Engine Cooling Fan: Operation

Radiator fan operates when coolant temperature sensor verifies coolant temperature has reached predetermined temperature (depending on model). On reaching specified temperature, coolant temperature sensor contacts close, allowing current flow to radiator fan relay and fan motor. Fan shuts off when coolant temperature drops to predetermined value (depending on model).

Radiator fan should always operate when A/C compressor clutch is engaged. On models with dual electric fans (except Avenger, Sebring & Talon), fans operate through a common relay and are activated at same time.
