How to remove the cylinder head temperature (CHT) sensor in Ford Focus?

All engines, except the 2.0L SPI, have a cylinder head temperature (CHT) sensor, unlike the 2.0L SPI's coolant temperature sensor. For 2.0L Zetec-E engines, remove the alternator and disconnect the sensor's wiring connector. On 2.3L and 2005 and later 2.0L engines, the CHT sensor is on top of the engine, while on other non-SPI engines, it's on the cylinder head side. For 2.0L SPI engines, remove the ignition coilpack and drain the cooling system. After removing the sensor, follow the reverse order for installation, ensuring the sensor is tightly screwed and reconnected. Reinstall any removed components and refill the cooling system for 2.0L SPI engines.
