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

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.
I once experienced a situation with my Volkswagen Lavida where the coolant wasn't circulating, causing the water temperature to skyrocket and nearly leaving me stranded. After inspection, it turned out to be a problem with the water pump—either the impeller inside was worn or the shaft seal was leaking, preventing the water from being pumped. Another common cause is a stuck thermostat that fails to open, which should allow coolant to flow into the engine when it's hot but instead blocks the path due to being jammed. Low or leaking coolant can also disrupt circulation, especially during long drives in hot weather when the fluid level drops to its minimum. Also, remember that pipe blockages can occur, such as when the radiator is clogged with debris. My advice is to check the coolant level immediately and top it up if low. If that doesn’t help, head to a repair shop—a professional mechanic can test the water pump and thermostat. Continuing to drive with these issues can severely damage the engine. Don’t skip regular maintenance; inspect the cooling system at least once a year.
After years of driving the Volkswagen Lavida, common issues with water circulation often stem from water pump failure—when the impeller is damaged, water flow can't be pushed, causing it to stop. A faulty thermostat is another culprit; if it gets stuck in the closed position, it blocks the passage. Coolant leaks in the system can lead to low fluid levels, preventing proper circulation, or air pockets in the pipes can block the flow. A broken belt might also cause the water pump to stop. From experience, it's recommended to first check the coolant reservoir level and top it off to see if the situation improves. If not, inspect the pump and thermostat. During repairs, avoid DIY disassembly to prevent damage—seek a professional shop for tool-based diagnostics. Regular maintenance, with check-ups every six months, can save you from costly major repairs.
