A cracked, swollen or wet hose, a coolant leak or a heater that blows cool air may point to this hose. A heater that blows cool air does not prove the hose is at fault, since a stuck thermostat can give the same result, so find the cause before replacing it. Inspect the hose only with the engine off and cool.
