* Vehicle Identification Number (VIN): The VIN, located on the driver's side dashboard, contains information that can be decoded to reveal the engine size. You'll need a VIN decoder (many free online tools are available) to do this.
* Owner's Manual: Your owner's manual should specify the engine size on the first few pages, usually on a sticker or in a specifications section.
* Engine Bay: The engine size might be stamped directly onto a part of the engine block itself, though this is not always easy to find or read.
* Vehicle Registration: Some vehicle registration documents may list engine displacement.
* Ford's Website: While you can't simply enter the year and get the engine size, Ford's website might have resources to help you find build specifications if you know other details about your specific Ranger (like trim level).
Therefore, checking your owner's manual or using a VIN decoder is the most reliable method to quickly determine the engine size of your 1999 Ford Ranger.
