You may find that you will need a dual fan setup to cover the radiator … When replacing these and turn it, the fan blade should free wheel, if you cannot turn the fan blade the However, a broken fan could be confused with a fan that simply has not kicked in yet. not in use, allowing the engine to work more efficiently while decreasing fan noise. During cooler weather you may only find the low speed fan works however in warmer weather when the radiator can't disperse its heat so well the high speed fan operates as well. engine temperature is rising above normal limits, a signal is sent to close the Do Dual Electric Fans Work in a 1996 V8 Jeep Cherokee? I replaced water pump and radiator and coolant temp sensor. All aspects of the cooling system, from the fan to the thermostat to the radiator hoses, must be in good operating condition to ensure that the engine does not overheat, which can lead to a costly repair bill. Electric Cooling Fans Most modern vehicles use electric cooling fans to help pull air through the radiator so that it can keep the engine cool.
