Short and long extension, one 90 degree elbow, 3/8 ratchet and be prepared to bloody a couple of knuckles. On the bright side, plugs should only need changing every 100K miles.
If your car has the 2 dogbones on the front of the engine all you have to do is loosen the nut where they swivel on each one and you then pull the engine forward to get to the back plugs.
front plugs are easy to get at! the back ones are a little tricky,I found the best way to remove back plugs on a 3.1,is to remove coil pack,it has 3 bolts to hold it on.now you can get to back plugs easier!!#1 plug is under alternater.
to change the plugs, remove the air filter element - lean over engine to back and unscrew plugs and replace same with new ones
I suspect you have V6. If it is the case, you will have to remove intake manifold. There is no other way to replace it.
Loosen the 2 dog bones on the front of the engine and pull the motor forward to get to the back plugs.
The back package tray will have to come out to get to the bolts that hold them in.
The spark plugs are on the front and back of a V6 (back ones are tough to get to) L4 right in front. Turn the engine off and take off the spark wires unscrew the plugs

Spark plugs are cheap so, when you pull them to read them, don't put them back in. Replace them with new. To read the plugs, you need to compare them to the pictures at the link. They will tell you about your engine's health. Fouled plugs are not the problem, they are the symptom.
Ok, the screws are rubber or plastic and when you go to unscrew they just spin or strip. So get needle nose pliers and pull them straight out ! Replace the bulbs and use screws as plugs and plugs them back in. yea Knowing is half of the battle.
Get a big hammer and start beating on the car from the front to the back and keep repeating.

When the engine is removed from the engine compartment, and detached from the transmission, there are freeze plugs on the back side of the engine. You may be able to just disconnect the engine from the transmission, and loosen the motor mounts and lift the engine partially away to replace the freeze plugs.
you can get to some from the front and the ones in the back you can get to through the wheel wells
Remove the top motor mounts and tip the engine foreward
on the back side, I find easier to replace from under the car as there is more space for your arm, and less likely to break your new plugs
you need to take off the door panel then when it is off you will be able to pop out the switch and unplug it then plug in your new switch pop it back into the door replace the door panel and that's it
If it's a V-6, the front plugs are easy to replace but you'll need a universal joint to get at the back plugs. You practically have to climb on top of the engine to get at it. It can be done but it's a royal pain. You have to use sense of touch-only.
