* Access: You'll likely need to remove the plastic engine cover (if equipped) to get a clear view.
* Location: The spark plugs are nestled in the cylinder heads, one per cylinder (6 total). The spark plug wires connect to the spark plugs and route to the ignition coil packs which are typically mounted on top of or very near the valve covers.
Important Note: Without a diagram specific to your vehicle's engine, I can't give you precise "cylinder 1 is here, cylinder 2 is there" instructions. Incorrectly identifying cylinders can lead to engine misfires or damage. Use a repair manual specific to your 2003 Saturn Vue V6 3.0L. These manuals have diagrams showing the precise location of each cylinder, spark plug, and wire. You can find these manuals online (e.g., Haynes, Chilton) or at auto parts stores.
Attempting this work without the correct information and tools could lead to injury or damage.
