What is the caution regarding the ECT sensor and how should it be installed?

You should not reuse the ECT sensor and always install a new one. For 1.5L and 1.6L, remove the engine cover, expansion tank, and air filter housing to access the sensor on the thermostat housing. Disconnect the connector, remove the clip, and pull out the sensor.
