How many cans of refrigerant are needed when replacing the compressor on a Baojun 730?

When replacing the compressor on a Baojun 730, approximately 4 to 5 cans of refrigerant are required. High-pressure side liquid refrigerant charging: This method is suitable for charging after leak detection and vacuuming. Note that the compressor must not be turned on during this process, the engine should be off, and the refrigerant can must be inverted. Low-pressure side charging: This involves charging with gas, which is characterized by a slower filling speed and is typically used for refrigerant replenishment. Automotive refrigerant, commonly referred to as Freon, is the substance used in car air conditioning systems. It continuously circulates within the refrigeration system and achieves cooling through changes in its own state.
After replacing the compressor of the Baojun 730, it's necessary to refill the system with new refrigerant. Based on my personal experience from helping friends with similar issues at my own repair shop, the factory air conditioning system of the Baojun 730 typically requires about 550 grams of refrigerant. Since a standard refrigerant canister holds 300 grams, you'll need approximately one and a half to two canisters, depending on how thoroughly the system was evacuated during the replacement. If you have a professional shop handle the job, the technician will first vacuum the system to check for leaks, then precisely refill it to ensure optimal AC performance. When I did it myself, I used two full canisters to account for potential losses. I'd advise against DIY attempts to avoid leaks or uneven filling, which could impair cooling efficiency or even damage the new compressor. Regular AC maintenance, like checking the hoses during car washes, can reduce the need for such major repairs.
As an experienced car repair veteran, the amount of refrigerant needed for a Baojun 730 after replacing the compressor depends on the situation. Generally, two 300-gram cans of refrigerant are sufficient, as the total system capacity is about 500-600 grams. However, during the replacement process, residual old refrigerant or air may remain in the pipelines, so I recommend going to a repair shop to use specialized equipment for evacuation and measurement to ensure precise filling. Recalling the last maintenance, a fellow car owner used 1.7 cans after replacing the compressor, and the results were good. In terms of cost, each can costs a few dozen yuan, which isn't expensive, but labor and the compressor are the main expenses. The key is to avoid adding refrigerant blindly by yourself, as uneven pressure can cause component failure or leaks, affecting driving safety. Addressing small issues promptly can save you a lot of money in the long run.
The amount of refrigerant added when replacing the compressor should follow the vehicle's original specifications. The standard refrigerant charge for the Baojun 730 is approximately 500-550 grams. Since a common refrigerant canister contains 300 grams, 1.5 to 2 cans will be needed. After replacement, professional procedures including vacuuming and pressure testing are essential to prevent leaks or system inefficiency. From an environmental perspective, waste refrigerant must be properly recovered to avoid pollution. I recommend consulting a 4S dealership, as they use calibrated tools to ensure precise refrigerant charging, which saves money and guarantees quick cooling of the air conditioning system.
