Ford 2.7L (164.4 cu in) firing order — what is it?
Fueling passion and precision: The Ford 2.7L firing order explained.
As a base option for some of the common models like the F-150 and Edge, Ford introduced a new turbo V6 engine in 2015. Ever since, it remained one of the commonly used options, but there are quite a few EcoBoost variations out there.
So, it’s no wonder that drivers are often wondering about the Ford 2.7L (164.4 cu in) firing order, and that’s what we are here to clarify. This guide will help you understand the firing sequence of this engine, as well as give you a few hints on the way that the cylinders are arranged within the block.
Ford 2.7L EcoBoost firing order
The Ford 2.7L EcoBoost firing order is 1-4-2-5-3-6 and it’s the same sequence that the 3.5-liter V6 uses as well. In fact, all the EcoBoost V6 engines share the firing order and that makes it easier to work on the engine regardless of its capacity.
However, the 2.7L Nano engine also shares some components and build materials with a Power Stroke diesel, which is interesting. Precisely, it has the same graphite iron material within the cylinder block, and it has an aluminum cylinder head.
In 2018, the engine was revised but it still maintained the same 1-4-2-5-3-6 firing order. The changes included some shared components with the 3.5-liter V6 EcoBoost, and a few notable mentions are lightweight cams, different turbochargers, and a port fuel injection system which differs from the original one.
Ford 2.7L EcoBoost cylinder diagram
The 2.7L EcoBoost features a standard V6 cylinder numbering system that Ford used in a few of its other engines. Precisely, it has two cylinder banks each containing three cylinders, and it goes 1 to 3 on the passenger’s side and 4 to 6 on the driver’s side.
The cylinders are arranged in order looking from the radiator towards the rear of the engine, with cylinder number 1 being the closest to the radiator fan.
The cylinder order depends on the way that the cylinders and spark plug wires are connected to the distributor, and that can also help you solve some issues with the firing order.
Ford 2.7L vehicle applications
Ever since it was introduced in 2015, the 2.7-liter engine has been used in quite a few models over the years. Ford initially placed into the F-150, but there are a few other vehicles that came with this engine, as you can see from the list below:
- Ford Edge
- Ford Edge ST
- Ford F-150
- Ford Fusion Sport
Besides Ford models, the engine was also used by a few Lincoln vehicles including the MKX and even the Continental.
As it turns out, the 2.7-liter engine has the exact same firing sequence as the larger V6 EcoBoost, and we are glad to have helped clear that up.
However, make sure to maintain this engine according to the manufacturer’s specifications, since not all the V6 EcoBoost options are built the same.
