snug those down.
Not too tight.
It is a plastic that you're holding down.
On this cover, we have these two caps.
Get those lines up, and press those in.
Now, we'll reinstall this cover.
Slide it under the wires.
There's a couple of clips underneath here that have to slide onto this rail.
Let's see.
There we go.
All right.
Make sure those clips are slide in position and take the bolts, get the bolts started.
Take a 10-mm socket, extension and a ratchet and we'll tighten these down just snug.
It is plastic, not too tight.
There should be two caps that go over here.
This vehicle doesn't have them.
They're missing, so I'm not going to put those in, but make sure you reinstall those caps.
All right, and then we want to install this.
Just get this lined up and get these screws started.
I'm going to take a T-30 socket, extension and a ratchet and tighten these up.
Now reinstall these wires in this cover right here.
Just like that.
Take this cover, line it up.
That's good.
Take the filter.
We're going to slide it in with curve side towards the vehicle, so the bowed side more
towards out of the vehicle.
Just slide that in position like that.
We'll take this cover.
It's going to just slide in underneath this weather stripping.
Just push it in.
Get these lock tabs to line up and lock them down.
They're spring loaded.
The last one, and you're good to go.
Reconnect the battery.
Put the negative terminal on.
Take a 10-mm wrench and just tighten up this nut and just snug it up.
Make sure it's tight, it doesn't wiggle loose, and you're good to go.
Thanks for watching.
