The firing order is 1-6-5-4-3-2.
For this model, understanding the cylinder layout and ignition wiring is essential for maintenance, diagnostics, and timing tasks. The following explains how the cylinders are arranged and how the firing sequence applies to spark plug and coil connections.
Cylinder layout and firing sequence
On the 3.7L PowerTech V6, the engine is arranged in two banks. The firing sequence follows the 1-6-5-4-3-2 order, meaning the spark events occur in that sequence around the engine. This order is important when replacing spark plugs, coils, or when diagnosing misfires.
To help apply this in practice, note the following:
- Cylinder numbering: The two banks are numbered 1-3 on one bank and 4-6 on the opposite bank. The exact orientation (which side is 1, etc.) is shown in your service manual or on the engine’s label. Use those references when mapping coils to cylinders.
- Firing order: 1-6-5-4-3-2. This is the sequence in which the cylinders fire during each engine cycle.
- Ignition hardware: Depending on the model year, the 3.7L may use coil-on-plug ignition with six independent coils or a coil harness arrangement. Ensure each coil is connected to the correct cylinder as per the diagram in the service manual.
Verifying the firing order helps ensure proper timing, efficient combustion, and accurate diagnostic work for misfires or spark plug replacement.
Related verification and notes
If you’re unsure, check the vehicle’s service manual, the under-hood engine label, or a trusted repair database. Ignition coil-to-cylinder mapping and cylinder numbering are confirmed in factory documentation and may vary for aftermarket configurations.
