Detailed Description

Four Seasons 85693 is a thermostat housing for engine coolant components, engineered for cooling system service where the thermostat is not part of the housing assembly. The plastic housing and included seal support a proper fit at the coolant connection point, while the sensor-port application on select Ford Focus models helps maintain the original configuration. Use this Four Seasons thermostat housing 85693 when replacing a cracked, warped, or leaking housing on Ford Focus or Ford Contour applications.

This part cross-references Ford OE numbers XS7Z8592AB and XS7Z8592AC for the same application.

What It Helps Fix

• Coolant leaks at the thermostat housing
• Cracked or heat-damaged plastic housing
• Warped sealing surfaces that allow seepage
• Sensor-port housing replacement on select Ford Focus models
• Cooling system service where the thermostat housing is replaced separately

Installation Notes and Tips

Verify the inlet port diameter, bolt spacing, flange thickness, and overall height against the original part before installation. Transfer or reconnect the sensor only if your vehicle uses the sensor-port configuration shown in fitment. Inspect the mating surface, clean coolant residue, and replace contaminated coolant as part of the repair.

Quality Assurance

Four Seasons 85693 is built to meet or exceed OEM specifications for the listed Ford applications, supporting a direct-fit replacement approach for cooling system maintenance.
