No. It is an electric fan with a thermostat.
The engine temperature sensor is located next to where the upper radiator hose attaches to the engine. The computer uses that sensor to decide when to actuate the radiator fan relays and turn the fans on.The engine temperature sensor is located next to where the upper radiator hose attaches to the engine.

If the question is about the motor fan or engine fan, the main function of this fan is cooling the radiator of the engine which in turn is cooling the water circulating inside the engine unto the radiator and back. This keeps the engine at a fairly operable temperature without overheating and damaging damaging its parts.
The fan should turn off after the engine is shut off. If it stays on, the radiator fan relay has failed.
unplug the coolant sensor and turn on the ignition without starting the engine. The fan will run.
That is the fan cooling the liquid in the radiator to keep the engine from over heating.
yes
Usually ECT or engine coolant temp sensor. That's what tells the engine computer to turn on the fans.
Yes, when the a/c is used the engine works harder which rises the temp of the engine then turn the fans on to cool the radiator.
radiator fan is supposed to turn on before over heating to draw more air thru radiator and over engine to assist with cooling if fan is not turning on soon enuff , you need a new lower temp fan switch
Radiator fan could be bad, fan relay bad, fuse blown. Also if your ECT (engine coolant temperature) sensor is bad the ECM (computer) won't know to tell the fan to turn on.
no the radiator fan will only run when the engine is up to temp and needs to cool back down usually 180 to 220 degrees
Possibly a faulty coolant temperature sensor. It could also be a bad fan relay, bad ground at the computer, or faulty wiring of the coolant fan circuit. How about a bad water pump. I don't think in this instance the water pump would be the issue. The radiator fan is designed to cycle on and off depending on the temperature of the coolant circulating in the engine. The water pump is what is responsible for that circulation; from the engine, to the radiator and back again. If the water pump was not functioning properly, the coolant would not be able to circulate from the engine to the radiator, and the engine would overheat. If this were the case, the temperature sensor in the block would signal the computer to run the radiator fan continuously in order to cool the engine. The question being asked is why does the radiator fan turn off, even when the engine is hot? Not why does my radiator fan never turn off?
