Car Radiator Heating Up? 5 Radiator Fan Problems That You Need To Know

We can hardly imagine life without cars. As much as we depend on them, we should realize that much harmony and symbiosis. Goes inside the car machinery to keep it going.

Since the car mechanism works by Converting one type of energy to another, heat is an evident result.

It is the radiator fan that keeps the radiator from heating itself up and wearing out.

In fact, Heat is also one of the biggest reasons for car engines to stop.

However, there can be times when you can face radiator fan problems.

The fan could simply stop working or work inefficiently.

There are several such problems that you may experience. The great news is that they are easy to fix and You need not spend a fortune on them.

How You Can Be Certain about Radiator Fan Not Working

It is very easy to assume that your car’s radiator fan is defunct.

But, the only surest way to check it is by actually looking for the fan’s sound.

All you have to do is lift the engine Hood and listen closely for the sound of the fan.

The best of modern cars have very quiet engines and so, It may not be easy to figure out the sound while you are inside the car.

Make sure that you don’t skip this check to ensure that the radiator fan is not working.

Now, let’s proceed to see what these 5 problems are:


5 Common Radiator Fan Problems

Here are 5 common problems that may be ailing your car’s radiator fan,

These make the car radiator fan defunct or inefficient:

1. A Bad Fuse

It is a very common issue that results in a failure of the radiator fan: the fuse will burn off or simply fall off.

You’re going to have to check the owner’s manual to figure out exactly where you can find the fuse, but once you’ve found it, it’s an easy task.

You will need to replace the radiator fan fuse in case it absent or doesn’t work.

Know, if there’s something electrical in your vehicle that doesn’t work, your first checkpoint is the fuse.

2. Dead Wires

If you see the engine heating but the radiator fan isn’t, the fan wires might be the culprit.

Simply unplug both the negative and the positive wires.

The normal direct current to be put out is 12v (approx) (approx.).

Take a voltmeter and check the presence of the current.

If there is none in one or both of those, you’ll need to replace it.
You will be able to find the fan relay under the hood.

Check the current from the relay to the fan.

This is where the current needs to flow. If there is a voltage present, the reason for the failure of the radiator fan is a fault in the fan.

It’s the fan that you’re going to need to replace.

3. Broke Fan Clutch

The fan clutch is responsible for attaching the radiator fan to the engine and making it work.

If this clutch is broken, the fan won’t work.

If you can’t find any other issues with the fan of the radiator, the clutch is most likely the cause.


4. Inadequate Coolant Level

Inadequate coolant levels in the engine can also cause a failure of the fan.

Only look at the coolant tank and check if the level is up to the maximum mark required.

If you wouldn’t, just fill it up to the mark and you’re going to be good to go.

In fact, this is one of the handiest maintenance tips that will help you keep both the engine and the cooling/heating system in good condition.

5. Defunct Temperature Sensor

Radiator Fan Problems due to defunct temperature sensor

The temperature sensor is a mechanism that decides when the fan of the radiator has to start acting.

It is done by reading the temperature of the cooling system.

If this sensor is out of order, the fan may not be able to start working. You are likely to identify this sensor on the cover of the thermostat.

You can try and disconnect the wires and reconnect them to the sensor, the chances are it will work. If not, you’re going to have to have it replaced.
