- - - - [mailto:?body=https://blog.argondistributors.co.nz/the-ins-outs-of-engine-cooling-fans-argon](mailto:?body=https://blog.argondistributors.co.nz/the-ins-outs-of-engine-cooling-fans-argon) ![](https://blog.argondistributors.co.nz/hubfs/Blog/HG%20Group%20Crusher%20Radiator%20Fan%20Application%20(5).jpg) In all engines, certain components can directly impact the running and operation of your machine. It's essential to ensure that these components, like engine fans, are always serviced and maintained for your machine's best function and lifetime.  If you need an engine cooling fan NZ wide but aren't sure which model you'll need, keep reading. Today we'll be going over all the ins and outs of engine cooling fans so you can be fully prepared when your fan needs upkeep or replacement.    ## **What are Cooling Fans Used For?** An engine cooling fan or radiator fan is found between the radiator and engine and works continuously to cool your machine's engine down. These fans are crucial when your machine is moving slow or not at all and can't obtain any external airflow to help in its cooling.    There are both mechanical and electric models of these fans. The mechanical models are usually found in modern trucks and older rear-wheel-drive cars. These fans have a built-in clutch, allowing the fan to idle when the engine is cold, saving energy and power. While an electric fan will turn on and off as needed based on the internal temperature of your machine and the engine's computer.    ## **Is Two Better than One?** Some people may believe it's better to run two than one when running electric fans, which can become beneficial when running a large vehicle. Running a dual-fan system means that in the circumstance that one breaks, the other fan is there as backup. It can also help to increase the airflow within your engine during its regular running. While this does mean more space will be needed, it can become a piece of mind and save some time and money if your machine breaks down through its operation.  ![HG Group Crusher with Multi Wing (7)](https://blog.argondistributors.co.nz/hs-fs/hubfs/Blog/HG%20Group%20Crusher%20with%20Multi%20Wing%20(7).jpeg?width=400&name=HG%20Group%20Crusher%20with%20Multi%20Wing%20(7).jpeg) ## **How Does a Cooling Fan Work?** Your mechanical fan will be connected directly to the engine by drive pulleys. The senses that recognise when the fan should and shouldn't run are controlled through a thermal fan clutch. The radiator fan will then turn on when the engine starts to run at a higher temperature.   Your electric fan is used to boost the performance of your engine and work on decreasing the emission waste. A coolant sensor activates the temperature sensors in these models through the computer. This coolant sensor is in charge of monitoring the temperature of your engine's coolant. If the temperature of the coolant rises in temperature, the sensor will then alert the cooling fan.  ![HG Group Crusher Radiator Fan Application (1)](https://blog.argondistributors.co.nz/hs-fs/hubfs/Blog/HG%20Group%20Crusher%20Radiator%20Fan%20Application%20(1).jpeg?width=400&name=HG%20Group%20Crusher%20Radiator%20Fan%20Application%20(1).jpeg) ## **Contact Argon for the Best Quality Fans** If you want to learn more about our engine cooling fans, contact [our friendly team at Argon](https://argondistributors.co.nz/contact/) to find the best solution for your business.
