• Description:

  This Genuine Ford ML3Z-8475-E is the sibling-suffix engine coolant thermostat or thermostat housing variant for 21-25 F-150 applications, covering a specific engine package or temperature calibration that differs from the D-suffix. The thermostat regulates coolant flow between the engine block and the radiator, opening as coolant temperature rises through the calibrated opening range so cooled coolant from the radiator returns to the engine and closed-loop temperature control is maintained within the factory operating window. The integrated housing includes the temperature sensor port and the upper-radiator-hose connection. Owners replace this thermostat when an overheating condition traces to a stuck-closed thermostat that prevents coolant from circulating to the radiator, when a slow-warmup condition traces to a stuck-open thermostat that lets coolant flow before the engine reaches operating temperature, when a coolant leak appears at the thermostat housing seal, when a temperature-sensor DTC traces to the integrated sensor port, or when a major engine repair includes the thermostat as a preventive replacement. Installation requires the cooling system to be drained, the upper radiator hose detached, the original housing unbolted, and the new thermostat installed with a fresh gasket before fresh coolant is added. Confirm engine package by VIN.
