Dayco Radiator Coolant Hose P/N:72341
Dayco 70755 upper radiator coolant hose for the 1971-1973 Ford Mustang V8 5.0L and other vehicles carries hot coolant from the engine to the radiator. This Dayco radiator coolant hose replaces one that has aged, leaked or gone soft.
A coolant leak at the hose, cracked or swollen rubber, or an engine running hot can mean the hose needs replacing. These signs alone do not prove the hose is at fault, since a thermostat stuck closed is another common source of overheating.
The 1971-1973 Ford Mustang V8 5.0L, the 1974-1978 Jeep Cherokee V8 6.6L, the 1974-1983 Cherokee V8 5.9L and the 1984-1991 Jeep Grand Wagoneer all take this hose, along with many other vehicles. Each takes one.
