Ford Bronco ECT Sensor Removal & Installation - Torque Spec 13-20 Nm (12A648)

This is a page from a Ford factory service manual covering removal and installation of the Engine Coolant Temperature (ECT) sensor. The procedure lists five steps: partially drain the cooling system per Section 03-03, disconnect the negative battery cable, disconnect the engine control sensor wiring from the coolant temperature sensor, remove the sensor from the intake manifold, and reverse the removal steps to install, torquing the sensor to 13-20 N·m (10-15 ft-lb) and refilling the coolant per Section 03-03. Two line drawings illustrate the sensor location: the first shows the ECT sensor threading into a fitting on the intake manifold with a 'FRONT OF ENGINE' orientation arrow, labeled with the sensor base part number 12A648 and its torque specification. A second partial illustration at the bottom of the page repeats the coolant temperature sensor callout and torque value. Faint show-through from an adjacent page references the idle air control valve, intake air temperature sensor (12A697), gasket, and throttle body. The right column of text is cut off at the page edge, so steps 4 and 5 are only partially readable. A reader learns the exact removal sequence and torque spec for the ECT sensor.
