How can you tell if your radiator fan is bad?

How can you tell if your radiator fan is bad?

These are the most common signs of a faulty radiator fan assembly in need of replacement:

1. Engine Overheating. When the radiator fan isn’t functioning properly, it is not able to adequately cool down the car’s engine.
2. Air Conditioner Function Diminished.
3. Loud Noise Coming From Radiator Fan.

When should radiator fan come on?

Most fans should come on when the coolant reaches about 200 to 230 degrees. If the fan does not come on, something in the control circuit is defective.

Can I drive with one radiator fan not working?

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.

What can cause a radiator fan not to work?

The most common reasons a radiator fan is not working are luckily due to a blown fuse, bad relay, or a broken wire. It can also be caused by a faulty coolant temp sensor, low coolant level or the fan itself can be damaged.

What happens if car radiator fan is not working?

What happens if the cooling fan stops working? If your cooling fan stops working, your engine could overheat. This could cause damage to your engine parts. It’s a serious issue and needs to be looked at by a garage.

Temperature will often determine the time that a radiator fan starts up. A temperature-sensitive switch functions to turn the fan on and off periodically. Radiator fans are designed to start when the temperature of the engine coolant reaches around 200 degrees Fahrenheit.

Why is my radiator fan not running?

What happens when your radiator fan stops working?

What happens when a radiator fan stops working? It will cause a loud whirring noise and a stuck open thermostat (which will not allow the engine to reach the average operating temperature). A lousy radiator cooling fan could cause a blown circuit fuse, a malfunctioning relay, and engine overheating.

Can a bad thermostat cause radiator fan not to work?

Broken Thermostat Thermostats are known to go bad and cause all sorts of cooling issues. If this thermostat doesn’t open when the engine reaches the working temperature, the coolant will stay inside the engine block and the engine will start to overheat. This will result in the radiator fan not working.
