The high water temperature of the engine (on the premise of no shortage of water) is mainly due to the phenomenon that the cooling fan is turned on late in cars using electronic fans, and it is also due to poor heat dissipation, such as the low rotation speed of the cooling fan, which needs to be exhausted in time.
Extended data:
The cooling system of automobile engine is a forced circulating water cooling system, that is, the pressure of coolant is increased by a water pump, so that coolant is forced to circulate in the engine. The cooling system is mainly composed of water pump, radiator, cooling fan, compensation water tank, thermostat, water jacket and accessories in engine block and cylinder head.
In the cooling system, there are actually two cooling cycles: one is the main cycle of cooling the engine, and the other is the heating cycle in the car. Both cycles are centered on the engine and use the same coolant.
