Chrysler Pacifica (2004-2023) firing order — diagram & guide
Chrysler Pacifica has been one of the most interesting nameplates in the brand’s history since it was associated with several different vehicle types. After all the concept versions, the crossover Pacifica came out in 2004 and the minivan version went into production in 2016.
Both of these versions featured some of Chrysler’s signature engines like the Pentastar V6, but sometimes drivers were required to conduct engine checkups. For those of you who enjoy doing the upkeep themselves, Chrysler Pacifica (2004-2023) firing order can be a great asset. We’ll tell you all about it in this guide, as well as how you can apply it to diagnose misfires and even oil leaks for your particular engine.

First-generation Chrysler Pacifica (2004-2008) firing order
The first generation of the Pacifica was sold as a crossover-class vehicle and it featured some specific transverse V6 engines from Chrysler. The firing order for these is the same for all the engines so that makes things a lot easier for drivers, but let’s take a closer look.
Chrysler Pacifica 3.5L firing order
The 3.5-liter V6 is the only V6 engine used in the Pacifica that’s not placed transversely in the engine bay. So, the Chrysler Pacifica 3.5L firing order is 1-2-3-4-5-6 and the engine is a longitudinal V6 which means it has a driver’s side and a passenger’s side bank.
The driver’s side bank includes cylinders 2, 4, and 6, while the opposite side bank includes cylinders 1, 3, and 5.
Chrysler Pacifica 3.8L firing order
Just like for the 3.5L engine, the Chrysler Pacifica 3.8L firing order is 1-2-3-4-5-6, but the cylinder configuration of this one isn’t the same. This one is a transverse engine, which means the cylinders are arranged in the order 1, 3, and 5 from left to right in the upper cylinder bank.
There’s another bank right below it, and this one includes cylinders 2, 4, and 6 also arranged from left to right.
Chrysler Pacifica 4.0L firing order
Chrysler used another transverse V6 engine in the first-gen Pacifica and that one was the 4.0-liter engine. The Chrysler Pacifica 4.0L firing order is 1-2-3-4-5-6 as well, so you can see that it’s a common firing pattern that all the Chrysler’s V6s share.
Plus, the transverse placement means that the cylinder order matches one of the 3.8-liter Pacifica. So, the odd cylinder numbers from 1, 3, 5 are all within the upper cylinder bank, with the even cylinder numbers from 2, 4, 6 being right below them.
Second-generation Chrysler Pacifica (2016-present) firing order
Unlike the first generation, the second-gen Pacifica was a different model as it was a minivan with just one engine option available. It’s one of the most reliable Chrysler engines up to date, so let’s take a look at the firing order of the Pentastar V6.
Chrysler Pacifica 3.6L firing order
The Chrysler Pacifica 3.6L firing order is 1-2-3-4-5-6 once again and this engine is a longitudinal V6. That means it has two cylinder banks with three cylinders each, but this time they are located on the driver’s side and the passenger’s side.
With that in mind, the driver’s side cylinders are ordered 2, 4, and 6 front to rear, while cylinders 1, 3, and 5 are ordered front to rear on the passenger’s side.
Now that you’ve gone through this guide, you should have an easier time keeping the engine running smoothly in your Pacifica. Whether you have a crossover or a minivan version, the firing order matches for all the engine options, so at least you should have an easier time figuring things out and preventing misfires from now on.
