How to replace the CHT sensor and ECT sensor in Lincoln MKX?

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.

How to replace the Engine Coolant Temperature (ECT) sensor on Lincoln MKX?

The Engine Coolant Temperature (ECT) sensor is located on the driver's side of the cylinder head in four-cylinder models and between the cylinder banks in 2.7L V6 models. To replace it, remove the intake manifold, disconnect the electrical connector, and unscrew the old sensor. Install the new sensor and tighten it.
