In the 2005 Chevy Impala, the thermostat is located in the thermostat housing on the lower coolant line. The thermostat is responsible for monitoring the temperature of the coolant as it flows through the line, allowing it to determine the engine's operating temperature. If the thermostat fails, there is a danger of the engine overheating, leading to potential damage. An overheated engine could result in the warping or cracking of the head gasket, which can be a costly repair job. If the check engine light indicates an issue with the thermostat, it's crucial to address it promptly. A full replacement typically costs around $200, so it's best not to delay in getting it fixed.

The engine coolant temperature sensor, known as the ECT sensor, can be found on the 3.8 liter engine and near the thermostat on the intake manifold of the 3.4 liter engine. If it's faulty, it might need replacement. In addition to that, verify the continuity of the sensor circuit and make sure the temperature gauge is working correctly.
