Acura 3.0L (182 cu in) firing order — what is it?
Insights into the Acura 3.0L firing order for improved engine balance and longevity.
Ever since its first appearance in the Acura CL back in the late 90s, the 3.0-liter V6 engine became a staple in Acura’s lineup. These days we can witness the newly-developed turbocharged version of the engine in the “Type S” models, and regardless of which version you own, there are common maintenance tasks you need to do.
If you are a DIYer, we’ll do our best to make that task easier for you through our Acura 3.0L (182 cu in) firing order guide. Not only will we go through the firing sequence of the engine, but we’ll also tell you how to utilize it for the benefit of your engine’s longevity.
Acura 3.0L firing order
Before we get started, it’s important to state that the Acura 3.0L engine has been present since 1996 and is still going strong in today’s MDX and TSX models. However, the engine evolved over time and even gained a twin-scroll turbocharger in the modern-day high-performance models.
Still, the Acura 3.0L firing order is 1-4-2-5-3-6 for all the versions including the latest high-performance turbo edition crafted in 2021. Now that you know the most important piece of information about this engine and its upkeep, you may be wondering how you can use it.
Well, it’s enough to follow the firing pattern when checking the engine’s cylinders. If you get an OBD2 code signifying misfires, you can figure out which cylinder is misfiring this way. The same goes for checking spark plugs and ignition coils, so all this can be done by knowing the firing order and the cylinder configuration of the engine.
