What controls the electric cooling fan?
Most cars today have an electric cooling fan that is controlled by the computer or a thermal fan switch and a relay. Electric fans often are mounted behind the radiator, and sometimes in the front.
How do I know if my radiator fan fuse is bad?
These are the most common signs of a faulty radiator fan assembly in need of replacement:
- Engine Overheating. When the radiator fan isn’t functioning properly, it is not able to adequately cool down the car’s engine.
- Air Conditioner Function Diminished.
- Loud Noise Coming From Radiator Fan.
Can you drive without cooling fan?
Yes, technically your engine does not need a cooling fan to operate. If the radiator does not have cool air blowing on it constantly, it will overheat eventually, so you’d need the perfect combination of weather and traffic to drive effectively without a radiator fan.
Why is my radiator fan fuse blowing?
A blown cooling fan circuit fuse is another symptom of a potential problem with the cooling fan motors. If the motors fail or surge, they may cause the fuse to blow in order to protect the rest of the system from any sort of damage due to electrical surges.
Should fan be on auto or on?
Keeping your fan on AUTO is the most energy-efficient option. The fan only runs when the system is on and not continuously. There is better dehumidification in your home during the summer months. When your fan is set to AUTO, moisture from cold cooling coils can drip and be drained outside.
What causes a fuse to blow on a cooling fan?
3. Blown fuse. A blown cooling fan circuit fuse is another symptom of a potential problem with the cooling fan motors. If the motors fail or surge, they may cause the fuse to blow in order to protect the rest of the system from any sort of damage due to electrical surges.
What kind of motor does a cooling fan use?
It is the job of the cooling fans to provide that air flow, and they do so using electric motors. The electric motors found on many cooling fans are not much different than regular industrial use electric motors, and are often a serviceable or replaceable component of the cooling fan assembly.
Where are the cooling fans on a car?
The cooling fans are mounted on the radiator and work to pull air through the radiator fans to keep the engine cool, especially during idle and low speeds, where air flow through the radiator is significantly less than at road speeds.
What happens when you disable the cooling fan?
The cooling fans are thermostatic and are designed to come on once a certain temperature is reached, or certain conditions are met. If the cooling fan motors fail, and disable the fans, the engine temperature will continue to climb until the engine overheats.
