About this part

Heater hoses move hot coolant from the engine to the heater core and back. After decades of heat cycles they harden, swell or crack near the clamps. The Dayco 80418 is a 3/4 inch hose for the heater circuit of a 1980 Corvette. A soft or bulging hose is a warning sign, and a burst one can dump coolant fast and overheat the engine. Fresh hose restores heat in the cabin and removes a common leak point.
