Get hose clamps at an autoparts store, not those screw things that chew up hoses at a hardware store. The inside of the clamp must be smooth, including the adjusting area.

Remember, do not gorilla the hose clamps at the radiator end. That is plastic!!! and it will crack under too much force. Snug enough so that the hose will not slide if you try to twist it.

they're called "otiker" clamps. Either pry up the ennd and pop it off the tab or just cut em off with dykes. The tool required to close the new ones is available from grainger for about $45. I would use screw type clamps and call it good

They're likely from the factory, though many shops use them. They're much cheaper than screw clamps. However, they tend to be one use only, and you need tools to set them. Take them off you'll likely break them (which means you've got to replace them, I recommend screw clamps) but you can use needle nose or a screwdriver to undo that "bow-tie" so it'll loosen then rip it off.
