Angry Sparkplug replacement

2001 Pontiac Aztek, 3.4L engine, FWD. Can anyone tell me the easiest way to get to the plugs on the back side (firewall side) of the engine. I tried disconnnecting the front engine struts, and rolling the engine over, however there is still not enough room to access the plugs. Any ideas?

Special tools and engine rotation isn't necessary. Put the front of the Aztek on ramps then set the emergency brake and chock the rear tires. You will be working under the car. Get a 3/8 inch ratchet with a long extension, a swivel, a spark plug socket and a standard deep well socket. Use the spark plug socket for removing the old plugs and the standard socket for installing the new plugs. The spark plug socket has rubber inside that holds tightly to the plug and this will make it difficult to remove from the new plug once tightened due to the limited working space. Progress will be slow and you will rely on feel. Positioning yourself and maintaining position will be somewhat difficult but the work itself is easy.
