Coolant that keeps dropping, wet spots or crusty residue on the core and tank seams, or an engine that runs hotter than normal can mean the radiator is leaking or clogged. With the engine cool, look over the core, tanks and fittings for cracks or seepage first, since a hose or water pump leak looks much alike. A shop can pressure-test the system.
