Does the coolant temp sensor on a 2002 cherokee control radiator fan relay?

Yes, the coolant temperature sensor on a 2002 Cherokee controls the radiator fan relay. The coolant temperature sensor is located in the cylinder head and measures the temperature of the engine coolant. When the coolant temperature reaches a certain level, the sensor sends a signal to the relay, which then turns on the radiator fan. The fan draws air through the radiator, which helps to cool the engine.
