Chrysler 300 (2005-2023) firing order — diagram & guide
Back in 2005, Chrysler announced a full-size luxury sedan that was supposed to make a perfect blend of luxury and performance. After a long production run, the model is scheduled to end production in 2024, so it’s a perfect time to look back at the Chrysler 300 (2005-2023) firing order.
Our team aims to provide all the proud owners of the Chrysler 300 regardless of the engine type, so we’ll cover the firing sequences for all of them. We’ll also take a look at the cylinder arrangement for all the engine types from the V6 Chrysler 300, all the way to the HEMI V8s, so let’s take a look.

First-generation Chrysler 300 (2005-2010) firing order
The first-gen Chrysler 300 featured a wide variety of engine options including a lot of V6 and V8 engines. The convenient thing is that all the petrol V6s had the same firing order, and the HEMI V8s also featured a common firing pattern, so let’s take a look.
Chrysler 300 2.7L firing order
The 2.7-liter engine was used as a base option for the first-gen Chrysler 300 and it was a commonly used engine in Europe. So, the Chrysler 300 2.7L firing order is 1-2-3-4-5-6, and this V6 is a regular longitudinal powertrain.
That means cylinders 1, 3, and 5 are arranged front to rear on the passenger’s side, while cylinders 2, 4, and 6 are located within the driver’s side bank.
Chrysler 300 3.5L firing order
The Chrysler 300 3.5L firing order is 1-2-3-4-5-6 and this engine is pretty similar to the 2.7-liter engine. The cylinder arrangement is pretty much the same, so cylinders 1, 3, and 5 are arranged front to back on the passenger’s side of the engine.
Even cylinder numbers 2, 4, and 6 are located on the opposite side of the engine, so the firing order and cylinder arrangement are the same regardless of which V6 engine your Chrysler 300 has.
Chrysler 300 5.7L firing order
As the first V8 engine used in the Chrysler 300, the 5.7-liter powertrain was the most widely used engine for this model, especially in the North American market. The Chrysler 300 5.7L firing order is 1-8-4-3-6-5-7-2, and the cylinders are divided into two banks with four cylinders each.
The cylinders 1, 3, 5, and 7 are on the driver’s side of the engine, ordered front to rear. The front-most cylinder of the opposite bank is the second cylinder, followed by cylinders 4, 6, and 8 toward the rear of the passenger’s side bank.
Chrysler 300 6.1L firing order
The 6.1-liter engine was used in an SRT version of the Chrysler 300, and this HEMI V8 also features the same firing pattern as the 5.7-liter one. For owners of this model, that means the Chrysler 300 6.1L firing order is 1-8-4-3-6-5-7-2, and the cylinder arrangement is the same as it is for the 5.7-liter engine.
Chrysler 300 3.0L diesel firing order
As an exception among six-cylinder Chrysler 300 engines, the 3.0L diesel featured a different firing pattern and cylinder layout. The Chrysler 300 3.0L diesel firing order is 1-4-2-5-3-6, while the cylinders are arranged in two cylinder banks.
However, unlike with petrol V6s, this time cylinders 1, 2, and 3 are arranged front to rear in the passenger’s side bank, while cylinders 4, 5, and 6 are ordered in the same way on the driver’s side.
Second-generation Chrysler 300 (2011-2023) firing order
Things have remained pretty much the same when it comes to engine options used in the second-gen Chrysler 300 model. Once again, drivers could choose between V6 and V8 options, with the same 5.7L HEMI V8 and 3.0-liter diesel engines being available.
Since we already discussed their firing patterns, let’s focus on the newly added options for the second-gen model.
Chrysler 300 3.6L firing order
The 3.6-liter Pentastar V6 is one of Chrysler’s most reliable engines and it was featured as the main engine option for the base Chrysler 300 model. It’s an upgraded version of the 3.5-liter engine used in the previous generation, so the Chrysler 300 3.6L firing order is 1-2-3-4-5-6.
Plus, the cylinder arrangement is the same as it was for the previously used V6, so cylinders 1, 3, and 5 are on the passenger’s side, while cylinders 2, 4, and 6 are on the driver’s side, front to rear.
Chrysler 300 6.4L firing order
The Chrysler 300 6.4L firing order is 1-8-4-3-6-5-7-2 and this HEMI V8 has been used for the latest Chrysler 300 models. Luckily, the cylinder order is also the same as for the earlier versions of Chrysler’s HEMI engines, so odd cylinder numbers are once again ordered on the driver’s side.
While cylinders 1, 3, 5, and 7 are laid out front to rear in the driver’s bank, passenger’s side cylinders are ordered 2, 4, 6, and 8 front to rear.
Our take
Knowing that the Chrysler 300 is at the end of its production run is sad for every true automotive enthusiast, but we are hoping that you’ll be able to keep yours driving smoothly for years to come.
Thanks to our guide, maintaining the engine should now be less of a problem for you, regardless of whether you have a V6 or a HEMI V8 300.
