Have you tried using a pick to poke the hole? If it doesn’t work, i’d disconnect the lower radiator hose at the radiator and flush it out that way.

You might be able to poke gently in the hole with an object if the drain plug is off. If it has a top cap vs. just an overflow tank you could siphon the coolant out. Sometimes there is so much scale build up your better off putting a new radiator in.

Agree. Take the plug out and clear it with a small screw driver or piece of wire. The sediment will be soft and easily cleared out of the opening.
