What is the standard amount of refrigerant in grams for the Baojun 730?
2 Answers
Baojun 730 requires approximately 4 to 5 bottles of refrigerant. Below is relevant information: 1. Function of refrigerant: The refrigerant works by utilizing its physical changes to absorb heat from the car's interior. Under high pressure, the refrigerant forms a liquid and releases heat. 2. Effects of overfilling refrigerant: It increases the pressure in the air conditioning system, triggering high-pressure alarms in the car's AC, frequently interrupting the compressor's operation; reduces cooling efficiency; damages AC components; and may cause the car's AC pipes to burst. 3. Methods for refrigerant discharge are as follows: Prepare a car refrigerant recovery and charging machine along with a refrigerant tank. Connect the machine's pipelines to the car's AC high and low-pressure pipes, set the required amount of refrigerant to be recovered, and start the recovery process.
I remember the last time I added refrigerant to my Baojun 730 myself, I specifically checked the manual and consulted with the 4S店 technician. This car uses HFC-134a refrigerant, with a standard amount of about 550 grams, with a tolerance of no more than 25 grams. Adding too little won't cool the air properly, while adding too much can actually worsen the cooling and damage the compressor. Once, to save time, I had a roadside shop do it, and they just filled it up completely, causing the high-pressure pipe to freeze up—driving in summer felt like a sauna. Later, I went to a professional shop where they used equipment to vacuum and refill it with the correct amount, which fixed the problem. I genuinely advise everyone to check the pressure gauge readings and not just rely on the refrigerant can's scale. Now, when I turn on the AC in hot weather, I make a habit of feeling the low-pressure pipe's temperature—if it cools quickly, it means the amount is just right.
