What is the reason for the radiator fan of Chery QQ308 not working?
1 Answers
The water temperature meets the requirements, but the car radiator fan still does not work, which may indicate a fault in the fan relay. The function of the radiator fan: The fan's role is to draw in air, allowing it to pass through the radiator fins and carry away heat. Therefore, the closer the fan blades are to the radiator, the better. Considering the deformation and displacement of components after installation, a distance of about 10mm is generally maintained between the fan blades and the radiator to prevent contact. Operating conditions of the radiator fan: The vehicle's radiator fan is activated when the coolant in the radiator reaches a certain temperature, controlled by a thermal-sensitive switch. When the coolant temperature rises further, the thermal-sensitive switch increases the fan's speed. The car radiator fan cannot be manually controlled; it is governed by the thermal-sensitive switch on the radiator.
