What to Do When the Wuling Rongguang's Heater Isn't Hot?
3 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.
As a Wuling owner, I once encountered an issue with the heater not blowing warm air during summer and initially thought the AC was broken. Start with the basics: pop the hood to check for coolant leaks or aging hoses—my Rongguang had low fluid levels due to a leaking water pump. Next, inspect the cabin’s airflow controls; if it’s set to heat mode but the airflow is weak, it might be a blower motor issue, requiring filter cleaning or new fan blades. In my case, after hours of troubleshooting, it turned out to be a faulty thermostat—replacing it with an OEM part at the repair shop took just 20 minutes. Don’t overlook the heater valve switch either; sometimes a glitchy button just needs a circuit reset. Always monitor the temperature gauge while driving—only turn on the heater once it reaches normal operating range, or the cold engine won’t produce heat. In winter, warm up the car for three minutes before driving to ensure proper circulation and avoid trouble. If all else fails, contact a service center—they’re quick and affordable.
