Where is the number 2 cylinder on a 4.0l ford engine?

On a 4.0L Ford engine (typically referring to the Cologne V6 or the SOHC inline-6), the cylinder numbering is usually done from the timing chain/belt end of the engine. Therefore, cylinder #2 is the second cylinder from the timing chain/belt end. It's important to note that the exact arrangement may vary slightly depending on the specific engine orientation within the vehicle, but that's the general rule. If you have access to a diagram for your specific year and model, consult that diagram for absolute certainty.
