Honda 3.0L (182 cu in) firing order — diagram & guide

As one of the engines that stuck in Honda’s offering for the longest time, the 3.0-liter V6 is pretty well-known to automotive enthusiasts. While the engine was often going through revisions, it always kept its engine block and cylinder outline, so the same Honda 3.0L (182 cu in) firing order can be used for all variations.

Well, that’s at least if you know what it is and how to apply it, and if not, our team will be your guide through this engine and its firing sequence.

Honda 3.0L V6 firing order

To get the biggest thing right out of our way, the Honda 3.0L V6 firing order is 1-4-2-5-3-6, so it’s a bit different than what you may be used to for other Honda engines. There were several variations of this engine, including the options codenamed J30A, J30A1, and J30A2.

Still, it all came down to the same thing, and that’s using the 1-4-2-5-3-6 Honda firing order to look for signs of trouble under the hood. You can sort out misfires and figure out which cylinder needs the spark plugs and coil packs replaced, but first, you have to know how the cylinders are arranged.

The good thing about this engine is that it features the same standard configuration as other V6 engines made by Honda back in the day. This means that there are two cylinder banks and cylinders on the left side are 1, 2, and 3, while cylinders on the right side are 4, 5, and 6, looking from front to back.

Because of this, it’s easy to identify the first cylinder which is on the passenger’s side, and the one at the front-most end of the engine.
