Radiator Cooling FanAn electric radiator cooling fan, operating independently of the engine, is controlled by a thermoswitch located in the bottom of the radiator. At high coolant temperatures, the switch closes to start the cooling fan. The cooling fan is wired directly to the battery. Any time the coolant temperature is excessive, the fan will start and continue to run until coolant temperature is in the correct range. On models with air conditioning, high refrigerant pressure can also activate the cooling fan. On some models with gasoline engines, a cooling fan after-run system, operated by a control unit on the fuse/relay panel, runs the cooling fan for as long as 15 minutes after the engine is shut off, as a guard against starting problems which may be caused by high engine compartment temperatures. |
