Before you replace this hose, rule out a loose clamp, a leaking water pump or a sticking thermostat, since those can also lead to coolant loss or overheating. With the engine off and cool, a cracked, soft or swollen hose, or coolant seeping at its surface, can mean it is due for replacement. A vehicle takes one hose, at the lower radiator connection.
