What is the reason for the water not circulating in the Volkswagen Lavida?

[EverlyAnn]

The reason for the water pump not circulating in the Lavida is: air in the water channel. Methods for dealing with a damaged water pump: When the water pump shows faults such as water leakage or abnormal bearing noise, it needs to be replaced promptly. Failure to replace a damaged water pump can affect the cooling system and may cause the engine to overheat. Symptoms of a damaged water pump: A damaged water pump can weaken or even stop the cooling circulation, leading to coolant boiling. There may be coolant leakage near the water pump area of the engine. Leaking coolant will leave traces of coolant color on the water pump vent holes, resulting in symptoms like high water temperature due to insufficient coolant. The water pump may produce abnormal noises when the engine is running. These noises could be caused by internal debris or bearing wear.
