Which is number 1 spark plug on 2002 ford windstar?
The firing order for a 2002 Ford Windstar (assuming the 3.8L V6 engine) is typically 1-6-5-4-3-2. Therefore, cylinder #1 is at the front passenger side of the engine. However, visually identifying the #1 spark plug requires locating the #1 cylinder and then finding its corresponding plug wire. Refer to a repair manual or online diagrams specific to the 3.8L V6 in your 2002 Windstar for precise visual location. The diagrams will show the cylinder arrangement and the plug wire routing.
