The 2012 Kia Soul uses an inline-four engine, with cylinders arranged in a straight line. The cylinder numbering from the front of the engine toward the rear is 1-2-3-4, and the standard firing order for these engines is 1-3-4-2.
The following sections break down the cylinder numbering and firing order, which are important for maintenance tasks such as spark plug changes, ignition coil replacement, and timing-related work. The Soul was offered with two inline-four engines that share the same basic cylinder layout, though exact components can vary by model and trim.
Cylinder numbering order
Before listing the cylinder numbers, here is how they are arranged along the engine block in the 2012 Soul’s inline-four configuration.
- Front-most cylinder: 1
- Second from the front: 2
- Third from the front: 3
- Rear-most cylinder: 4
Understanding the front-to-back numbering helps locate spark plugs, fuel injectors, and valve components during maintenance or repair.
Firing order
Ignition firing order describes the sequence in which the cylinders ignite. For the 2012 Kia Soul’s inline-four engines, the typical firing order is 1-3-4-2.
- Firing sequence: 1 → 3 → 4 → 2
Note that ignition wiring or coil placement is designed to support this firing order, and variations are uncommon but should be verified against the specific engine variant in your vehicle’s service manual.
Notes on engine variants
Depending on whether your Soul has the 1.6-liter or 2.0-liter inline-four, components may differ, but the cylinder order (1-2-3-4) and the standard firing order (1-3-4-2) generally remain consistent across these engines. Always consult the owner’s manual or a service manual for the exact engine you own to confirm any model-specific details.
Summary
In the 2012 Kia Soul, the inline-four engine has cylinders numbered from front to back as 1-2-3-4, and the firing order is 1-3-4-2. These conventions apply to the main engine options for that model year, though exact components may vary by variant. When performing maintenance, use these references to locate plugs, coils, and timing components, and verify with the official manual for your specific vehicle.
