Detailed Description

Motorad 5173KTFS is engineered as an engine coolant thermostat housing assembly for vehicles that require a 192°F thermostat and OE-specified housing geometry. The housing uses OEM-quality materials and manufacturing processes to meet the demands of modern cooling systems, while the copper case and wax compound help the thermostat react quickly to coolant temperature changes. With a 2-bolt flange design, 1.27 in outlet diameter, 1.38 in bypass diameter, and rubber sealing material, this assembly is built for the cooling-system layout used on select Ford, Lincoln, Mercury, and Mazda platforms. This part cross-references 95173KTFS for the same application.

What It Helps Solve

• Engine temperature fluctuations caused by a worn thermostat housing assembly
• Coolant flow control issues related to thermostat response delay
• Leaks at the housing or seal interface during cooling-system service
• Incorrect thermostat operating temperature for OE-specified applications
• Cooling-system service needs on select Ford, Lincoln, Mercury, and Mazda vehicles

Installation Notes and Tips

Verify the vehicle’s OE thermostat temperature requirement before installation. This assembly uses a 2-bolt housing design and does not include bolts or a separate gasket or seal beyond the included seal noted in the product data. Inspect mating surfaces, flush the cooling system as needed, and confirm hose and outlet alignment before reassembly.

Quality Assurance

Motorad manufactures this Kit line assembly to OEM specifications and safety standards as an OE supplier. The design uses materials selected for cooling-system durability and temperature response, including a copper case and wax compound for consistent thermostat operation.
