* Your vehicle's paperwork: Your title, registration, or owner's manual will clearly state the engine displacement (e.g., 4.0L or 3.0L). This is the most reliable method.
* The engine bay: Look for an engine identification plate usually located on the driver's side of the engine block. This plate will have the engine's specifications, including the displacement.
* The VIN (Vehicle Identification Number): You can use the VIN to decode the engine type using online VIN decoders or a Ford dealer. This is less direct than the other methods.
The 4.0L Cologne V6 is a much older engine and was used in Rangers for quite some time, while the 3.0L Power Stroke diesel is a more modern engine. The visual differences are not definitive as the engine bay's layout varies slightly across years and models. Therefore, the documentation is the best way to be sure.
