Where is the number 3 spark plug on a 1997 ford Taurus?

The firing order for a 1997 Ford Taurus 3.0L V6 is typically 1-2-3-4-5-6. However, there's no universally consistent way to visually number the spark plugs based on their location. The location of cylinder #3 will depend on whether it's a left or right bank and which end of the engine you consider "front".

To find spark plug #3, you need to consult a repair manual specific to your 1997 Ford Taurus 3.0L V6 engine. The manual will have a diagram showing the engine and the location of each cylinder and its corresponding spark plug.

Don't rely on generic images or descriptions. Engine layouts vary slightly even within the same model year. A repair manual will give you the precise information you need to avoid any potential mistakes.
