How are the cylinders numbered on a v6 Chevrolet engine?

Chevrolet V6 engine cylinder numbering follows a standard pattern, but the specific arrangement depends on whether it's a left-bank-first or right-bank-first engine. There's no universal "always this way" rule across all Chevrolet V6s.

To know for certain, you MUST:

* Consult the engine's specific service manual: This will have a diagram showing the exact cylinder numbering.

* Look at the engine itself: The cylinder numbers are sometimes cast directly onto the engine block, usually near the top of each cylinder.

General Pattern:

Most Chevrolet V6s use a sequential numbering system, starting from one end of the engine (either the left or right bank) and proceeding sequentially across the engine to the other bank and back. But which bank starts with #1 varies.

* Left Bank First: 1-3-5 would be the left bank, 2-4-6 the right.

* Right Bank First: 1-3-5 would be the right bank, 2-4-6 the left.

Without a specific engine code or model year, it's impossible to give a definitive answer.
