Key Features

• 192F thermostat temperature for OE-specified coolant control
• Fail-Safe thermostat design for added protection in demanding cooling systems

Product Details

This Motorad Kit product line focuses on thermostat housing assemblies that match factory cooling-system requirements. Part number 5172KTFS uses a copper case and wax compound for responsive temperature control, while the housing materials are selected to meet OEM quality standards. It is a practical replacement for drivers servicing a Ford Explorer, Ford Explorer Sport Trac, Ford Ranger, or Mercury Mountaineer with the specified 192F application.

This part cross-references Monroe Shocks & Struts (e.g., 95172KTFS) for the same application.

Common Cooling Issues Addressed

• Engine running cooler or hotter than the specified thermostat range
• Cracked or worn thermostat housing on the coolant outlet side
• Coolant seepage at the housing seal surface
• Delayed thermostat response during temperature changes
• Service replacement for OE-style cooling system maintenance

Installation Notes

Verify the 192F temperature specification and outlet configuration before installation. This assembly uses a three-bolt flange and a rubber seal interface; confirm the mating surface is clean and free of old gasket material. Bolts are not included, and no jiggle pin is provided.
