What is the reason why the radiator fan of Haval H6 does not rotate?
2 Answers
Car cooling fan does not rotate for the following reasons: Poor water temperature control: It may be due to poor water temperature control. Generally, at lower temperatures, the water temperature sensor cannot influence the generator to start the fan, thus affecting the rotation of the car cooling fan. Therefore, it is necessary to properly control the water temperature to meet the specified requirements. Small current inside the transformer: The adjustment of fan speed relies on the transformer. So, when the current inside the transformer is small or there is an internal fault, it will affect the operation of the cooling fan. Therefore, it is necessary to check whether the current flowing through the transformer is within the normal range and whether this part is functioning normally.
Last time my Haval H6 also had the radiator fan suddenly stop working, which made me really nervous. I later figured out that the most common causes are either the fan motor burning out or a blown fuse. That car had been running for over five years, so aging wires causing poor contact was also very likely, especially when the connector loosened and the fan would stop. If the coolant temperature sensor is broken, the car simply doesn't know it needs cooling, so naturally the fan won't move. A faulty relay is also quite troublesome as it can't control the current flow. At the time, I first checked the fuse box myself, located on the left side of the engine bay, and tried replacing it with the same model. But if the problem is more complicated, like a short circuit or control module failure, it's best to head to the repair shop immediately. After all, if the fan doesn't work and the engine overheats, the consequences can be serious. The mechanic told me prolonged high temperatures can damage the engine head gasket, making repairs even more expensive.
