Why does the fan of the Discovery Sport keep running after parking?

[AdrianaFitz]

The fan in the car serves a cooling function. Therefore, when the coolant temperature is too high after parking, the vehicle's computer will automatically calculate the fan speed and duration. The higher the coolant temperature, the longer the fan runs, which helps protect the engine—this is a normal phenomenon. However, if the fan continues to run for an excessively long time even after the engine temperature has dropped, it might be due to a poor electrical connection. In such cases, you can try disconnecting the fan's wiring harness to cut off power separately. Other possible reasons: The coolant temperature sensor may be damaged, or the fan relay contacts might be stuck. In these situations, simply visit a repair shop to replace the faulty component. Check if the coolant temperature meets the requirement: Most modern car radiator fans operate based on electronic temperature control. Therefore, the fan typically starts running only when the coolant reaches the required temperature. If the temperature is too low, the radiator fan won't operate. Hence, if the car radiator fan fails to rotate, the first step is to check whether the coolant temperature meets the specified requirement.
