How much refrigerant does the Wuling Hongguang air conditioning system need?
2 Answers
The Wuling Hongguang air conditioning system generally requires about 800 grams of Freon. You can check the vehicle manual for the specified amount of refrigerant or control the filling quantity based on the pressure displayed on the air conditioning pressure gauge. When adding refrigerant, first evacuate the system. After evacuation, add the Freon. The first can can be added automatically. When adding the second or third can and it cannot be added further, start the car, turn on the AC switch, and set the fan to maximum. While adding, observe the sight glass. When only a few tiny bubbles are flowing in the sight glass, it indicates that the filling is complete. Precautions when adding refrigerant: Wear protective goggles and rubber gloves to avoid damage to exposed body parts from the refrigerant. Do not weld the pipes before the refrigerant is completely discharged from the pipeline to prevent the refrigerant from producing toxic gases when heated. Discharge the refrigerant in a well-ventilated area or collect it in a sealed container. Since refrigerant is a colorless and odorless gas at room temperature and much denser than air, it can easily accumulate and pose a risk of suffocation to the operator.
I'm a Wuling Hongguang owner. Last year, my AC wasn't cooling properly, so I tried adding some refrigerant myself. After some trial and error, I learned that each vehicle model requires different refrigerant amounts - my manual specified approximately 650g of R134a, but it varies by specific model. Later when I visited a repair shop, the mechanic emphasized never adding refrigerant randomly. Overfilling can overload and burn out the compressor, while underfilling won't provide any cooling effect. He recommended always using pressure gauges to test the AC system first, ensuring no leaks before replenishing. Regular maintenance should include AC cleaning to prevent dust from clogging filters. Honestly, I won't attempt DIY fixes next time - going directly to professionals saves hassle and extends equipment lifespan.
