Ninth-generation Chevy Suburban (2000-2006) firing order
As the first generation of the Suburban that extended through the 2000s, the ninth-gen model was equipped with several optional V8s. However, not all of these feature the same layout and firing sequence so we’ll clear things up a bit for you.
Chevy Suburban 5.3L firing order
As the first engine on our list, we’ve got a base version of the V8 and that’s the 5.3-liter engine. So, the Chevy Suburban 5.3L firing order is 1-8-7-2-6-5-4-3 and this one is based on the LS4 engine used in the Impala back in the day.
So, the engine is transversely placed in the engine bay and the upper cylinder bank houses the first cylinder along with cylinder numbers 3, 5, and 7. The lower bank includes cylinders 2, 4, 6, and 8 and the specific thing about this engine is that all the cylinders are arranged from right to left in their respective banks.
Chevy Suburban 5.7L firing order
The 5.7-liter engine is usually used as a high-performance option in passenger cars like the Camaro, but this time it’s yet another base option for the Suburban. However, it’s important to note the differences between this engine and the previous 5.3-liter V8.
So, the Chevy Suburban 5.7L firing order is 1-8-4-3-6-5-7-2 and this one is placed in the engine bay longitudinally. The driver’s side cylinder bank houses cylinders 1, 3, 5, and 7 while the passenger’s side bank includes cylinders 2, 4, 6, and 8.
Chevy Suburban 6.0L firing order
As the final option of the ninth-gen Suburban, we have yet another V8 and this time it’s a larger 6.0-liter engine. It’s important to note that the Chevy Suburban 6.0L firing order is 1-8-7-2-6-5-4-3 and once again the cylinders are arranged 1, 3, 5, 7 on the driver’s side, and 2, 4, 6, and 8 on the passenger’s side.
Tenth-generation Chevy Suburban (2007-2014) firing order
For the tenth-gen Suburban model, things haven’t changed much so Chevy still offered the same 5.3-liter and 6.0-liter V8s. However, the 5.7-liter one was replaced by the 6.2-liter LS-based engine that’s similar to the one found in the Camaro, so we’ll discuss that one.
Chevy Suburban 6.2L firing order
The Chevy Suburban 6.2L firing order is 1-8-7-2-6-5-4-3 and this engine once again features a common Chevy’s V8 cylinder layout. The first cylinder is located in the driver’s side cylinder bank and it’s the first cylinder at the front of the engine.
Moving on from the front to the rear, you’ll also find cylinders 3, 5, and 7. Cylinders 2, 4, 6, and 8 are on the opposite side also oriented from the front end toward the rear end of the engine.
Eleventh-generation Chevy Suburban (2015-2020) firing order
For the eleventh generation of the Suburban, Chevy didn’t experiment too much, so once again we had the old 5.3-liter V8 and the 6.2-liter engine. Nothing else changed and we didn’t get any newly-introduced engine options, so let’s move on with the current generation of the Suburban.
Twelfth-generation Chevy Suburban (2021-2023) firing order
Finally, we reach the ongoing generation of the Suburban and this one also features the main 5.3L and 6.2L V8 options. Once again these use the same layout and configuration along with the firing order that we already discussed, so we’ll focus on a newly added 3.0-liter Duramax diesel powertrain.
Chevy Suburban 3.0L Duramax firing order
The Chevy Suburban 3.0L Duramax firing order is 1-5-3-6-2-4 and this one is a straight-six diesel-powered engine. So, it also features a specific cylinder configuration since the first cylinder is at the front end of the engine and the rest goes from 1 to 6 in straight order toward the rear end.
This one may not come with some regular issues of petrol-powered Suburban engines like cylinder misfires, but now that you know the firing order you can deal with engine stalling issues.
