Coolant seepage at the tanks or core, a coolant level that keeps dropping, or a temperature gauge that climbs can all be signs of a radiator problem. Before you replace the radiator, rule out the radiator cap, hoses, thermostat and water pump as the source of the leak or overheating. Check coolant only with the engine off and cool. Each engine's cooling system runs on one radiator, and this listing is that single unit.
