Replacement RF31960003 Thermostat Housing 2.5L with Temp Sensor & ECT Sensor

The Replacement RF31960003 is an aftermarket engine coolant thermostat housing designed as a direct-fit replacement for the 2.5L four-cylinder engine. This housing serves as the water outlet connection point for the cooling system, securely mounting to the engine and directing coolant flow through the thermostat. It comes pre-fitted with both a temperature sensor and an Engine Coolant Temperature (ECT) sensor, making it a complete drop-in solution. Note: the thermostat and gasket are not included and must be sourced separately.

Key Features:

• Direct OEM replacement — replaces Ford part number F87Z-8592-A (also supersedes F87Z-8592-AL, F87Z-8592-AM, RH83)
• Compatible with the 2.5L four-cylinder engine
• Includes integrated temperature sensor and Engine Coolant Temperature (ECT) sensor ports/sensors
• Functions as the coolant water outlet / water neck connection
• Thermostat and gasket are not included
• Aftermarket replacement — not an OEM part

A failed or cracked thermostat housing can cause coolant leaks and engine overheating. Replacing the housing restores a proper, leak-free seal to the cooling system and ensures accurate coolant temperature readings through the integrated sensors.
