At what temperature does the MG6 radiator fan turn on?

The radiator fan of the MG6 will start operating when the temperature exceeds 90 degrees. If the temperature exceeds the midline on the water temperature gauge, it indicates high water temperature. The following are the solutions for excessive radiator temperature in the MG6: 1. If the high temperature is caused by insufficient coolant, water needs to be added. However, to prevent engine damage, do not add water immediately. Usually, you should first open the car's hood, then open the engine cover for ventilation and heat dissipation, and add water only after the coolant temperature has dropped. 2. If the water pump failure causes high water temperature, it may be due to seized bearings or damaged impeller blades. The possibility of seized bearings is low, and replacing the damaged impeller blades should suffice. 3. If you find that the engine water temperature is too high and the electric fan is not rotating, it indicates that the fan's fuse or the temperature control switch has burned out. In this case, remember not to turn off the engine. First, open the hood and pour cold water on the car's radiator to quickly lower the water temperature. Additionally, be careful not to immediately open the radiator cap, as the hot water could cause burns.
I've been driving my MG6 for two years, and the radiator fan usually kicks in between 90 to 95 degrees Celsius, which is the normal operating temperature for the engine. During my last check-up, the repair shop mentioned that the fan is controlled by the water temperature sensor—it starts spinning to cool things down when the temperature rises. If you're on the highway or stuck in traffic and the water temperature soars without the fan activating, there might be an issue with the sensor or the fan itself, and it's best to get it checked as soon as possible. My usual practice is to keep an eye on the dashboard's water temperature warning light; if it turns red, I stop to let the engine cool down to avoid overheating and cylinder scoring. In the summer, when the air conditioning is on, the fan works more frequently. For maintenance, I change the coolant every six months and keep the radiator clean, which helps prolong its lifespan and prevents overheating issues.
As an enthusiast with over a decade of experience in vehicle control systems, I can share that the MG6's radiator fan is designed to activate within the 90-100°C range. The vehicle's computer monitors engine temperature, and once it exceeds the set threshold, sensor signals trigger the relay to engage the fan. If the fan fails to operate, check for blown fuses or loose wiring connections. It's advisable to keep an OBD scanner handy for diagnostics – abnormal coolant temperature readings often serve as warning signs. While noticeable fan noise during operation is normal, unusual sounds may indicate bearing wear requiring maintenance. Routine maintenance should prioritize checking coolant levels and purity, as degraded fluid lowers the boiling point, causing premature fan activation and increased workload.
