All 2005 Ford Taurus models came with a 3.0L V6 engine; however, there were three variants of this engine. While they all share the same basic design, and have the same displacement, there are important differences between the three. One engine is suitable for using flex-fuel; another has a higher horsepower output (203 versus 155) than the standard engines. To the naked eye, there are no discernible differences, but there are ways you can determine which engine you have.
Inspect the exterior of the Taurus. If you see a badge that says "FFV" on the fender well, or on the rear, the Taurus is equipped with the 3.0L flex-fuel V6.
Open the hood and inspect the engine compartment. Taurus models equipped with the 203-horsepower engine have markings displayed "24V" or "24-valve."
Count to the eighth digit of the VIN (Vehicle Identification Number). This is the best way to determine which engine your Taurus has. The eighth digit is the engine code for the particular model.
If the eighth digit is "1," the Taurus is equipped with the 3.0L 24-valve Duratec engine. If the eighth digit is "U," the Taurus is equipped with the 3.0L 12-valve (non flex-fuel) engine. If the eighth digit is "2," the Taurus is equipped with the 3.0L flex-fuel engine.
Tips & Warnings
- Locate your VIN by inspecting the area beneath the driver's side of the windshield. You can also locate it on the driver's door jamb.
- If your Taurus has the flex-fuel engine, you can use E85 fuel in it.
