There's no single firing order for all V6 Dodge truck engines. The firing order varies depending on the specific engine's design and year. To find the correct firing order for your Dodge truck's V6 engine, you
must consult your owner's manual or a reliable online resource like a repair manual specific to your year, make, and model.
Looking up the engine's displacement (e.g., 3.7L, 3.9L, etc.) will also help narrow down the search for the correct firing order.
