Coolant stains around the seams, a rising temperature gauge or a low coolant level can mean the radiator is leaking or clogged. With the engine off and cool, look over the core and plastic tanks for wet spots, cracks or bent fins. Overheating also has other causes, so find the cause before replacing the radiator.
