First-generation Ford Fusion (2005-2012) firing order
The first generation of the Fusion started out in 2005 for North America and it mostly featured four-cylinder and six-cylinder Duratec engines. So, we’ll go through each one of those to give you a glimpse of what the firing orders are for your specific engine type:
Ford Fusion 2.3L firing order
As the base engine option for this model, the 2.3-liter Duratec was a four-cylinder powertrain with cylinders spreading from 1 to 4 in a straight line. If you have a Fusion with this engine, it has the cylinders spread out from left to right looking at it while standing in front of the engine.
So, the first cylinder will be the one on your left while the fourth one will be on the right, and the Ford Fusion 2.3L firing order is 1-3-4-2.
Ford Fusion 2.5L firing order
Moving on, we have yet another four-cylinder Duratec and it’s the 2.5-liter one. In this case, it’s important to note that the Ford Fusion 2.5L firing order is 1-3-4-2 since this is a four-cylinder version of the Duratec engine. We say that since there’s also a six-cylinder version and this one has a more complex firing order due to having two more cylinders.
The good thing is – identifying the cylinders of this engine is pretty easy as you can follow the example of the previous 2.3-liter one and go from 1 to 4 from left to right.
Ford Fusion 3.0L firing order
Now we advance to the more complex engine options and these are the V6 Duratec engines. The first one was a famous 3.0-liter V6 used in a few other Ford vehicles at the time. The Ford Fusion 3.0L firing order is 1-4-2-5-3-6 and the cylinders 1, 2, and 3 are on the left side if you are standing in front of the engine.
This bank can also be referred to as the passenger’s side bank while the cylinders on the opposite driver’s side are 4, 5, and 6 front to rear.
Ford Fusion 3.5L firing order
As the high-output version of the first-gen Fusion, the 3.5-liter Duratec model was equipped with a V6 engine with a higher capacity than the 3.0-liter one. Once again, the cylinders on the passenger’s side are 1, 2, and 3, while cylinders 4, 5, and 6 are on the driver’s side, front to rear.
The Ford Fusion 3.5L firing order is 1-4-2-5-3-6 so you can’t mix it up with another one as this sequence was standard for Duratec engines.
Second-generation Ford Fusion (2013-2020) firing order
Not only did the second-gen of the Fusion get freshened up in terms of interior and exterior updates, but it also got a few more engine options. The 2.5-liter Duratec was the only option that kept on with production from the first-gen model, so we’ll discuss the other few options in more detail.
Ford Fusion 1.6L firing order
As the first one in the lineup of Ford’s EcoBoost engines added as Fusion options, the 1.6-liter powertrain made the base option instead of a 2.3L Duratec. This time, the Ford Fusion 1.6L firing order is 1-3-4-2 and the cylinder configuration is 1-2-3-4 from left to right if you are looking at the engine from a mechanic’s point of view.
Ford Fusion 2.0L firing order
As a higher-output option, the 2.0-liter EcoBoost also debuted in the second-gen model of the Fusion. Still, the Ford Fusion 2.0L firing order is 1-3-4-2 which is the same firing pattern as for the 1.6-liter engine, and this shouldn’t come as a surprise to you.
These engines are based on the same block, so the cylinder configuration is also the same. That being said, you’ll find the first cylinder on the left side, while cylinders 2, 3, and 4 follow right up from left to right.
Ford Fusion 2.7L firing order
Finally, the last option we’ll discuss is the 2.7-liter EcoBoost which is a bit more capable engine used in a few of Ford’s base pickup models. You can see why it’s then considered a high-output option for a compact car such as the Fusion, and the Ford Fusion 2.7L firing order is 1-4-2-5-3-6.
The cylinder configuration is a bit different for this one since cylinders 1, 2, and 3 are on the passenger’s side front to rear, while cylinders 4, 5, and 6 are on the driver’s side.
If you own a Fusion model with this engine option under the hood, frequent checkups of the turbo and the wastegate are also required since it’s a major difference when compared to Ford’s N/A V6 engines.
