Radiator Cooling Fans
Cooling Fan Clutch Step 2 - An electric cooling fan is used primarily to boost engine performance and cut down on emissions. These fans are featured in both front and rear wheel drive vehicles and are activated by a coolant sensor via the computer. Using a sensor the computer detects that the engine temperature is rising above normal limits, a signal is sent to close the fan control relay which is protected by a circuit fuse. When replacing these cooling fans match the failed unit with the new cooling fan.
