Why does the Wuling Hongguang fan keep running and the water temperature remain high?

The following are the related reasons for the fan running and high water temperature: 1. Cooling system failure: There are many reasons that can cause the engine water temperature to be too high or even "boil over," such as damage to electronic components in the cooling system (thermostat, cooling fan, poor radiator heat dissipation, insufficient coolant, etc.). 2. Parking without turning off the engine: Pull over to the side but do not turn off the engine immediately! Because the coolant temperature is already very high, the cooling capacity has reached its limit. If the engine is turned off immediately, the boiling coolant will stop circulating (for most engines, the water pump is driven by the crankshaft). 3. Electric water pump: Of course, engines with electric water pumps fare better, but if the excessively high temperature is not cooled, the engine will still struggle to endure. Letting the engine idle for a while allows the continuously circulating coolant to mitigate the impact of high temperatures on the engine. 4. Check the coolant: Check if there is a shortage of antifreeze, which can cause the engine water temperature to rise. Also, check the circulation of the coolant to see if it is not flowing smoothly. Additionally, inspect components such as the water temperature sensor, water pump, thermostat, and cooling fan, as any of these could lead to an increase in water temperature.
I've driven the Wuling Hongguang for several years and encountered the issue of the fan continuously running with high water temperature several times. It's usually caused by insufficient coolant. I recommend first opening the hood to check the coolant reservoir level. If it's below the minimum line, it might be due to leakage or evaporation. Try adding the same type of antifreeze after checking. It could also be a faulty thermostat, which is a small valve controlling the fan's on/off operation. If broken, it can cause the fan to run non-stop. High water temperature can damage the engine, leading to smoke or piston damage. Other possibilities include radiator blockage or water pump aging, so it's important to get it checked and repaired as soon as possible to avoid compromising driving safety. In my case, adding coolant solved the problem, but regular inspection and maintenance are most important.
