Hit a mailbox car got hot fan won’t turn on

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! It sounds like this ride has been quite the Journey! See what I did there? Please forgive me. It sounds like the fan may have been damaged when that mailbox ran into your car. The cooling fan cools the coolant as it runs through the fins of the radiator. If the fan isn't turning on when prompted, it means there's a fault in the fan itself, the coolant temperature sensor, or the wiring. Do not drive the car. Have it towed to a professional and have them run a diagnostic. If you have any other questions, please call us at 877-913-1554! We'll gladly find you a certified RepairPal shop in your area!
