5.7 Hemi and 6.4 Hemi firing order and cylinder numbers
The Chrysler 5.7 and 6.4 Hemi V8 fires 1-8-4-3-6-5-7-2. Cylinder 1 is the front cylinder on the driver side (bank 1, left bank).
Drag to turn the engine, scroll or pinch to zoom. Orange = the cylinder firing now; the numbers on the coils are cylinder numbers. Driver and passenger sides are for left-hand-drive vehicles.
Firing order diagram
Where each cylinder is
| Cylinder | Misfire code | Location | Place in firing order |
|---|---|---|---|
| 1 | P0301 | The front cylinder on the driver side (bank 1, left bank) | 1st |
| 2 | P0302 | The front cylinder on the passenger side (bank 2, right bank) | 8th |
| 3 | P0303 | The second cylinder from the front on the driver side (bank 1, left bank) | 4th |
| 4 | P0304 | The second cylinder from the front on the passenger side (bank 2, right bank) | 3rd |
| 5 | P0305 | The third cylinder from the front on the driver side (bank 1, left bank) | 6th |
| 6 | P0306 | The third cylinder from the front on the passenger side (bank 2, right bank) | 5th |
| 7 | P0307 | The rear cylinder on the driver side (bank 1, left bank) | 7th |
| 8 | P0308 | The rear cylinder on the passenger side (bank 2, right bank) | 2nd |
Bank 1 is always the bank that contains cylinder 1, so for this engine bank 1 is the left bank with cylinders 1-3-5-7; bank 2 is the right bank with cylinders 2-4-6-8. Oxygen-sensor, camshaft and catalyst codes that name bank 1 or bank 2 use the same split.
Coils, plugs and wires
- Eight coil connectors, four on each side, one per cylinder. Connect each coil to its own cylinder; a swapped pair causes misfires.
How to find a cylinder on this engine
- Find the front of the engine: the end with the drive belt and pulleys.
- Find bank 1, the left bank that holds cylinder 1. On this engine it is the driver side.
- Count from the belt end. Cylinders 1-3-5-7 run along bank 1 and 2-4-6-8 along bank 2, each starting at the belt end.
- Match the code: P0301 is cylinder 1, P0302 cylinder 2, and so on. P0300 means a random or multiple misfire and does not name a cylinder.

Questions
What is the Chrysler 5.7 and 6.4 Hemi firing order?
1-8-4-3-6-5-7-2.
Which side is cylinder 1 on?
Cylinder 1 is the front cylinder on the driver side (bank 1, left bank).
Where is cylinder 4 (code P0304)?
Cylinder 4 is the second cylinder from the front on the passenger side (bank 2, right bank).
Which bank is bank 1?
The bank with cylinder 1: the left bank, cylinders 1-3-5-7.
Is the 6.4 Hemi firing order the same as the 5.7?
Yes. Chrysler's service manual gives 1-8-4-3-6-5-7-2 for both the 5.7 and the 6.4, with the same cylinder numbering.
Is the Hemi firing order the same as a Chevy 350?
The sequence is the same, 1-8-4-3-6-5-7-2, and so is the layout: odd cylinders on the driver side. The engines are otherwise unrelated.
