To understand cylinder position, you need to specify what you're looking for:
* Firing order: As mentioned above, it's 1-5-4-2-6-3-7-8. This is the sequence in which the cylinders fire.
* Cylinder location relative to the engine: This is usually described from the perspective of standing in front of the engine. Cylinder 1 is typically at the front, passenger side (right side in North America). The cylinders are numbered sequentially, moving towards the rear of the engine and then back to the front on the driver's side.
* Specific position for a maintenance task: If you're working on a specific part (e.g., spark plug, valve), you'll need a workshop manual specific to your year and model of Ford vehicle with the 5.8L engine. These manuals provide detailed diagrams and instructions showing the exact location of each cylinder for that task.
Therefore, to accurately answer your question about cylinder position, please clarify what information you require.
