Product Details

Motorad UltraStat thermostats are engineered for direct engine coolant temperature control in applications that call for a 192°F opening temperature. This part number, 5248-192, is listed for multiple OE-style fitments including 2001-2011 Ford Ranger, 2005-2010 Ford Mustang, 1997-2000 Ford Explorer, 2001-2009 Mazda B4000, and 1998-2010 Mercury Mountaineer. It also cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Uses

• Replacing a thermostat that is stuck open or stuck closed
• Correcting engine temperature that runs too cool or too hot
• Restoring proper coolant flow control after thermostat failure
• Addressing temperature fluctuation during warm-up or driving
• Servicing cooling systems that require a 192°F thermostat

Installation Notes

Verify the thermostat temperature rating, bypass dimensions, and flange measurements before installation. Because no gasket or seal is included, confirm the correct sealing component for the application before assembly. Clean the housing and mating surfaces thoroughly, and follow the vehicle service procedure for coolant refill and air bleeding.

Quality Assurance

UltraStat thermostats use stainless steel construction for durability and corrosion resistance, along with BLVT valve technology to reduce cooling-system shock during operation. Part number 5248-192 is built to meet OE specifications for engine coolant temperature control across the listed applications.
