The process is time consuming...
The intake manifold has to be taken off and the gaskets replaced due to the spark plugs being under the manifold.
It would be best to take it to your dealer.

∙ 17y agoThe front are easy, so you must want to know about the back. Remove the coil back(mounted on back of motor) once you get it out of the way the back plugs are there just in front. There are 4 10mm nuts that hold it inplace, you will have to remove the two wire plugs and all the plug wires the should all have the plug numbers stamped on each wire,and the coil are all labeled also just make suer you get them back on correctly. that is about it.Also you will need a 5/8 spark plug socket that grips the plug in ordor to lift the plug in and out of the deep hole in valve cover.Also the cruze controll should be removed for easyer acc, yust tow 10mmm bolts. Good Luck, hope this helps,Ben Parker, San Jose, Ca

∙ 16y agoif it is v6 then it is a little hard to see but are in the same location as they are on most v6 motors if it is a 4 cylc then follow the wires and feel for them once you find them try putting the 5/8 spark plug socket on by hand then try to attach the wratchet usually that helps.

Where are the spark plugs on 2003 Cadillac Seville?
I don't know when Cadillac started doing this, but they eliminated the coil packs and have since been using coil on spark plug coils. They are directly over the plugs on the engine. You have to remove 4 or 5 bolts to access them.
