Where is number five spark plug on a 2000 Taurus 3.0 L V6 Duratec engine?

On a 2000 Ford Taurus 3.0L Duratec V6, the spark plug numbering isn't always consistent across diagrams and sources. However, the general firing order is crucial to figuring it out. The firing order is usually 1-2-3-4-5-6. It's always best to consult a diagram specific to your year and engine.

You'll find that diagram in a few places:

* Your Owner's Manual: This is the best place to start.

* Repair Manual (Haynes, Chilton, etc.): These provide detailed diagrams and often show spark plug locations.

* Online Resources: Search for "2000 Ford Taurus 3.0L Duratec spark plug location diagram". Be sure the image matches your specific engine.

Instead of trying to guess based on a generalized description, I strongly urge you to find a diagram. Misplacing a spark plug can lead to damage. Once you have the diagram, you'll easily locate #5. The cylinder locations are typically relative to the orientation of the engine in the bay.
