Coolant stains under the front of the car, steam or a climbing temperature gauge can mean a radiator is leaking or restricted. With the engine off and cool, look over the tanks and core for cracks, wet spots or crusty residue, and trace any wet spot to its source before replacing the radiator, since a hose or clamp leak looks much the same.
