The Jeep Grand Cherokee Radiator Fan Relay controls the power supply that turns the cooling fan on and off to give the radiator extra airflow. The Radiator Fan Relay receives a signal when engine coolant reaches a pre-set temperature or A/C is switched on the internal contacts close so 12-volt current goes through to the electric fan motor mounted in the shroud assembly. When the temperature of the coolant drops below the switch point, the Radiator Fan Relay opens the circuit stopping the fan and saving energy. To make sure that enough air moves through the fins and tubes of the radiator, the component through this cycling of the fan during slow driving or idling prevents heat build-up enough to cause the engine in Jeep Grand Cherokee to overheat. The Radiator Fan Relay supports the electric fan that is applied on nearly all modern vehicles and not the old style thermal clutch type mechanical belt driven fan. Jeep Grand Cherokee models do not have any alternative styles or variations in materials for the Radiator Fan Relay, so this description pertains to one confirmed configuration in the Jeep Grand Cherokee range.
