This video shows where the coolant temperature sensor is located in the Ford Focus and how to proceed if you need to replace it. As shown, the sensor is positioned on the left side of the engine at about half height, just below the air filter housing.

Before removing the sensor, ensure the engine is completely cold, then disconnect the retaining clip, pull it out of the housing, and disconnect the power connector.

Finally, insert the replacement part, reassemble everything, and top up the coolant lost during the operation.
