If the radiator fan won't work, it could be the clutch is bad. Radiator fans on the large V8's are supposed to "freewheel" if the engine is cold, and engage when the engine warms up. If the clutch isn't engaging, get a new one. It'a a simple replacment process, just pull the top half of the radiator fan shroud, pull the 4 bolts that hold the clutch to the water pump, then replace clutch.
the first thing you should do is check to see if you have enough coolant in your car. it cools down the engine. the other this is your radiator fan may be broken is does this same thing the fan in the computer does... cools it off.
Replace the fan clutch that is on the front of the engine.
because the fan cools the engine...
cools the engine. without a fan, the car will overheat and the coolant will boil. the fan controls this from happening by cooling the coolant as it passes through the radiator.
If your engine is overheating rapidly it could be because your fan belt is broken If the fan belt is broken, your car will over heat.
It is an engine cooling fan that cools the fluid as it passes through the radiator.
Broken engine fan temp sensor.
so that it cools the engine down
I believe it turns on and off the fan (1 out of 2) that cools the engine according to the temperature it's at. If it doesn't work the engine may not know to turn the fan on and the engine could overheat. Here's a tip. When you turn on your A/C or Heater, both fans come on. The A/C cooling fan and the Engine Cooling fan.
make sure that u have water in ur radiator and also check that the fan that cools the engine is working.
There isn't anything that cools the fan the fan is only on long enough to cool your motor then the air as you drive cools the fan
If this is the fan that cools the engine it will run for a while after the car is switched off. If its the internal heater then I haven't a clue.
