To find the #1 cylinder, you must consult the engine's specific firing order diagram, typically found:
* In the owner's manual: This is your best resource.
* On a sticker: Some engines have a sticker on the engine block or valve cover detailing the firing order.
* Online: Search for "[Engine Year] [Make] [Model] 4.6L V8 firing order" – many resources are available.
Once you have the firing order, you can locate #1. Remember that V8s typically number cylinders from one side of the engine, then the other.
