It depends on your vehicle's engine type.
3.0 Vulcan, 12 valve engine:
Looking in from the front of the car, it is on the right side of the engine, where the radiator hose goes in - remove the housing's three bolts - the thermostat will be inside
Follow the large top radiator hose to the engine block. It connects to a little dome-shaped fitting held on by three bolts. The thermostat is under it. Be sure to replace the gasket (after completely removing the old gasket) when you replace the thermostat.
3.0 Duratec, 24 valve DOHC engine:
If you have the 24 valve DOHC engine, the thermostat is on the other side (passenger) at the bottom front of the engine, accessible from underneath.
