At what temperature does the Roewe 550's fan start working?

[StLaura]

The cooling fan of the Roewe 550s starts operating when the water temperature reaches 95 degrees Celsius. Here is some information about the automotive cooling system: 1. The automotive cooling system is divided into a major cycle and a minor cycle. When the engine is cold and at a low temperature, it initially operates in the minor cycle to quickly reach the working temperature of 90°C. Once the temperature rises to the normal range, the thermostat opens, and the major cycle begins. The coolant then passes through the radiator, causing the temperature to drop by 1°C to 2°C. 2. When the temperature rises again to 90°C–94°C, the fan starts operating at low speed to dissipate heat. If the temperature further increases to 96°C–102°C, the fan switches to high-speed operation for enhanced cooling. This entire process takes about 15–20 minutes at idle, and even less time during normal driving. Therefore, a trip of 30–50 kilometers is sufficient. In winter, if the vehicle is parked for 7–8 minutes, the engine temperature will drop by a maximum of 10°C.
