The working principle of the water pump connecting the thermostat water pipe is based on the wax principle. When the coolant temperature is low, the paraffin remains solid, the thermostat valve is closed, and the coolant circulates small inside the engine, helping the engine heat up rapidly. As the temperature of the coolant rises, the paraffin gradually melts and expands, pushing the valve of the thermostat to open, and the coolant flows through the radiator for large circulation, effectively dissipating heat
The function of the automobile water pump connected to the thermostat water pipe is to automatically regulate the water into the radiator, adjust the cooling system's heat dissipation capacity, and ensure that the engine operates in the appropriate temperature range. If the thermostat main valve is opened too late, it will cause the engine to overheat; Open too early, the engine preheating time will be extended, the temperature is low
