1. Coolant leakage: Red water may be coolant, also known as coolant and antifreeze. After replacing the hot air tank, the cooling system may leak, causing the coolant to leak under the chassis. The leakage may be caused by improper installation of the heating box or other cooling system components.
2. Liquid leakage in the steering system: The liquid in the steering system is generally red, so the leaked liquid may come from the pump, pipeline or joint.
