What Causes the Engine Fan Not to Rotate and the Engine Temperature to Be Too High?

[AdrianaLynn]

The engine fan not rotating and the engine temperature being too high is caused by a ground fault at the fan connector in the engine cooling system. Function of the Cooling Fan: The car fan is controlled by a thermostat. The engine fan exists to prevent the engine water temperature from becoming too high. It consists of a sensor, an electric fan, a chip, and other components. When the engine water temperature exceeds 90 degrees, the sensor receives the temperature signal and activates the fan to lower the water temperature. Once the water temperature drops to the set level, the fan stops working. Cooling Fan Replacement Method: Open the car's engine hood, remove the intake pipe located above the cooling fan, and then use professional tools to unscrew the four screws on the fan bracket to remove the fan. Finally, correctly install the new cooling fan onto the new fan bracket and reattach the intake pipe.
