A coolant leak, a soft or swollen hose, or cracks and wear on the hose can mean it needs replacing. A failing thermostat, a worn water pump or a restricted radiator can be behind overheating and coolant loss too, so find the cause before you buy a hose. These vehicles take one lower hose, at the radiator's lower connection.
