Hi, I’m Mike from 1A Auto. We’ve been selling auto parts for over 30 years!
Open the hood. We have to pull the release inside the car. It's just inside right around your left knee on the driver's side. Need to release the secondary, or safety release. Just kind of feel around for it. This one is right here. Squeeze up.
Going to remove these two top nuts that hold on the appearance cover. They are 10 millimeter, so I'm using a 10 millimeter socket ratchet and extension. Should just thread of real easily. So there's our appearance cover, it's got some foam inside. That's just for noise, just keeps the noise down from the valve train.
Here are your four coil packs. One for each cylinder. They're held in to the valve cover with a 10 millimeter bolt, one for each. Push down on the lock and remove the connector. These can be brittle, sometimes they break. The lock does. This procedure will be the same for the other three. Use a ratchet, extension, and 10 millimeter socket to remove this 10 millimeter bolt. Put this bolt aside.
Now we need to remove the coil. Might have to wiggle it because there is a seal in here and just break it free. Once it's free, it should come right up. There's our coil pack.
It does have some oil on it because our valves cover gasket has been leaking. Reinstall the coil. Line up the opening with the amounting bolt hole. Move the harness out of the way so it doesn't get pinched. Push right over the spark plug and reinstall the bolt. Once it gets tight I'm just going to stop. Put the connector back in.
Now I can reinstall the plastic engine cover. I wiped it down with a rag and cleaned some of the dirt off of it. Make it look a little nicer. Get lined up over those studs. Sit right down reinstall the nuts. Actually just do these hand tight. They don't need to be super tight. Job is complete.
