Common causes of these coolant leaks include radiator damage, worn hoses, and water pump failures, with radiator corrosion and aging being significant concerns. To detect leaks promptly, owners are advised to regularly check for puddles or stains under the vehicle, monitor the temperature gauge for unusual readings, and visually inspect for leaks.
