* Check the Vehicle Identification Number (VIN): The VIN contains coded information about the vehicle's specifications, including the engine. You can decode the VIN using online VIN decoders or by contacting a Ford dealership. This is the most reliable method.
* Look in the Owner's Manual: The owner's manual should clearly state the engine size and type.
* Check the Engine Bay: The engine itself usually has a sticker or plate indicating the engine size and other specifications. This information might be on the valve cover, the air intake, or another part of the engine. It's often expressed in liters (e.g., 2.0L, 3.0L).
* Check the Driver's Side Doorjamb Sticker: The sticker on the driver's side doorjamb often lists key vehicle specifications, sometimes including engine size.
* Look up the vehicle's specifications online: Use websites like Edmunds, Kelley Blue Book (KBB), or the Ford website. Enter the year, make, and model of the Escape to find its specifications.
The 2003 Ford Escape came in two engine sizes: a 2.0L four-cylinder or a 3.0L V6. Using the methods above should confirm which one is in *your* specific Escape.
