Toyota 3.5 V6 2GR-FE Firing Order Diagram

Reading the 2010 Highlander 3.5L 2GR-FE V6 diagram correctly

On the covered transverse Highlander installation, the rear/firewall Bank 1 carries 1-3-5 and the front/radiator Bank 2 carries 2-4-6; cylinders on each bank run from the timing-drive end toward the transmission. Read the vehicle as installed and use the manufacturer's left/right convention, not the side from which you happen to be standing. The first cylinder listed in 1-2-3-4-5-6 begins the sequence but does not define a universal connector position.

Toyota service data explicitly lists 1-2-3-4-5-6. That sequential notation is the combustion order, not a single physical row: consecutive events alternate between the odd- and even-numbered cylinder banks. Use engine code and installed orientation before calling a coil front, rear, left or right. Bank 1 is the bank containing cylinder 1, not a universal driver-side designation. On coil-on-plug engines, use the diagram for cylinder identity and diagnosis; the PCM, not a physical distributor cap, schedules spark.

Which 2010 Highlander 3.5L 2GR-FE V6 firing order applies?

Toyota service data explicitly lists 1-2-3-4-5-6. That sequential notation is the combustion order, not a single physical row: consecutive events alternate between the odd- and even-numbered cylinder banks. This distinction matters because the engine can look nearly identical from above. Treat the camshaft or engine assembly as the authority when parts have been mixed. A firing order cast into an intake, copied from a generic decal, or remembered from another V8 is not enough to identify a modified engine.

The application table separates the order, cylinder banks, and ignition-system notes. Read all columns before routing. The first number in 1-2-3-4-5-6 is cylinder 1, but the physical No. 1 terminal can appear in different clock positions when a distributor has been installed on a different gear tooth.
