To be able to cool the engine effectively, the radiator needs a fan to create a steady flow of air passing through the core and over the engine to dissipate engine heat. But this doesn't mean the radiator will stop working without a radiator fan; there are actually instances when the fan is automatically turned off by the vehicle's computer because there's already enough air flowing past the front grille into the engine bay. Unfortunately, that's often not the case.
At one point after your engine starts running, the engine block will inevitably become too hot for the radiator to handle. This usually happens during traffic jams and low-speed driving when there's not enough air coming in through the grille to cool the radiator's fins. In order to work, the radiator fan is driven by either a drive belt or an electric motor, depending on the type of vehicle. A belt-driven fan has a viscous drive clutch controlling its speed, while a motor-driven fan is usually controlled by a thermostatic switch and the vehicle's engine control unit or ECU.
To make sure the car radiator fan is always in top working condition, clean it on a regular basis. You don't need to pay a mechanic to do this. You just need some pipe cleaners, rags, degreaser, sockets, and a ratchet. To start off, remove the fan from the compartment by using sockets and a ratchet to remove the mounting bolts. Then, carefully pull off the connecting wire and finally pull the fan up and out from the engine bay. If you take a closer look at the fan, you'll probably see traces of grime and dirt. To remove these, rub a rag dipped in degreaser across the fan blades. For hard-to-reach areas, use a pipe cleaner soaked in a cleaning solution. Let it dry first before placing it back on its mount.
Radiator fans are generally sturdy and dependable. However, over time, the blades could become more prone to bending, cracking, and wearing out. When the fan for your ride's radiator gets damaged, you have to replace it immediately to minimize the risk of overheating. When looking for a replacement fan, look for something with bigger blades but which still matches your car's specs. Such a fan would funnel more air to dissipate the heat from the radiator and under the hood. Aside from that, it would be best to get a fan that already comes with all the mounting hardware so you can install it easily.
