How to test and replace the engine coolant temperature sensor for Cadillac ElDorado and Fleetwood?

The engine coolant temperature sensor, a thermistor in the coolant stream, varies resistance with temperature. The PCM uses a 5-volt signal to determine the coolant temperature based on this resistance. Testing requires comparing resistance to a chart and checking against an automotive thermometer. If it's off-spec, replace the sensor. Located near the thermostat housing, ensure coolant is drained before removal. Coat the new sensor with thread sealant, tighten to the recommended torque, refill coolant, and reconnect the battery cable.
