Auxiliary Fan Switch 75-82C

The auxiliary fan in your vehicle serves an extremely important role. When your car reaches temperatures that may be hazardous to your engine, the auxiliary fan moves air through the radiator to provide better cooling. Usually activated during times of stationary vehicle operation, it supplements the air usually driven through the radiator by driving down the road.

If your fan is not running and the motor has tested good, your problem is most likely the fan switch. The fan switch sends the signal to the control unit to turn the fan on and cool off your vehicle. This is done at certain temperature ranges and helps to keep your engine from experiencing damaging heat. A simple, low cost replacement that will keep your engine safe.

During the change, you will more than likely lose a fair amount of coolant. Browse Euromotiv's site to get the proper, factory approved coolant to keep everything at the proper temperature.
