BYD f3 heater water tank is broken, can you protect your rights?

Hello, I suggest you change it. Removing the hot air tank requires removing the workbench. In case it breaks not long after welding, it's too much trouble and not worth it. I hope I can help you. Have a nice trip. If there is something wrong with the car, ask the car master. 4S shop professional technician, 10 minutes to solve.
