Their seems NO easy way to replace the rear plugs on these G.M. 3.1 cars. BUT you can unbolt the motor mounts that are located on the front of the engine and with your pry bar between the firewall & motor pry back and stick a board or some other kind of wedge in there. This will gain you around 4 more inches of room and you can use a ratchet with a swivel to get the plugs out!!

How do you change spark plugs in 2002 Chevy Malibu 6 cylinder3.1?

I have a 2000 Malibu 3.1,and i found the best way to change the plugs, in front you have plenty of room, in back if you take the 3 bolts on coil plate out and disconnect wiring. the back plugs are easier to get to!! remove coils and plate, on lumina 3.1 you can tilt engine forward,but on Malibu 3.1 you cant move engine forward!! firing order is ---1-2-3-4-5-6-----135 in back 246 in front.
