Therefore, cylinder 1 is always the frontmost cylinder on the driver's side. The cylinders are then numbered consecutively, moving to the rear of the engine on the driver's side, and then continuing from the front on the passenger's side to the rear.
For example, a Dodge V8 would have cylinder 1 on the driver's side front, cylinder 2 behind it, cylinder 3 on the passenger's side front, cylinder 4 behind it and so on.
To know the *exact* numbering for a *specific* Dodge engine, you need to consult the engine's specifications. The best source is usually the owner's manual or a repair manual specific to the year, make, and model of your Dodge vehicle. The information might also be on an engine sticker, though this is less reliable.
