It's possible to clean them out but you might not be able to do it yourself.. it's probably easier to just get a new one or a clean one from a junkyard.
I don't know how much luck you would have trying to flush the cooling system with a garden hose either. Chances are if it's clogged it will all be in the radiator or heater core.
