Cylinder 5 is the middle cylinder on the passenger-side bank of the 3.5L V6 (2GR-FE) engine in the 2007 Avalon, when looking at the engine from the front of the car.
The 2007 Avalon uses Toyota’s 3.5-liter V6 engine (2GR-FE). In this layout, the engine comprises two banks of three cylinders each. Cylinders 4-6 occupy one bank, while cylinders 1-3 occupy the opposite bank. Within each bank, the cylinders are arranged front to back, so the middle cylinder on the bank that contains cylinders 4, 5, and 6 is cylinder 5.
Engine layout and cylinder numbering
Understanding the layout helps you locate cylinder 5 quickly. The 2GR-FE uses coil-on-plug ignition for each cylinder, with the coils mounted along the valve covers on both banks. On the bank that hosts cylinders 4–6, cylinder 5 is the middle position when viewed from the front of the engine.
Practical guide to finding cylinder 5
Before you begin, note that the following steps assume a standard front-facing view of the engine with the hood raised. If your car has an after-market engine cover or different labeling, adapt accordingly.
- Stand in front of the car and remove the engine cover if present to expose the valve covers and coil packs.
- Identify the bank that contains cylinders 4, 5, and 6 (the passenger-side bank in most US-spec vehicles). Locate the three coil packs along that valve cover.
- Count from the front toward the rear on that bank; the middle coil pack corresponds to cylinder 5, and the spark plug beneath it is the cylinder’s plug.
In summary, cylinder 5 is the middle cylinder on the passenger-side bank (cylinders 4-6) of the 2GR-FE V6 in the 2007 Toyota Avalon. Use the middle coil on that bank to identify or service cylinder 5, ensuring the engine is cool and safety precautions are followed.
Summary: For a 2007 Avalon, cylinder 5 is the middle cylinder on the bank that contains cylinders 4, 5, and 6. This is the passenger-side bank when facing the engine from the front; locate the middle coil/plug on that bank for access to cylinder 5.
