Buick Enclave (2008-2023) firing order — diagram & guide
Buick Enclave firing order: Harmonizing power and performance.
Buick as a brand may be mostly associated with models like the Grand National back in the day, but that doesn’t mean new models like the Enclave have nothing to offer. On the contrary, this crossover SUV proved to be a rather popular option on the US market and that’s largely thanks to reliable GM engines being used.
So, this guide on Buick Enclave (2008-2023) firing order should settle the dilemma that many drivers have regarding the maintenance of Enclave engines. We’ll not only give you the firing sequence but also discuss the cylinder map of the engine so you’ll know where to get started.
| ENCLAVE YEARS | ENGINE | FIRING ORDER |
|---|---|---|
| 1st Gen (2008-2017) | 3.6L V6 | 1-2-3-4-5-6 |
| 2nd Gen (2018-2023) | 3.6L V6 | 1-2-3-4-5-6 |
First-generation Buick Enclave (2008-2017) firing order
The first-generation Enclave introduced a GM V6 engine that stuck with the model up until the present day of production. It has also been the only optional engine for this crossover SUV, so we’ll dedicate the rest of this guide to elaborate on its firing sequence and how you can apply it for the benefit of engine longevity.
Buick Enclave 3.6L firing order
The Buick Enclave 3.6L firing order is 1-2-3-4-5-6 and that goes for both versions of the engine used. To be precise, we say that because Buick used the LLT V6 for the first-gen Enclave, while the second-gen model got an updated LFY V6 engine.
Either way, both were based on the same engine block, so their cylinder arrangement also matches. If you own an Enclave with this engine, the first cylinder will be the upper-left cylinder when looking at the engine from a mechanic’s perspective. That’s the case due to a transverse engine placement which means that the first cylinder is followed by cylinders number 3 and 5 toward the right end of this bank.
The lower-bank cylinders are numbered 2, 4, and 6 in that order from left to right, so they are placed below the cylinders 1, 3, and 5.
Second-generation Buick Enclave (2018-2023) firing order
The second-gen model of the Enclave still featured the 3.6-liter V6 as the only available option, although this time it was an updated LFY version. Either way, the engine block is the same and so is the cylinder configuration and firing order for this engine.
That means the second-generation Buick Enclave firing order is 1-2-3-4-5-6 as well, and we’ve already given you the specifics of these engines so we won’t take much of your time discussing the same thing now.
Our take
Overall, the Enclave makes one of the best modern Buick models and it’s all thanks to a rather dependable 3.6-liter V6 engine. So, our team hopes you’ll have a higher chance of keeping it running smoothly thanks to this guide, and make sure to follow the cylinder numbering pattern closely when examining the engine’s cylinders.
