What to Do When the Wuling Rongguang's Heater Isn't Hot?
2 Answers
When the Wuling Rongguang's heater isn't hot, the first step is to determine the cause. The method is simple: check the temperature of the two inlet pipes of the heater's small radiator. If both pipes are hot, the issue is likely with the airflow control mechanism. Conversely, if both pipes are cold or one is hot and the other is cold, the problem lies in the cooling system. The Wuling Rongguang is a model under SAIC-GM-Wuling, with body dimensions of 4490mm in length, 1615mm in width, and 1900mm in height. In terms of power, the Wuling Rongguang is equipped with a small-displacement (1.2-liter) high-power B-series engine, with a maximum power output of 60.5KW and a maximum torque of 108NM.
I usually enjoy fixing my own car. If the Wuling Rongguang's heater isn't blowing hot air, you can start by checking a few things yourself. First, inspect the coolant level in the radiator—if it's low, top it up with the same type of antifreeze (remember, don't use water, as it can freeze in winter and damage the engine). Then, feel the temperature of the heater core's inlet and outlet hoses. If one is hot and the other cold, it might be clogged, and you'll need to clean out any scale buildup inside. When I encountered this issue, I found the thermostat stuck in position, so I bought a new one and replaced it. Also, test the fan speed—turn it to high and see if hot air comes out. DIY repairs can save you hundreds, but don’t rush to disassemble parts; just make sure you have the right tools. Heater system problems often stem from poor maintenance, so I recommend a thorough check before winter each year to avoid shivering on the road, which can affect driving safety. A quick tip: set the AC to recirculation mode to prevent cold outside air from mixing in. If you can't figure it out, it's best to call a professional—they can fix it quickly.
