QUICK ANSWER

The K24A/K24Z 2.4L Inline-Four firing order is 1-3-4-2. Cylinders are numbered 1-2-3-4 in one row from the timing-chain end toward the transmission.

Application note: Covers production K24A- and K24Z-family inline-four engines using the standard crankshaft and PCM strategy. Later direct-injected K24W engines, mixed K20/K24 builds and racing crankshafts require their exact engine or component documentation.

The K24A/K24Z 2.4L Inline-Four firing order is 1-3-4-2. Cylinders are numbered 1-2-3-4 in one row from the timing-chain end toward the transmission. The order is simple to print; the difficult part is applying it to the correct physical cylinders. Factory-manual-derived K24 service data lists the 1-3-4-2 combustion order. Because the engine has one cylinder row, timing-chain-end orientation is more dependable than left/right language, which changes with where the observer stands.

A firing-order diagram should answer three separate questions: which cylinder is which, what sequence the crankshaft uses, and how the ignition system reaches each cylinder. The coil-harness branches may not appear in simple 1-2-3-4 order after routing around the valve cover. Label connectors by physical cylinder before unplugging them and interpret a P030x code by cylinder number, not firing-event position. The interactive drawing below keeps the order visible while the table preserves the numbering notes in crawlable text.

Before disconnecting anything, photograph the harness or leads, label both ends, and identify the engine from a durable source. That five-minute audit is faster than diagnosing a crossed pair after the engine has been reassembled.

Reading the K24A/K24Z 2.4L Inline-Four diagram correctly

Cylinders are numbered 1-2-3-4 in one row from the timing-chain 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 1-3-4-2 begins the sequence but does not define a universal connector position.

Factory-manual-derived K24 service data lists the 1-3-4-2 combustion order. Because the engine has one cylinder row, timing-chain-end orientation is more dependable than left/right language, which changes with where the observer stands. The coil-harness branches may not appear in simple 1-2-3-4 order after routing around the valve cover. Label connectors by physical cylinder before unplugging them and interpret a P030x code by cylinder number, not firing-event position. On coil-on-plug engines, use the diagram for cylinder identity and diagnosis; the PCM, not a physical distributor cap, schedules spark.

Which K24A/K24Z 2.4L Inline-Four firing order applies?

Factory-manual-derived K24 service data lists the 1-3-4-2 combustion order. Because the engine has one cylinder row, timing-chain-end orientation is more dependable than left/right language, which changes with where the observer stands. 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 1-3-4-2 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.
