How to FIX Bad Car Radiator Fan Problem is Weak, Gnewscar.com – Engine conditions with ideal working temperatures must always be maintained in every Toyota car. But what if suddenly the engine conditions are too hot to overheat? That means there’s a problem. One of them is the radiator fan is weak. Actually there are characteristics of a weak radiator fan that must be repaired immediately. Usually this happens on cars that are not well maintained or on old age vehicles.
You should not silence this problem. A weak radiator fan can cause a variety of other problems. Therefore, let’s look at the characteristics of weak radiator fan and fix this bad problem.
Characteristics Bad Car Radiator Fan and Weak
There are various signs that you can feel if the radiator fan starts to go weak. The radiator fan itself had developments in its time. The old-fashioned radiator fan is directly connected to the engine pulley using a V Belt. At this time, the radiator fan is driven by an electric motor so that the car’s power efficiency is better. So what if the radiator fan is bad and already weak? You can find out here.
1. Engine Overheated
Engine overheating is one of the most obvious signs of a weak radiator fan. Overheat occurs because the engine cooling system is completely unable to reduce the engine temperature which continues to increase. One of the main reasons, of course, is a weak fan blowing. Finally the radiator cooling process becomes even longer.
Even though the engine temperature should not continue to increase even though it is working.

2. AC is not cold enough
AC is one of the mandatory features in the car. Its main task is to make the cabin temperature cooler so that the passengers feel comfortable throughout the journey. But what if the AC is not cold enough?
Many people think that this problem is caused by the AC freon starting to run out. It’s not just that though. The air conditioner is not cold enough, it can also be caused by the radiator fan starting to weaken. The radiator fan is useful for cooling the AC condenser. The speed of the radiator fan can affect the temperature of the freon after it is cooled.
If the fan blowing is weak, then automatically, the freon cooling performance becomes less than optimal. This is what makes the air conditioner blowing less cold even though the setting is already the highest and there is a knocking or tickling sound.

3. Tickling Machine
Back to the engine, it turns out that there is one more characteristic when the radiator fan is weak. Engine knocking is a term for engine knocking, this problem occurs because there is a pre-ignition. When this pre-ignition occurs, it means that the engine temperature is too high. This condition triggers the occurrence of premature combustion causing a knocking or noisy sound.
How to Detect a Weak Car Radiator Fan
You can detect a radiator fan that is starting to weaken in this way:
- Turn on the car then turn on the AC.
- Now get out of the car and open the hood.
- In this condition, the cooling fan can only run at certain intervals. That is, the fan is not always on. In addition, the fan gust is also not too big.
- Now turn the AC temperature selector to the coldest level, then observe the fan performance.
- The fan rotation should be longer, faster, and the wind gusts are big enough
- If that doesn’t happen, it means there’s a problem with your radiator fan.
To find out how much the fan blows can’t be done with the sense of taste because this is relative. To be more accurate, you should familiarize yourself with doing this check. So when the fan is weak, you can feel that the fan blowing is not as strong as usual.
Also check the sound when the fan is spinning
Sometimes, fans like noise. This sound can be caused by worn out fan shafts or because the fan blades touch the fan frame. The sound of a normal fan, it was smooth like a rotating electric motor. If it is accompanied by the sound of friction between two objects, then your car’s radiator fan has a problem. Immediately to the workshop for repair steps.
Checking the fan electrical circuit is equally important
Apart from the direct fan, this problem can also attack the fan’s electrical circuit. You can do a simple check by naked eye. You do this by looking at the fuse or fuse in the fuse box. Usually two or more cars have three fuses for one fan. Make sure all fan fuses are connected and still good. Thus the article about the causes of a weak car radiator fan.
