Hello,

I am trying to find a "How To" on changing the spark plugs. I've read where people say remove the 4 allen bolts and pop off the cover. I have stars and way more than 4. If I am in the right area.

I just purchased new Iridium plugs.

Thanks!

You pull off the center cover on the valve cover, it's the piece that says ecotec on it. Under that you will fine the coil pack, it has the wiring harness plugged into the drivers side of it. It's held on with those screws/bolts. You take them off and pull straight up on the coil. There are four "tubes" on it that go down to the spark plugs.

Look in the four holes and you'll see the tops of the plugs.

Reassemble the same way in opposite order.
