SOURCE: location of spark plugs on a 2005 cavalier?

You have to remove the black piece in the center on top of the engine. This is your coil pack. Unbolt and disconnect it, pull it up. Underneath the coil pack you'll see 4 spark plug boots that extend from it, down into the head. It's best to have a spark plug socket with a long extension but do your initial install of the plugs by starting the plugs on the end of a piece of tubing or fuel line. Do not drop anything in the plug holes! Easy to do because they are facing up.
