Detailed Description

Motorad Fail-Safe 7307-180 is engineered as an OE supplier thermostat manufactured to OEM quality materials, specifications, and processes. The Fail-Safe design locks open during an overheating event to maintain coolant circulation, while the copper case and wax element help the thermostat react quickly as coolant temperature changes. This makes it a direct-fit choice for drivers servicing 1992-1997 Chevrolet Camaro and Corvette, 1993-1997 Pontiac Firebird, and other listed GM applications that call for a 180F thermostat. This part cross-references Four Seasons 73078 for the same application.

What It Helps Address

• Engine overheating caused by a thermostat that no longer opens correctly
• Slow warm-up or unstable operating temperature from a worn coolant thermostat
• Coolant flow interruption in systems that require a Fail-Safe open position
• Air trapped in the cooling system during thermostat service
• Fitment issues when replacing an OE-specified 180F thermostat

Installation Notes and Tips

Verify the thermostat temperature rating and housing style before installation. The included rubber seal should be seated cleanly to prevent coolant leaks, and the jiggle pin weep hole should be oriented to help purge trapped air. Confirm bypass dimensions and flange measurements against the original part when servicing a Chevrolet Camaro, Pontiac Firebird, or other listed application. Part number 7307-180 should be matched to the vehicle’s OE specification before assembly.
