How much refrigerant should be added to the BYD F3?
3 Answers
BYD F3 refrigerant should be added 600g~700g. The following is a brief introduction about BYD Tang: 1. Exterior design: The luxury and premium models are not equipped with door sill plates with welcome lights but are equipped with headlight height adjustment. In addition, the speed edition has exclusive performance kits. In terms of dimensions, the Tang measures 4815/1855/1720mm in length, width, and height, with a wheelbase of 2720mm, a minimum ground clearance of 180mm, and a curb weight of 2220kg. 2. Interior features: The mid-to-high-end models are also equipped with seat heating, electric steering wheel adjustment, memory function, ambient lighting, and second-row multimedia control. In addition, the flagship and speed editions are also equipped with remote driving and automatic parking assistance.
The BYD F3 typically requires 500 to 600 grams of R134a refrigerant, with the exact amount depending on the model year and production batch. I've personally repaired several of these vehicles, and the standard is usually around 550 grams in most cases. However, never add refrigerant blindly—first use a pressure gauge to check if the system pressure is normal. Low pressure indicates a leak, which must be repaired before adding new refrigerant.
When driving this car, pay attention to the air conditioning outlet temperature. If cooling performance weakens, it may be due to insufficient or aged refrigerant. It's recommended to check it once a year before summer to avoid discomfort during hot weather. If you're unfamiliar with tools, it's best to take it to a professional repair shop. They use gauges for precise operations—overfilling can shorten compressor life, while underfilling leads to poor cooling.
After servicing, test the system for half an hour to ensure no leaks and that cooling efficiency meets standards.
My F3 has been running for eight years, and I remember the refrigerant charge was around 550 grams. I've refilled it myself twice—you need to buy branded R134a refrigerant and a charging kit. First, turn off the engine and let the cooling system settle, then refill via the low-pressure pipe port. Don’t exceed 600 grams, as overcharging can burn out the compressor coil. Daily habits matter: regularly clean the AC filter to prevent clogging and check the pipes for oil stains (indicating leaks) during seasonal changes. Cost-wise, a refrigerant refill plus labor runs a few hundred bucks, but you can save by booking discounted maintenance services online. The cooling effect is immediate after refilling, significantly improving driving comfort. I recommend learning some basics for emergencies.
