• Jiggle pin weep hole included for air bleeding during service
• No gasket or seal included
• Motorad UltraStat line for demanding cooling system service

Product Details

The Motorad UltraStat line is designed around durable thermostat construction and controlled coolant regulation. Part number 5242-192 uses stainless steel materials for long-term corrosion resistance, while the 192F calibration supports proper engine warm-up and operating temperature management. This thermostat is a direct service choice for 2015-2017 Ford Ranger, 2007-2014 Ford Transit, and 1981-1986 Toyota Pickup cooling system repairs.

This part cross-references Stant 45879 for the same application.

Common Cooling System Issues

• Engine running too cool or taking too long to reach operating temperature
• Temperature fluctuation caused by a worn thermostat
• Coolant flow irregularities after thermostat replacement service
• Corrosion-related thermostat failure in the cooling system
• Air trapped in the system during coolant service

Installation Notes

Verify the thermostat temperature rating and housing dimensions before installation. This unit has a 2.04 inch sealing flange outside diameter, 1.09 inch bypass diameter, 1.37 inch bypass length, and 0.05 inch flange thickness. A gasket or seal is not included, so reuse is not recommended if the original seal is damaged. The jiggle pin weep hole should be oriented to help purge trapped air during filling and bleeding.

Compatible With 2015-2017 Ford Ranger, 2007-2014 Ford Transit, and 1981-1986 Toyota Pickup applications listed above. Part number 5242-192 should be matched to the vehicle’s OE temperature specification before service.
