Here's the general concept of how cylinders are numbered:
* V-shaped design: V8 engines have two banks of cylinders, usually arranged in a "V" shape.
* Numbering: The cylinders are numbered from front to back on each bank. The front of the engine is typically where the timing cover is located.
General Firing Order:
Most 5.4L Triton engines use the following firing order:
1. Cylinder 1 (Front of the driver's side bank)
2. Cylinder 5
3. Cylinder 4
4. Cylinder 2 (Rear of the driver's side bank)
5. Cylinder 6 (Front of the passenger side bank)
6. Cylinder 3
7. Cylinder 8
8. Cylinder 7 (Rear of the passenger side bank)
Important Note: To ensure you're working with the correct information, you should always refer to the specific owner's manual for your model year vehicle.
Finding Cylinders 2 and 6:
* Cylinder 2 is located at the back of the driver's side bank of cylinders.
* Cylinder 6 is located at the front of the passenger side bank of cylinders.
