Ford 3.7L (227 cu in) firing order — what is it?
A deep exploration into the rhythms of the Ford 3.7L firing order.
Over the years, Ford had quite a few base V6 engines that went into several of their passenger vehicles. After the 4.2-liter Essex and the 3.0-liter Duratec, the 3.7-liter V6 made its debut in 2009. Ever since then, it made a base engine option for the Mustang, so the information on its firing sequence is always welcome.
Well, that is if you can find a worthy source of the Ford 3.7L (227 cu in) firing order, so we wanted to help you cut the wait. Our team will be glad to assist you on the way of figuring out the firing order, cylinder numbering, and other relevant features to help you keep the engine running properly.
Ford 3.7L Duratec firing order
Let’s jump straight into it – the Ford 3.7L Duratec firing order is 1-4-2-5-3-6 regardless of the version of this engine. We say this because there’s a later Ti-VCT version of the same engine which is used from 2011 and it includes variable cam timing.
This means that for that version of the Duratec V6 uses a variable cam system instead of having it fixed, so the fuel efficiency and power supply can be optimized depending on the driving conditions.
The thing is – most drivers are confused by the Ti-VCT and the regular iVCT versions of the engine, so now you can rest assured that the firing order is always the same.
Ford 3.7L cylinder diagram
The order of cylinders goes hand in hand with the firing sequence if you wish to combine the two for easier working on the engine. So, the 3.7L V6 has two cylinder banks – bank 1 on the passenger’s side, and bank 2 on the driver’s side.
The first bank includes cylinders 1, 2, and 3 in that order from front to rear, while bank 2 has cylinders 4, 5, and 6 in the same order.
So, if you happen to have a bad sensor or other similar issues, you’ll know that the first cylinder is the one on the passenger’s side closest to the radiator.
Ford 3.7L vehicle applications
Well, all that’s left for us to round-up this guide is to give you an idea of all the vehicle models that use this engine:
- 2011-2014 Ford F-150
- 2014-2017 Ford Mustang
- Ford Transit
Besides Ford vehicles, the engine has also been used in a few Lincoln cars like the MKT, MKS, and the MKZ.
Well, that settles it for the guide on the 3.7L Ford’s firing order. We hope to have helped drivers that have this Duratec V6 under the hood, so make sure to use our guide and the cylinder numbering mentioned when checking the engine.
Also, make sure to differentiate between this engine and previous 3.8-liter V6 used in older Ford vehicles.
