How to identify the cylinder sequence of the Reiz V6?

Method to identify the cylinder sequence of the Reiz V6: The left side of the Reiz V6 is cylinders 1, 3, 5, and the right side is cylinders 2, 4, 6. The flywheel end of the engine is the rear end, and the pulley end is the front end. The cylinder numbering increases from front to back. For an inline 4-cylinder engine, the cylinder closest to the pulley is cylinder 1, and the one closest to the flywheel is cylinder 4. By observing the engine's firing order, you can determine the working sequence of the four cylinders. Below is an introduction to the model: The Reiz V6 is a mid-sized rear-wheel-drive sedan under Toyota, with a wheelbase of 2850 mm, and dimensions of 4750 mm in length, 1795 mm in width, and 1450 mm in height. The Reiz is equipped with two engines: a 2.5-liter naturally aspirated V6 engine and a 3.0-liter V6 naturally aspirated engine.
Hey, after repairing cars for over a decade, the cylinder sequence issue with the Reiz V6 is quite common. Simply put, the cylinder sequence refers to the firing order, usually labeled on a tag under the engine hood near the front, marked as 1-6 or similar. The front left side typically houses cylinders 1, 3, and 5, while the right side has 2, 4, and 6. However, the firing order for Toyota V6 engines is commonly 1-4-2-5-3-6. I usually start by removing the spark plug caps to check the wiring sequence and then cross-reference it with the manual to avoid disassembly mistakes. If the label is missing, use an OBD diagnostic tool to read the data stream—there are tutorials online. Remember to disconnect the battery when working on it yourself to prevent short circuits.
As a car enthusiast, I've driven the Reiz V6 and find it quite intuitive to observe the cylinder firing order. First, open the engine compartment and look for small stickers or engraved markings near the cylinder head with numbers like 1, 2, 3 in the front left row. The firing sequence is typically managed by the Engine Control Module, with cylinders numbered 1 through 6 firing in order. I often refer to forum discussions or YouTube videos, and during actual testing, measuring the coil paths can help deduce the sequence. Regular maintenance includes checking connectors to prevent carbon buildup from affecting judgment.
When I first started learning car repair, I was curious about how to check the cylinder order. The manual is the bible—just flip to the engine section for diagrams. A V6 layout has two rows, labeled 1-6. The firing order usually matches the spark plug wire sequence. Beginners shouldn’t disassemble the engine; checking the label on the cover is the easiest way. If unsure, take a photo of the label and compare it with a database for a safe and accurate method.
