There are a number of different fans located in your Mercedes-Benz vehicle. These are important for the functionality and operation of your vehicle, as your car will generate a lot of heat when you're out on the road. The radiator cooling fan is an important fan to keep an eye on. The fan is mounted on your radiator and it helps pull air through to keep your engine cool. Cooling fans keep and regulate air flow so that your engine doesn't overheat. Over time, cooling fans and other fans under the hood of your vehicle have the potential to wear out. There are some symptoms to look out for in this case. The most obvious thing is the cooling fan simply not coming on. The cooling fan motor can burn out and prevent the blades from spinning. You also could notice your vehicle overheating in the case of a cooling fan failing. If you're in need of a new fan or fan kit, be sure to get an OEM one for your Mercedes-Benz here on our site.
