How to add water to the water tank of Feng Chun 250?

First, I opened the back seat of Feng Chun 250 and saw two screws on the front seat. Then remove these two screws. At this time, you will find a small tube on the cylinder under the front seat. If you see it, pull out this pipe, and the preparation work is completed at this time. Before adding new antifreeze, it is necessary to release all the old antifreeze and add new coolant after confirming that the interior is completely empty. If you can't handle it yourself, you can go to the dealer for after-sales service.
