On the 2015 Range Rover V6, bank 1 is generally the bank that includes cylinder number 1. This is often the bank that is slightly forward or more accessible. Bank 2 is then the opposite bank. Now, within each bank, the cylinders are numbered from front to back. So, on bank 1, you'll have cylinders 1, 3, and 5. On bank 2, you'll have cylinders 2, 4, and 6. It’s important to note that the exact layout can sometimes vary slightly depending on the specific engine configuration and whether you're looking at the engine from the front or the back. To avoid any confusion, it’s always a good idea to consult your Range Rover's service manual or a reliable online resource that provides a clear diagram of the cylinder layout for your specific engine. These diagrams will typically show the orientation of the engine, the location of each cylinder, and the numbering sequence. Another helpful tip is to look for markings on the engine itself. Some manufacturers will stamp the cylinder numbers directly onto the engine block or cylinder heads. These markings can be a lifesaver when you're trying to identify the cylinders quickly. Additionally, be aware of the orientation of the engine components, such as the intake manifold and exhaust manifolds. These components can sometimes provide clues as to which bank is which and where each cylinder is located. For example, the intake manifold might have runners that correspond to specific cylinders, or the exhaust manifold might have a particular configuration that aligns with the cylinder layout. Once you've identified the cylinders, take the time to label them clearly. You can use masking tape and a permanent marker to create labels that you can attach to the spark plug wires or ignition coils. This will help you keep track of which cylinder is which when you're working on the engine. Also, keep in mind that the cylinder numbering is not just important for the firing order. It’s also essential for diagnosing other engine issues, such as compression problems or fuel injector failures.
