Magotan b6 water pump is broken, and the warm air is not hot. Because the heat source of the warm air comes from the engine coolant, and the coolant can only circulate in the warm air tank after the pump works to generate pressure, because the pump is damaged, the warm air disappears or is not warm.
The following are the symptoms of water pump damage:
1, the damage of the water pump will weaken the cooling circulation ability or even not circulate, and the coolant will boil;
2. Water leaks near the engine water pump. Coolant leakage will leave traces of coolant color on the vent hole of the water pump, leading to the phenomenon of high water temperature after insufficient coolant;
3. When the engine is working, the water pump makes abnormal sound. The abnormal sound of the water pump may be caused by foreign matter inside or bearing wear.
