I have an 03 rendezvous and I am puzzled on the best way to remove the rear spark plugs. Any help? It looks like you need skinny and long arms to get up in there.

I'm unfamiliar with your exact car, but the "Trick" in the attached link may work or you may figure out another approach:

Keep in mind U-joints for your extension bars and sockets, as you size up the problem. Look at what you can easily remove to improve access. Only use the same ACDelco plugs that came in the vehicle.

Also, consider buying a GearWrench (#80546) magnetized extended 5/8" spark plug socket, with swivel. It eliminates the struggle of changing spark plugs. The magnetized core holds the spark plug in place and the extra long reach makes it easier to access tight spaces. It has a one-piece design, so the socket can't detach from the extension bar.
