Motorad 7248-192 Engine Coolant Thermostat

Engine Coolant Thermostat for OE-Style Cooling Control

Motorad Fail-Safe 7248-192 is an engine coolant thermostat built to OE specifications for steady temperature control in demanding cooling systems. It opens at 192°F and uses a copper case with wax compound for quick response to coolant temperature changes.

Compatible With Ford Ranger, Explorer, Explorer Sport Trac, Mustang, Mazda B4000, Mercury Mountaineer, and select Audi, Mercedes-Benz, Jaguar, Volvo, Dodge, and BMW applications. This part cross-references Four Seasons 74892 for the same application.

• Copper case and wax compound for responsive temperature regulation
• Manufactured with OEM-quality materials and OE supplier processes
• Offset design with air relief valve and OEM-style seals where applicable
• Sealing flange outside diameter: 2.64 in
• Bypass diameter: 1.69 in; bypass length: 0.97 in
• Flange thickness: 0.068 in

Product Details

The Motorad Fail-Safe line is engineered for drivers who need consistent coolant control and a built-in protection strategy in the event of overheating. Part number 7248-192 is designed to match OE specifications and processes, making it a direct-fit style thermostat for a wide range of Ford Ranger and Explorer platforms, along with other listed applications such as the Mustang and Mazda B4000. The Fail-Safe mechanism is the defining feature of this product line: if the thermostat is exposed to an overheating event, it locks open so coolant can continue circulating.

Use this thermostat when replacing a worn or sticking unit in vehicles that rely on a 192°F opening temperature for proper engine warm-up and operating stability. The design supports accurate coolant flow control in systems where temperature consistency matters for drivability and engine protection.

What This Thermostat Helps Address

• Engine running too cool or too hot due to thermostat wear
• Delayed coolant circulation from a sticking thermostat
• Temperature instability during stop-and-go driving
• Overheating events caused by thermostat failure
• Loss of OE-style temperature regulation in the cooling system

Installation Notes and Tips

Verify the 192°F temperature rating and match the sealing flange, bypass dimensions, and OE-style configuration before installation. This thermostat does not include a gasket or seal, and no installation tool is included. Clean the housing mating surfaces thoroughly and inspect the cooling system for contamination or restricted flow before fitting the new thermostat.

Fitment examples include 2001-2011 Ford Ranger, 1997-2010 Ford Explorer, 2005-2010 Ford Mustang, 2001-2010 Mazda B4000, and 1998-2010 Mercury Mountaineer. Additional applications include select Audi, Mercedes-Benz, Jaguar, Volvo, Dodge, and BMW models listed in the fitment data.

Quality Assurance

Motorad manufactures this thermostat with OEM-quality materials and OE supplier standards. The Fail-Safe 7248-192 is produced to OE specifications and processes for consistent fit and temperature control across the listed applications.
