Four-cylinder models have an Engine Coolant Temperature (ECT) sensor and a Cylinder Head Temperature (CHT) sensor. The ECT sensor is the coolant temperature-sending unit for the temperature gauge, and the CHT sensor is the temperature sensor for the PCM. To replace the CHT sensor, drain the cooling system. For these models, remove the air cleaner outlet duct and the purge valve/tube retaining bracket bolts. Disconnect the sensor's electrical connector, remove the retaining clip and the sensor, and discard the O-ring. Install a new O-ring and refill the cooling system.

In the case of a four-cylinder engine, the buyer should start with the draining of the cooling system. The ECT sensor is mounted on the water outlet housing at left side of cylinder head. To take out the sensor, one has to remove the electrical connector, the retaining clip, and the sensor, the O-ring is also disposed of. Installation is done in the reverse manner that it was done during removal, you have to use a new O-ring and then you end up refilling your cooling system. First for a 3.0L V6 engine, remove all the engine coolant. Remove the electrical connector from the ECT sensor and then remove the locking tab found at the bottom of the sensor, rotate the sensor anti-clockwise until it is unbolted from the coolant passage. Check on the sensor O-ring for any signs of cuts or signs of deterioration, if any then replace it. For fitting of the ECT sensor, it is simply screwed into the coolant passage and rotated clockwise until a locking tab fits in place, in the reverse of the disconnection process for the rest of the installation of the new parts. Last but not the least, the cooling system should be refilled.

Disconnect the electrical connector, pull out the locking tab, rotate the sensor counterclockwise, and remove it from the coolant passage.

2.7L V6 models.

The intake manifold needs to be removed in order to replace the ECT sensor on four-cylinder models.

After disconnecting the electrical connector to the ECT sensor, the sensor should be unscrewed from the engine and discarded.
