What Causes the Passat's Cooling Fan to Keep Running?
1 Answers
The Passat's cooling fan may keep running due to a damaged thermal switch on the engine radiator, a power failure in the low-voltage live wire of the thermal switch connector, a damaged high-pressure switch on the air conditioning pipeline, or a faulty fan. It is necessary to visit a 4S shop to inspect the specific cause and carry out repairs. Steel Radiators: In this type of radiator, based on its material and performance, it can be further divided into plate-type and column-type. However, when purchasing such radiators, safety issues should be taken into consideration. After all, they are used in automobiles, and poor-quality products can pose significant safety risks, posing threats to both the vehicle and its occupants. To test the radiator's anti-corrosion performance, it is essential to conduct a waterway inspection and not blindly trust exaggerated claims from sellers. Iron and Aluminum Radiators: In previous years, these two types of radiators were relatively widely used. However, due to their numerous performance drawbacks and less obvious advantages compared to steel radiators, they have now been replaced by steel radiators. It is rare to find these two types of radiators on the market today.
