First-generation GMC Acadia (2007-2016) firing order
The first-gen Acadia model used a single engine option and that was the 3.6-liter V6 engine. It’s also the only six-cylinder engine used in the Acadia so far, and we’ll focus on that engine first in terms of its cylinder firing order and configuration.
GMC Acadia 3.6L firing order
The GMC Acadia 3.6L firing order is 1-2-3-4-5-6 and this firing sequence comes standard for GMC’s V6 engines. However, what’s not so regular about the engine is its cylinder placement, considering that this engine is a transverse six-cylinder.
That means it has two cylinder banks in terms of a top bank and the bottom cylinder bank. Within the first cylinder bank, cylinders are laid out in order 1, 3, and 5 from left to right, while the bottom bank features cylinders 2, 4, and 6 in the same order from left to right.
Second-generation GMC Acadia (2017-2023) firing order
Along with the initial V6 engine, the second-gen Acadia model received a few updates in the form of four-cylinder petrol engines. Both the 2.0-liter turbo engine and the 2.5-liter engine were added to the lineup, so we’ll focus on these next.
GMC Acadia 2.0L turbo firing order
Unlike the previously mentioned engine, the GMC 2.0-liter turbo is a four-cylinder. So, the GMC Acadia 2.0L turbo firing order is 1-3-4-2 and this firing order also goes for the rest of the four-cylinder engines from the manufacturer.
In terms of the cylinder positions, you can see the order from the first one on the left side, all the way to the fourth one on the right side of the engine in a straight line.
GMC Acadia 2.5L firing order
The GMC Acadia 2.5L firing order is 1-3-4-2 as well and this engine has the same cylinder configuration as the 2.0-liter turbo engine. So, cylinders are laid out in a straight order from 1 to 4 looking at the engine from left to right.
