* Check the Vehicle Emission Control Information (VECI) sticker: This sticker is usually located on the driver's side doorjamb or the engine compartment. It will list the engine code (e.g., 1UZ-FE for a Lexus, but will be a Ford code for your Sable). This code can then be cross-referenced online to find the specific engine type.
* Look at the engine itself: The engine block will usually have a casting number stamped on it. This number can be cross-referenced with Ford documentation to determine the exact engine. You might need a flashlight and possibly a mirror to see all the numbers clearly. The location of this number varies slightly depending on the specific engine.
* Consult your owner's manual: Your owner's manual should specify the engine type.
* Use your vehicle identification number (VIN): You can use your VIN to look up the vehicle's specifications online through several sources. Many online VIN decoders are available, but make sure to use a reputable site.
* Check your title or registration: In some cases, this may list the engine displacement (e.g., 3.0L).
The most common engines in the 1999 Mercury Sable were the Duratec 2.5L V6 and the Vulcan 3.0L V6. Knowing this might help you narrow down your search if other methods prove difficult.
