Dayco Radiator Coolant Hose P/N:70622
Dayco 71645 upper radiator coolant hose for the 1992-1994 Chevrolet Corvette V8 5.7L carries engine coolant on the upper run between the pipe and the engine. The Dayco coolant hose is a dual I.D. hose made of EPDM.
Coolant seepage at the hose ends, cracks, a soft or swollen hose, or a temperature gauge that climbs can mean this hose is worn, though a weak thermostat or a tired radiator cap can be behind the same signs.
This hose fits the 1992-1994 Chevrolet Corvette V8 5.7L, which takes one hose per car.
