The cylinder 2 in a 2007 Nissan Murano’s 3.5-liter V6 is the middle cylinder on Bank 1 (the bank that contains cylinder 1). This engine uses two banks with three cylinders each, labeled 1–3 on Bank 1 and 4–6 on Bank 2.
Understanding the cylinder layout
To orient yourself, remember that the Murano’s V6 is split into two banks of three cylinders. Cylinder numbers increase sequentially within each bank, with Bank 1 housing cylinders 1, 2, and 3, and Bank 2 housing cylinders 4, 5, and 6. Cylinder 2 is the middle cylinder on Bank 1.
- Bank 1 contains cylinders 1–3.
- Bank 2 contains cylinders 4–6.
- Cylinder 2 is the middle cylinder on Bank 1.
In practical terms, cylinder 2 sits between cylinders 1 and 3 on the same bank, and its ignition coil and plug are located along the Bank 1 valve cover row.
Locating cylinder 2 on the engine
To find cylinder 2 on the actual engine, identify the two banks on the V6. Bank 1 is the row that contains cylinder 1; the middle position in that row corresponds to cylinder 2. The ignition coils (one per cylinder) are arranged in two rows of three along each bank, so cylinder 2’s coil is the middle coil on Bank 1. The spark plug beneath it is accessed after removing that coil.
- Locate the two banks with three ignition coils on each valve cover—Bank 1 and Bank 2.
- Identify Bank 1 as the bank that includes cylinder 1; the coils in that row correspond to cylinders 1–3.
- Find the middle coil in Bank 1—that is cylinder 2.
- To service, disconnect the coil, remove the boot to access the spark plug, and follow proper torque specs when reinstalling.
Keep in mind wiring harness routing can vary slightly by model year and market, so consult your service manual or a reliable diagram if you’re unsure.
Summary
On the 2007 Nissan Murano’s 3.5L V6, cylinder 2 is the middle cylinder on Bank 1 (the bank containing cylinder 1). It aligns with the middle ignition coil on that bank, and its spark plug sits beneath that coil. For maintenance, identify Bank 1’s three coils, locate the center one for cylinder 2, and follow standard safety practices when removing and reinstalling components.
