For drivers searching for a 180F thermostat with seal for Chevrolet Camaro, Pontiac Firebird, or Chevrolet Corvette cooling system service, this thermostat provides the dimensions and sealing features needed for a direct-fit style replacement where specified by the vehicle application.

Common Cooling Issues It Can Address

• Engine running cooler or warmer than the specified operating range
• Delayed coolant circulation after cold start
• Temperature fluctuation caused by a worn thermostat element
• Cooling-system service where the original thermostat seal is no longer sealing properly
• Air trapped in the cooling system after thermostat replacement

Installation Notes and Tips

Verify the thermostat temperature rating, flange dimensions, and bypass measurements against the original part before installation. Clean the housing mating surfaces thoroughly and replace the seal supplied with the thermostat. The jiggle pin weep hole should be positioned to help air escape during filling, and the cooling system should be refilled and bled according to the vehicle service procedure.
