Where is the number 3 cylinder on a 03 expedition?
On a 2003 Ford Expedition (which has a V8 engine, not a 3-cylinder), there isn't a "number 3 cylinder" in the same way a smaller engine might have. V8 engines are arranged in a "V" shape, typically with cylinders numbered sequentially from one bank to the other. To determine the location of what might be considered a functional equivalent of cylinder 3, you'd need to consult a detailed engine diagram for the specific 2003 Expedition's 4.6L or 5.4L V8 engine. The numbering scheme will vary depending on the engine and whether it's viewed from the front or back of the vehicle.
