Once you located them. Get one of the new spark plugs that are per set and try different sockets on it until you have the right one. Once you know that you will need a ratchet and a extension to fit the socket. Take off the spark plugs wires carefully then unscrew the old spark plugs. Look at them to see if they have oil, corrosion and etc on them. If they do this will give you a indication on how your engine is doing. Then put your new ones in and do not over tighten then wires back on and that is basically it.
The other posters are correct, but most of those cars are a REAL pain to change sparkplugs in. They use a transverse mounted V-6 engine, which readily makes the front three plugs quite accessible. The REAR three plugs are another story. It helps immensely to have the correct tools, along with arms made of rubber.



In some of those vehicles, you must actually disengage one or more motor mounts and pry the engine forward in order to gain access to the three rear plugs.
