Product Details

Motorad’s Fail-Safe line focuses on thermostat protection and dependable temperature regulation for automotive cooling systems. Part number 7211-160 is engineered as an OE-style engine coolant thermostat with a copper case and wax element that responds quickly to coolant temperature changes. The Fail-Safe mechanism is designed to remain open after an overheating event, helping maintain coolant circulation when the system has been stressed.

This part cross-references Dayco 71160 for the same application. It is a direct replacement choice for service on Pontiac Fiero, Buick Skylark, and Chevrolet Citation models where a 160F thermostat is specified.

What It Helps Address

  • Engine temperature fluctuations caused by a worn thermostat
  • Delayed coolant flow during cold-to-hot temperature transitions
  • Overheating events related to thermostat sticking
  • Cooling system service needs on older GM compact and mid-size vehicles
  • Replacement of a thermostat with an included rubber seal

Installation Notes

  • Verify the thermostat temperature rating and flange dimensions before installation
  • Inspect the thermostat housing and sealing surface for corrosion or debris
  • Use fresh coolant and follow the vehicle service procedure for bleeding air from the system
  • Confirm the gasket/seal is seated correctly before closing the housing
  • Fits 1986-1994 Pontiac Sunbird, N/A; 1990-1992 Chevrolet Lumina, N/A; 1989-1990 Pontiac LeMans, N/A; 1988-1990 Pontiac Optima, N/A; 1985-1989 Pontiac Grand Am, N/A; 1982-1988 Buick Skyhawk, N/A; 1982-1988 Buick Skylark, N/A; 1988 Oldsmobile Cutlass Calais, N/A; 1982-1988 Oldsmobile Firenza, N/A; 1984-1988 Pontiac Fiero, N/A; 1985-1987 Oldsmobile Calais, N/A; 1984-1985 Chevrolet Citation II, N/A; 1984-1985 Pontiac J2000 Sunbird, N/A; 1982-1984 Oldsmobile Omega, N/A; 1982-1984 Pontiac Phoenix, N/A; 1982-1983 Chevrolet Citation, N/A; 1982-1983 Pontiac J2000, N/A
