Dayco Radiator Coolant Hose P/N:72989
Dayco 70862 upper radiator coolant hose for the 1976-1979 Chevrolet Corvette carries coolant between the engine and the radiator. This Dayco coolant hose is a single I.D. hose that replaces one that has worn out or started to leak.
Coolant seepage at the ends, a soft or swollen hose, cracks or overheating can mean the hose is worn. A leaking radiator cap, a tired thermostat housing seal or a failing water pump can be behind the same symptoms, so track down the real cause first. Look the hose over with the engine off and cool.
It fits the 1976-1978 Chevrolet Corvette and the 1979 Corvette V8-5.7L. Each car takes one, in the upper position.
