Why does the Wuling Hongguang always show high water temperature?

The reasons why the Wuling Hongguang always shows high water temperature are: 1. Thermostat failure; 2. Water pump failure; 3. Radiator blockage; 4. High engine idle speed; 5. Slow or faulty cooling fan. The Wuling Hongguang is a microvan with body dimensions of: length 4390mm, width 1660mm, height 1750mm, and a wheelbase of 2720mm. It is equipped with a 1.2L naturally aspirated engine and a 5-speed manual transmission, delivering a maximum power of 56 kW and a maximum torque of 110 Nm. Its drivetrain is front-engine, rear-wheel drive, with a front suspension using MacPherson strut independent suspension and a rear suspension using leaf spring non-independent suspension.

Having repaired cars for many years, I've encountered numerous cases of high engine temperature in Wuling Hongguang, mostly caused by cooling system issues. The most common problem is insufficient coolant, possibly due to radiator leaks or rapid evaporation, especially noticeable in summer. Pop the hood to check the water level; if it's below the MIN line, promptly add distilled water or specialized coolant. Another frequent issue is the cooling fan not spinning—it should automatically activate when the engine heats up. Listen for a whirring sound while driving; if it's silent, the switch or motor might be faulty. A stuck thermostat can also cause temperature spikes by blocking coolant circulation. This component regulates coolant flow, and if it fails, temperatures become uncontrollable. I recommend stopping the engine immediately to let it cool before troubleshooting—never force it to run, as this could blow the head gasket, leading to costly repairs. Lastly, check if the sensor is malfunctioning, though rare, it can give false readings. Start with simple fixes like refilling coolant and inspecting the fan; leave complex issues to professionals to avoid major risks.

I'm the owner of a Wuling Hongguang, using it daily for hauling and deliveries. Last month, I also encountered the issue of the temperature gauge always showing high. After some troubleshooting, I first checked it myself and found the coolant was almost empty. Adding it to the standard level helped a bit, but the temperature quickly rose again. Later, I consulted an experienced mechanic who suggested it might be a slight radiator leak or a stuck thermostat. A simple method: after driving, listen for the fan sound—if it's not running, check if the cooling vents are blocked. In my case, the fan plug was loose, and tightening it solved the problem. Regular maintenance, including topping up fluids and cleaning, is crucial to prevent small issues from becoming big ones. It's good to keep some distilled water in the car for emergencies. If the temperature isn't normal, pull over and take a break before continuing. For safety, don't delay—head to a trusted small repair shop to get it fixed promptly. The cost is low, and it saves you a lot of hassle.

With decades of driving experience, never ignore the water temperature alarm. There are many reasons for Wuling Hongguang's high temperature. I'm used to regularly checking coolant levels and fan operation, and changing the fluid every six months for extra safety. The thermostat is a critical component—if it ages and fails to open, water flow stagnates and temperatures rise. If the water temperature spikes suddenly while driving, pull over, turn off the engine to cool for half an hour, then check the water level and top up—simple and effective. Don't push through to save time, or you'll damage the engine and face thousands in repairs. Prevention beats accidents—maintain good habits.
