Bypass hoses allow coolant inside the engine to expand to other parts of the cooling system before the thermostat opens. Most often this will include the heater core.

Leaking bypass hoses will cause coolant loss and potentially damage the cooling system. They should be replaced as soon as possible.

Replacing a bypass hose is typically just a matter of draining the fluid below the lowest point of the hose, pulling it off and installing the new one.
