What are the reasons for the high water temperature of Wuling Hongguang?

The reasons for the high water temperature of Wuling Hongguang are as follows: 1. Leakage in the cooling system or insufficient coolant; 2. Inaccurate or malfunctioning water temperature gauge; 3. Excessive scale in the cooling system, resulting in poor heat dissipation; 4. The radiator guard mesh or radiator core ventilation ducts are blocked by debris, leading to poor heat dissipation; 5. The water pump or fan belt is too loose or broken. Additional information: 1. Coolant needs to be replaced regularly. If not replaced for a long time, the freezing point of the coolant will rise, and the boiling point will decrease, which will affect the normal operation of the engine. When replacing the coolant, be sure to go to a professional shop and have professionals use professional equipment to replace it. 2. The thermostat of some cars may be damaged after prolonged use, which can also cause the water temperature to be too high. The thermostat is used to control the large and small circulation. If the coolant is always in a small circulation state, the coolant will not dissipate heat through the radiator, and the temperature of the coolant will also be too high. 3. If the thermostat is damaged, it needs to be replaced with a new one. In daily use, it is essential to maintain your car on time and use genuine parts during maintenance. Regular maintenance is relatively important for the car, and timely maintenance can keep the car in good condition. Maintenance involves replacing the fluids and wear parts of the car. The fluids in the car include coolant, transmission oil, engine oil, brake fluid, and power steering fluid.
I've encountered the coolant temperature warning while delivering goods in my Wuling Hongguang recently and have studied this issue thoroughly. The most common causes are insufficient or degraded coolant - antifreeze loses its cooling capacity over time. Next, check if the radiator fan is functioning properly; sometimes motor failure or loose wiring can cause the fan to stop working. A malfunctioning water pump is another critical point - if the belt is loose or the pump blades are corroded, coolant circulation gets disrupted. A thermostat stuck in the closed position also prevents heat dissipation, especially in older vehicles that have been running for seven or eight years. If the radiator's exterior surface is clogged with mud or willow catkins, heat dissipation efficiency plummets, making the engine more prone to overheating during heavy-load uphill driving. I recommend stopping immediately to inspect when this occurs, otherwise engine seizure could become a serious problem.
I've been driving the Wuling Hongguang for mountainous area logistics for ten years, and high water temperature is mostly due to these situations. Coolant leakage in the cooling system is the most common, caused by aging hoses or cracks in the radiator leading to coolant loss. Fan issues are also frequent; the fan won't start if the relay is broken or the temperature control switch fails. Internal blockage of the radiator is quite dangerous, as long-term use of hard water can cause scale to clog the pipes. If the water pump is damaged, you can hear abnormal noises, and belt slippage can cause similar problems. Severe engine carbon buildup directly affects cooling efficiency, especially for vehicles frequently carrying heavy loads. In such cases, I first turn the heater to the maximum setting to assist with cooling, then slowly pull over to check the coolant level in the overflow tank.
