Electric radiator cooling fans can be purchased new from many online retailers, such as Summit or JEGS, or from secondhand auto parts communities such as O'Reilly Auto Parts. While online retailers sell the fans directly from the manufacturer, websites like O'Reilly Auto Parts allow users to buy new or used items from advertisements placed by other users.
Radiators almost always come with some sort of fan to keep the temperature of the unit as low as possible while the vehicle is in use. Older engines used mechanical fans, but today it is most common for engines to utilize electric fans that are wired directly to the vehicle's power supply. The fans are susceptible to wear and tear, which means that many vehicle owners end up buying either new or used fans directly from their vehicle manufacturer, from a local mechanic shop, or from online retailers and auto parts traders.
Some online resources where users can buy new electric radiator cooling fans directly from the website are Speed Unlimited and JEGS. Used fans can be bought from classified ads on auto trader websites like O'Reilly Auto Parts. Because fans come in different sizes and either push or pull air, vehicle owners who do not know what kind of fan to purchase should consult a local mechanic.
