The radiator is a primary component of a vehicle’s cooling system. It circulates coolant fluid from the water pump to the engine, keeping the car from overheating. To maintain your cooling system, it is important that the radiator is working properly and efficiently removes the heat from the engine. So, if you are 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 rest of the cooling system will be affected and may need to be replaced. Because a leaking radiator will cause the engine to not get the proper amount of coolant, if ignored long enough, the engine will overheat, leading to costly repairs. From a safety standpoint, there is a slight safety risk, because an overheated engine might leave you stranded. There is high environmental impact because leaking coolant is harmful to children, pets and other animals.
