Has your vehicle been running a little bit too hot the past few days? When youíve noticed that you tend to overheat when sitting in traffic or going uphill, then you might want to consider getting an auxiliary fan to help out your carís radiator. This is a relatively inexpensive add-on that is quite easy to install, but you have to make sure that you get a model thatís perfect for your vehicle. Let us show you how.
Why do you overheat?
Your carís radiator relies on the airflow coming in from your front grille to cool down your engine. When youíre driving at slower speeds, going uphill, or when youíre stuck in heavy traffic, your engine would be running at a lower RPM. As such, your belt-driven fan wonít be turning fast enough to push in enough air to cool down your radiator. An auxiliary fan will solve this problem since it will be blowing in air when you need it the most.
What to look for in an auxiliary fan?
Typical auxiliary fans tend to range somewhere between $100 - $150, and higher end models can go as high as $500 or more. We recommend that you look for a fan that doesnít have full shrouds or unnecessary panels that could block air from reaching your radiator. Manually controlled auxiliary fans tend to be cheaper than automatic ones, but you wouldnít want to be bothered turning a fan on and off so itís better to spend a little bit more money and get the automatic fan instead. This is a very simple device, so you wonít have any problems when you get an OEM replacement, especially when itís designed for your vehicleís particular make and model. Finally, we strongly urge you to install it yourself. Installing an auxiliary fan on your own should be pretty much straightforward, so it wouldnít make sense to waste money by hiring a mechanic to help you out.
