Car radiator fan units are part of the cars cooling system and are either controlled by a thermostatic switch or by the vehicles ECU. The purpose of the fan is to help blow cooler air through the radiator when the coolant levels rise above a certain temperature. You are likely to notice this on occasions when you are stuck in traffic and there is no cool air moving through the grill to help cool the coolant system. Over time these begin to wear, with the likeliness of impacts from stones and other contaminants.With these direct replacement units, changing your fan unit has never been so simple.
