To stop the engine from overheating, we take the help of coolants that flow through a radiator into the engine. The radiator’s job is to keep the coolant cool so that when it returns back into the engine, it is able to absorb more heat. A radiator fan is thus used to keep the temperature of the coolant in check. Thus, it has an important job.
