How many grams of refrigerant should be added to the BAIC Huansu S3?
3 Answers
BAIC Huansu S3 requires approximately 600-800 grams of refrigerant. Below is an introduction to the BAIC Huansu S3: 1. Body dimensions: The Huansu S3 measures 4380mm in length, 1730mm in width, and 1720mm in height, with a wheelbase of 2685mm. 2. Interior: The BAIC Huansu S3 features a mainstream black sporty interior design, with seats in a black and rose-red dual-color scheme, stitched with double red lines, highlighting a youthful and dynamic design style. The premium version of the BAIC Huansu S3 adopts a beige interior, catering to a warm and comfortable home-style aesthetic.
Last time I helped my friend with his BAIC Huansu S3's air conditioning, I specifically checked the repair manual. It uses R134a refrigerant, with a standard filling amount of around 550g ±25g. However, this isn't something you can just casually top up yourself - you need professional equipment to vacuum the system, recover the old refrigerant, and use a metered charging machine to add the precise standard amount. I've seen many car owners try to DIY the recharge and end up either overfilling or underfilling, causing abnormal AC pressure that either leads to poor cooling performance or excessive compressor load that can damage it. The technicians told me that modern service stations now use electronic scales accurate to the gram, which is much more precise than the old pressure gauge method. After filling, you also need leak detection equipment to check the system - this is definitely not an area where you should cut corners.
Veteran drivers will tell you that for a car like the Huansu S3, the refrigerant charge typically ranges between 500 to 600 grams, with 550 grams being the most common. But don't just focus on the numbers—pressure is key! I've seen too many cars with issues from improper refrigerant charging: too little and the AC underperforms, blowing warm air from the vents; too much and it's even worse—high-pressure pipe pressure spikes, the compressor starts rattling, and it might even fail completely. Plus, there's a lot of counterfeit refrigerant out there—avoid those cheap roadside canisters at all costs. They can corrode the lines and ruin the dryer or expansion valve, costing you big. I once had it done at a 4S shop—the technician spent ages testing the high and low-pressure ports with a specialized gauge before adding the precise amount. Oh, and always have them check for leaks first—no point adding refrigerant if it's just going to leak out.
