What is the best way to replace the spark plugs in a 2004 chevy malibu classic? this will be my first time doing this and all manuals advised thus far have proven to be quite vague, and less than helpful. any information you may be able to pass along is much appreciated. thanks!
Search for the engine model ECOTec 2.2 rather then Malibu. It is very easy to replace the plugs, they are DEEP inside the engine so you will need a 6" socket extension for the spark plug socket. Needle nose pliers were required to retrieve the socket on the first plug. Don't push down hard on the plug, just enough to engage the nut. Full screen photo sequence is available at:

The only thing i will recomend is to make sure the engine is complety cold before doing it, because more of this cars come with aluminum heads and if not cold before doing it might damage spark plug thread, i can't remebre very well the easiest way to replace them, but if it is a v-6 motor will be easier by removing the two top engine mounts on top of radiator and the gently lift transmission by rear side of car and this will give you more clearance on the rear plugs, and if plug wires are hard to remove tunr it rt to left and then puul them of, if they brake don;t try to fix them just replace it.
