The EGR valve on a 2005 Dodge Magnum 3.5L V6 is typically located on the
intake manifold. It's not easily visible without removing some components. You'll likely need to remove parts of the intake system to access it properly. A repair manual specific to your year and model will provide the most accurate location and removal instructions.
Keep in mind that the exact location can vary slightly depending on specific engine variations within that model year, so a visual inspection with the help of a repair manual is highly recommended. Don't try to blindly locate it without knowing what you're looking for, as you could damage other parts of the engine.
