In the 1999 Mazda Protege, the thermostat is located in the engine's coolant system, specifically at the junction where the upper radiator hose connects to the engine block. To access it, you typically need to remove the upper radiator hose and the thermostat housing, which is usually bolted to the engine. Make sure to drain some coolant before removal to prevent spills. Always consult the vehicle's service manual for specific instructions and torque specifications when reassembling.
