Detailed Description

The Motorad Standard 248-174JV is an engine coolant thermostat designed to maintain stable operating temperature by regulating coolant flow through the engine cooling system. Its 170°F opening point supports proper warm-up and temperature control in vehicles that specify this calibration. The copper case and wax element are selected for fast response to coolant temperature changes, while the jiggle pin weep hole helps purge trapped air during service. This part cross-references Gates 24875 and Anchor 3527 for the same application.

Compatible With 2001-2010 Ford Explorer, N/A; 2010 Mazda B4000, N/A; 1994-1999 Mercedes-Benz S320, N/A; 1987-1997 Jaguar XJ6, N/A; 1986-1993 Mercedes-Benz 300E, N/A; and other listed applications across 1959-2010 model years. The 248-174JV is also listed for Mercedes-Benz 190E, 300CE, 300SE, 300SL, 300TE, 260E, 300D, 380SL, Volvo 760, Volvo 780, Jaguar XJS, Jaguar XJR, and Porsche 928 applications where the specified thermostat temperature and dimensions match.

What It Helps Address

• Engine running too cool or taking too long to reach operating temperature
• Temperature fluctuation caused by a worn thermostat element
• Coolant flow control issues in high-mileage cooling systems
• Air trapped in the cooling circuit during thermostat service
• Incorrect thermostat temperature for OE-specified applications

Installation Notes and Tips

Verify the required temperature rating, flange dimensions, and bypass measurements before installation. This thermostat does not include a gasket or seal, and no installation tool is included. Clean the housing sealing surfaces thoroughly and confirm the jiggle pin weep hole is oriented per the vehicle service procedure. For fitment-specific searches, this part is commonly selected for Ford Explorer thermostat replacement, Mercedes-Benz 300E coolant thermostat service, and Jaguar XJ6 engine cooling repair.

Quality Assurance

Motorad manufactures this Standard thermostat using OEM-quality materials and OE supplier processes to meet original-style cooling system requirements. The copper case, wax compound, and OEM-style design details are intended to support consistent operation in demanding automotive cooling applications.
