In the 2003 Ford Taurus, you can find the thermostat located in the thermostat housing on the lower coolant line. This component is crucial as it assesses the temperature of the coolant flowing through the line, enabling it to determine the engine's operating temperature. If the thermostat malfunctions, it can lead to the engine overheating, which is detrimental to the vehicle. Overheating may cause damage such as warping or cracking the head gasket, resulting in expensive repairs down the road. If your check engine light indicates a faulty thermostat, it is vital to address the issue promptly. A full replacement typically costs around $200, so delaying the fix is not advisable.
The engine coolant temperature sensor for the 2003 Ford Taurus can be found in the coolant pipe, situated below the air intake pipe and behind the right cylinder head. It is combined with the ECT sensor for optimal functionality.
