How does an engine cooling fan work in a car?
The engine cooling fan is designed to move air through the radiator when the vehicle is at slower speeds or stopped. This air flow removes heat from the coolant created by the engine using the radiator as a conductor.
Why is my engine cooling fan not working?
Your engine cooling fan, only runs when needed to help cool the engine. So, a engine cooling fan, relay or control circuit failure is bad news. Because, it can allow the engine to overheat. The engine coolant sensor or a separate engine temperature switch, is used to monitor engine temperature.
Can a failed radiator fan cause a car to overheat?
The most common symptom of a failed radiator fan is that the car is overheating on idle or at lower speeds because at higher speeds the car doesn’t need the use of the radiator fan. You should check if the radiator fan is spinning on full power when the thermostat is fully opened and the car engine is hot or while it’s overheating.
What happens when a condenser fan motor overheats?
Most condenser fan motors have been designed to operate at temperatures up to around 150F. When there is something wrong with the fan motor, it can overheat and cause problems with the HVAC system. What Does a Condenser Fan Motor Do? A condenser fan motor is part of your HVAC system that is located within the condensing unit.

Can a bad fan relay cause an engine to overheat?
However, a bad cooling fan relay isn’t the only culprit for excessively high engine temperatures. Many other issues can cause the engine to run hot or overheat. Rather than uncommonly high engine temps, the driver may notice that the cooling fans have stopped running.
When do you turn on the cooling fan?
Once the coolant temperature sensor detects that the engine temperature has exceeded acceptable levels, the cooling fans will be activated to keep the engine cool. Many vehicles come equipped with cooling fans that operate on more than one speed setting.
