Radiator fan not working symptoms

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.

What happens when radiator fan stops 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.

Can a car run without radiator 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.

Can you drive with a bad radiator fan?

You should not drive a car without a radiator cooling fan working, your car will get hot very quickly, maybe your fan belt is broken causing the water pump to stop pumping coolant to circulate around the engine block.

How do I check if my radiator fan is working?

A simple way to check if the radiator fan is working is to start your engine and turn the air-conditioning system (A/C) to the maximum speed. If the fan is spinning, then it means that the fan motor, fuse, wiring, and relay are all working properly.

Can a bad thermostat cause fan not to come on?

If the thermostat is stuck open (allowing coolant to flow) it can cause the engine to run cooler than normal so obviously the fan wouldn't come on.....but not like the engine/coolant can be running too hot and the thermostat somehow effects the sensor reading or operation of the fan.

Should radiator fan turn on when AC is on?

When the AC compressor is activated, it is actually expected that the radiator fan runs. For instance, the radiator fan is needed when the temperature sensor of the cooling fluid in the lower tank reaches approximately 212F.

How far can you drive a car with no radiator?

From a cold start, you could probably go for at least 1km, maybe 2. If you were driving and the radiator was shot and got emptied, I doubt you can go 400m. If you do that, start the engine and drive straight off, accelerate gently up to 40-50km/h, put on neutral and let it coast.

Can a broken radiator fan cause overheating?

Engine overheating: A bad radiator fan can cause the engine to overheat, especially at low speeds. If your car starts overheating, pull off the road as quickly as you safely can and turn off the engine. An overheated engine can quickly get ruined and lead to expensive repair bills.

What does a bad radiator fan sound like?

In some cases, when your radiator cooling fan clutch fails, it will develop a whirring or clicking noise. The noise could result from a bearing that is out of place or a bent fan blade that is touching other components.

How long do radiator fans last?

In most cases, a properly maintained radiator fan will last between eight and ten years. When the radiator fan fails, it should be replaced as soon as possible.

How much does it cost to replace a radiator fan?

The average radiator fan replacement cost is typically between $550 and $650. In many cases, the radiator fan will cost around $400 to $450, while the labor adds $150 to $200. However, some vehicles can be more expensive, depending on the design.

Should both fans run constantly?

It can be normal for the cooling fans to run constantly under certain conditions. If the car is hot enough, they may be barely keeping up with demand and stay on. Also, most cars will run the fans at a high speed if the A/C is turned on.
