Pop on the engine cover
We have to pop off this cover that's on top the engine. That just pops up. There's two points where it pops onto. So you just kind of get them and work them out straight from the back. Just like that. You can see here, this is where it pops on here and here and then these two tabs slide into the back. We're going to set this aside so it doesn't get broken. With our engine cover removed, you can now see the eight ignition coils on this engine. We've got four on each side. There's one, two, three, four, this is on the driver's side. We'll go over to the passenger's side. We've got one, two, three, four and the process to remove and install them is going to be the same for both sides.
This side you might have to move some of these hoses out of the way so you can get to them. But in general it should be pretty straight forward and we're going to show you that on the driver's side of the car. We're going to start by unplugging the coil. So we're going to lift up that lock, pull it out. Take my 10 millimeter socket ratchet with an extension on it, break these free. Before I take it off completely, this is our spark plug down here and the wire, I'm going to pull the wire off. Don't pull the wire, pull it by the boot. If this seems like it's stuck, you can take a small flat bladed screwdriver or if you've got a pick then just sort of work around the rubber to try to loosen it.
Go back to our ratchet, these are pretty loose so I'm just going to use the socket with my fingertips. Grab that bolt and the next bolts. We'll hold this with my other hand so it doesn't fall and we can remove the coil pack.
Here's our old coil pack from the vehicle and our new coil pack from 1AAuto.com. You can see the connectors are the same, it's got these nice metal inserts in the bolt holes. Same setup for the spark plug wire. This'll fit perfectly and perform great. Take our new coil place it on the bracket, it's loose, don't want it to fall. Our bolts, get them started with my fingers.
10 millimeter socket, ratchet extension just tighten these from the wrist, when they start to feel tight I'm going to stop. Going to reconnect our electrical connector at the top. Should push it in so it locks. Take our spark plug wire put it back in. That will click on, that's tight. And our new coil is installed. Okay, so now we're going to put this engine cover back on. So you've got these two little pins here and there's two little clips in the back. But this needs to slide up and into and then over these to lock it down. So it's easier to slide it to the back and get these hooked and then push it down onto these. It's got a little bit of a curve here, there's some heater hose lines on the other side that they need to go over it like this. So you basically just start it and then just slide it down and you can almost see it as it hits those hooks and then you push it over those pins and down and it's on.

First thing you're gonna do is disconnect the spark plug wire from the spark plug. Just grab ahold of it. Give it a twist, and pull it. Disconnect from the coil the same way, twist, and pull. You're gonna keep this heat shield. Just pull it. Set it aside. Two mounting bolts mount the actual coil to the bracket. You have one connector. So, you're gonna take that tab. Lift that tab out. Pull the connector out. 10 millimeter socket. Lift the coil out.
So, to reinstall, just reverse procedure. Line up the bolts. Torque the two mounting bolts to 89 inch-pounds. Double-check. Now, you're gonna reinstall the connector. Line it up. Push it down until you hear it click. Tab's locked. Twist on the new coil wire, spark plug wire, it comes pre-siliconed. Slide your old heat shield over it right to the bottom. I like to put it right on the spark plug until it clicks in. Hear it? And line up the angle to the coil. Now, just repeat the procedure to the other seven cylinders.

I would like to say thank you. I rarely order anything on line. Your web site was pretty easy to navigate other than being a little unclear aboutmy exact needs on my oxygen sensors. I ordered the wrong ones. Your customer service department was easy to work with and fixed my problem with no issues. Thanks
So far so good.
