If you are talking about the hose when the engine is completely cooled being hard, then you likely need to replace it. The lower radiator hose is designed to be stiff however, to avoid it from collapsing from the water pump pulling coolant from the radiator.

As far as the gurgling goes, the overflow reservoir shouldn’t make noise unless the radiator cap is leaking or the pressure in the system is strong enough to force it open. You may want to check/replace your radiator cap.
