What causes the high water temperature in the Sylphy?

[Wade]

The reason for the high water temperature in the Sylphy is a malfunctioning water pump. When the water pump fails, the water on the engine's heat conduction side cannot circulate in time, causing the water temperature to rise rapidly after the engine starts, leading to cooling system failure, water temperature alarm, and phenomena such as "boiling over." If detected early and appropriate measures are taken, more severe failures like cylinder scoring due to poor cooling can be avoided. The following are symptoms of a damaged water pump: 1. Reduced cooling circulation capacity: A damaged water pump can weaken or even stop the cooling circulation, leading to coolant boiling over; 2. Coolant leakage near the water pump area of the engine: Leaking coolant leaves traces of coolant color on the water pump's ventilation holes, resulting in symptoms like high water temperature due to insufficient coolant; 3. Abnormal noise from the water pump during engine operation: The noise may be caused by internal foreign objects or bearing wear.
