The thermostat on a 1995 Lincoln Continental with the 4.6L V8 engine is located on the engine block,
at the lower part of the intake manifold. It's generally not readily visible without some disassembly; you'll likely need to remove some parts to access it. Specifically, you'll probably need to remove the upper radiator hose and possibly some other components to get a clear shot.
It's a somewhat involved job, not a simple "pop the hood and there it is" situation. A repair manual specific to your vehicle year and engine is highly recommended before attempting this repair. Consult a mechanic if you're not comfortable working on your engine yourself.
