Where is BYD f3 heating box?

In the engine compartment. BYD F3 is an a+ class passenger car of BYD Auto, which officially rolled off the assembly line on April 16, 2005. BYD f3 warm air small water tank is in the engine compartment. If it is found that the antifreeze in the water tank is lower than the minimum scale value (the normal value of antifreeze should be between MAX and min), it should be added in time, and the amount to be added depends on how much it is missing, otherwise it will affect the antifreeze performance of the engine.
