The radiator is a primary component of your vehicle’s cooling system. It circulates coolant from the water pump to the engine, keeping the car from overheating. To maintain your cooling system, it’s important the radiator efficiently removes heat from the engine. If your car is overheating and coolant is not moving effectively throughout the system, have your service advisor take a look at your radiator. Without a functioning radiator, the cooling system will be affected and may need to be replaced. A leaking radiator will not allow the engine to get the proper amount of coolant. If ignored long enough, the engine will overheat, leading to costly repairs. From a safety standpoint there’s a slight risk, because an overheated engine could leave you stranded. There’s high environmental impact, because leaking coolant is harmful to children, pets and other animals.
