Dayco Radiator Coolant Hose P/N:70622
Dayco 70871 upper radiator coolant hose for the 1977-1979 Ford F-150 V8 5.8L or 6.6L and other vehicles carries hot coolant from the engine to the radiator.
A hose that is swollen, cracked or weeping coolant at the ends can mean it is worn, though a weak radiator cap or a tired thermostat can be behind overheating and coolant loss too. Check the hose by eye only with the engine off and cool.
In the cooling system's upper position, this Dayco coolant hose also fits the 1977-1979 Ford F-250 V8 5.8L or 6.6L and the 1978-1979 Ford Bronco V8 5.8L or 6.6L. The engine takes a single hose.
