What are the solutions for high temperature in Wuling Zhiguang?
2 Answers
The solutions for high water temperature in Wuling Zhiguang are as follows: 1. Cooling fan issue: If the cooling fan is not working, check if the fan is not rotating. Use a test light to check; if the test light is on, replace the cooling fan. If the test light is off, repair the wiring. 2. Radiator heat dissipation problem: Poor radiator heat dissipation may be due to excessive scale in the radiator, preventing proper water circulation, or the electric fan not rotating, leading to poor heat dissipation. The solution is to clean the radiator or replace it, and repair the fan. 3. Water pump issue: Poor water pump performance, slippage, or a detached impeller can all lead to poor water circulation and high water temperature. The solution is to replace the water pump. 4. Thermostat: If the thermostat fails to open correctly, it remains closed at low temperatures and should open at 90 degrees to start the large water circulation. If the thermostat does not open at 90 degrees, it will cause the water temperature to rise. The solution is to replace the thermostat. 5. Leaking cooling system: A leaking cooling system with insufficient water level can also cause the water temperature to rise. Check if the water level has decreased, and address any leaks promptly if found.
You asked the right question! Last year, my Wuling van also overheated while hauling goods, stuck on the highway in the middle of summer—it was nerve-wracking. I immediately pulled over and popped the hood to let it cool down. Never open the radiator cap directly, as the scalding coolant inside can spray out and cause burns. If the coolant reservoir level is low, top it up with purified water as a temporary fix. The key is to feel the temperature difference between the upper and lower radiator hoses—if the upper one is hot and the lower one is cool, it means the thermostat is stuck and needs replacing. Radiator fins clogged with bug debris can also reduce cooling efficiency, so I rinse them with a water gun every three months. For long trips, I always keep bottled water and antifreeze in the trunk, along with a spare belt. The mechanic told me Wuling’s electric fan is the most prone to issues—if you hear it humming, that’s good; if it’s silent, check the fuse or relay right away. During oil changes, I ask the mechanic to squeeze the hoses—if they’re too stiff, it indicates abnormal pressure in the cooling system.
