The thermostat housing on a 2003 Mazda MPV is located at the front of the engine, near the intake manifold, where the upper radiator hose connects to the engine. It's typically situated on the engine block, making it accessible for coolant flow from the radiator to the engine. To reach it, you may need to remove certain components, such as the upper radiator hose, for better access.
