Why Does the Wuling Hongguang Have High Water Temperature?
4 Answers
Wuling Hongguang's high water temperature is caused by air in the cooling system, debris in the radiator, abnormal coolant in the water tank, or sand holes/perforations in the cylinder block's water jacket. Below are detailed explanations of these causes: Air in the cooling system: This can create airlocks, disrupting coolant circulation and leading to excessive engine temperature. Debris in the radiator: If the vehicle is driven on dirt roads or muddy paths for extended periods, debris may accumulate on the radiator, eventually reducing cooling efficiency and causing high water temperature. Abnormal coolant in the water tank: If the temperature is too high or the temperature indicator light keeps flashing, stop to check whether the coolant level is normal and inspect for leaks around the water tank or hoses. If no abnormalities are found, top up the coolant and continue driving. Sand holes or perforations in the cylinder block's water jacket: If, after addressing the above issues, the temperature remains high after driving a certain distance and coolant continues to decrease upon inspection, this may indicate leaks due to sand holes or perforations in the cylinder block's water jacket, requiring immediate repair.
That day, the temperature gauge on my Wuling Hongguang suddenly spiked, so I immediately pulled over and checked, only to find the coolant reservoir was empty. There are three common reasons for high engine temperature in this car: first, a coolant system leak or insufficient fluid, like a hole in the radiator or hose, causing rapid evaporation on long drives; second, a faulty or non-working fan, especially in summer traffic jams when cooling is poor, possibly due to battery power or a loose belt; third, a stuck thermostat or water pump failure, preventing coolant circulation. Additionally, a radiator clogged with dust or an overheating engine itself can also cause trouble. I recommend shutting off the engine immediately if the warning light comes on and turning on the heater to dissipate heat—don’t wait until the engine gets damaged. Afterwards, visit a repair shop to diagnose the issue. Regularly change the coolant and clean the radiator fins every six months as preventive maintenance.
High coolant temperature in Wuling Hongguang is often caused by cooling system malfunctions. Worn-out water pump (leaking or corroded impeller) disrupts fluid circulation; faulty fan switch sensor or burnt motor prevents fan operation; thermostat stuck in closed position blocks coolant flow; radiator clogged with debris or leaves reduces cooling efficiency. Check for leaks at joints or tank seams using flashlight traces. For emergency DIY, add distilled water (never mix types). Prioritize thermostat and fan assembly replacement during repairs, and keep OBD tools handy for diagnostics. Wuling engines have weaker cooling - simply reduce speed during hill climbs.
When the water temperature warning light comes on, first slow down and pull over, then turn off the engine and set the heater to maximum. Check the coolant reservoir level; if it's low, you can temporarily add purified water. Listen for the sound of the fan to see if it's running. Don't attempt repairs without the proper tools. Common causes include coolant leaks, fan failure, a faulty thermostat, or blocked heat dissipation. Prevention: Always monitor the temperature gauge when refueling, and avoid steep climbs in hot weather.
