  • Copper case and wax compound for quick response to coolant temperature changes
  • Manufactured to OEM specifications and processes
  • Built with OEM-quality materials and safety standards by an OE supplier
  • Sealing flange outside diameter: 2.64 in
  • Bypass diameter: 1.46 in
  • Bypass length: 1.36 in
  • Flange thickness: 0.068 in
  • No gasket or seal included
  • No jiggle pin weep hole

Product Details

Motorad Fail-Safe 7247-174 is an engine coolant thermostat designed for consistent temperature regulation across import cooling systems. The Fail-Safe line is engineered to lock in the open position if overheating occurs, allowing coolant flow to continue rather than restricting circulation. That makes this thermostat a practical OE-style replacement for vehicles such as the 1990-1991 BMW 325i, 1992-1994 Audi S4, and 1978-1985 Mercedes-Benz 300D.

This part cross-references Four Seasons 74774 for the same application. Motorad 7247-174 is also referenced by interchange numbers 97247174 and SS174-7427.

Common Problems It Can Address

  • Engine running too cool or too hot due to a worn thermostat
  • Slow coolant temperature response during warm-up
  • Unstable temperature control in high-load driving
  • Cooling system performance issues caused by thermostat sticking
  • Replacement needs on older BMW, Audi, Mercedes-Benz, Jeep, Volvo, and Volkswagen models

Installation Notes

Verify the 174°F temperature rating and flange dimensions before installation. Because no gasket or seal is included, use the correct separate sealing component for the vehicle application. Clean the thermostat housing mating surfaces thoroughly and inspect the cooling system for contamination, hose wear, or pressure issues before reassembly.
