On a 2003 Cadillac CTS, the thermostat is located in the engine compartment. Specifically, it is situated on the engine's upper intake manifold, near the engine's front, where the upper radiator hose connects to the engine. To access it, you typically need to remove the engine cover and possibly the intake duct.
