The radiator fan or engine cooling fan is designed to allow the movement of air through the radiator when the vehicle is stationary or is at a slower speed. The airflow removes heat from the engine coolant generated by the vehicle’s engine utilizing the radiator as the conductor. The radiator fan or engine cooling fan is designed to allow the movement of air through the radiator when the vehicle is stationary or is at a slower speed.

Basic Things About Radiator Fan

An engine cooling fan serves its main purpose in cooling temperature-controlled to only run when it is necessary. Since we all knew the purpose and function of a radiator fan, the different types of radiator fan, and the history of the radiator fan, we should now decipher and figure out how the car radiator fan works.  

The Process of how Radiator Fan Works

Step 1- There are mainly two types of the radiator fan. Mechanical and electrical radiator fans. The mechanical fan is really connected to the engine which is directed by drive pulleys. This type of radiator fan is governed by the thermal fan clutch which senses the heat in the radiator. After the heat temperature has been detected, the radiator fan will turn on when the engine is running at an increased temperature. The thermo-reactive clutches utilized this type of radiator fan which are built to disengaged when not in use and becomes connected through the help of grease that expands when heated.  This type of unit utilizes shaft bearings and seals in order to retain lubricant. The clutches are said to be typically bolted to the water pump to the engine. How Does A Radiator Fan Work?

How can the radiator fan fail?

The clutch radiator fan may have the chance of failure while being driven. The primary way of failing that this kind of radiator fan is by locking up. This would directly influence and cause whirring and loud sounds with poor mileage. The second way of radiator fan failure is by leaking silicone grease. This will cause the fan to fail and will pull air through the radiator. This will make the cooling of the air to be quite impossible. Step 2 – The electric radiator cooling fan is the second type of fan we need to discuss. This is mainly utilized to boost the performance of the engine and achieve a reduced emission waste and engine exhaust. This type of cooling fan is utilized both in the rear and front-wheel drive of the cars. This type of cooling fan is activated by a coolant sensor through a computer. The coolant sensor is the one in charge of monitoring the engine’s coolant’s temperature. If there is a coolant sludge, then this is a sign of the cooling fan radiator failing and might need an urgent replacement. Through the sensor temperature detection is possible. It can also alert the radiator if the coolant is above the normal levels. Keep this in mind, a signal will be immediately sent to the cooling fan control system relay which is protected by a specific circuit fuse. How Does A Radiator Fan Work? That is the overview of how the radiator fan works. It is extremely important that car owners do understand these parts of the car. Although it may be too much to acquire repair skills, at least the driver now understands what is happening in the car, the parts, and how they work together to run the vehicle smoothly.

Learning about car parts (radiator fan) makes you a responsible driver and owner.

Learning things like this will surely make you a better car owner. You see, repairs can be expensive. Understanding how cars work will allow you to make better and more informed decisions regarding your vehicles. How Does A Radiator Fan Work?
